The idealism of a hemodynamic software

The complexity of hemodynamic models has prevented clinicians from getting the insights out of the models when relating the clinical issues with the hemodynamic model. Visualization is the most persuasive way to illustrate a hemodynamic equation, and simulation is needed to visualize how the equation changes upon the manipulation of the coefficient of equations. Thus, the success of the hemodynamic software depends on how easy it is to work with visualizing the hemodynamic model and how effective it is for clinicians to draw insights from the models.

Additionally, it would be better if the following conditions are fulfilled: -1) an engineer takes care of the CPU time and memory management when combining and implementing numerous hemodynamic models published so far; -2) the simulation software provides an alternative interface other than GUI, which could enable experts to work more flexibly with the hemodynamic model; -3) components such as device interface, medical statistics, and artificial intelligence are coherently integrated in order to facilitate hemodynamic research.

Infrastructural aspects of each component

Each component will be the basis upon which other components can be built. This circulative data flow in the architecture diagram will eventually contribute to the development of other components synergistically. In other words, when considering the final overall goal of this software project as facilitating the data flow according to the software architecture, one part of the development will benefit the other part of the research.

The hemodynamic workbench software will be implemented to provide the following infrastructural functionalities: (1) To receive signals from the hemodynamic instrument; (2) To extract necessary information by wavelet analyses; (3) To understand the data according to the hemodynamic model and simulation; (4) To provide medical statistics; (5) To perform an action by reinforcement of the learning process.

Why the thoracic cavity for hemodynamic software and robotic surgery?

The thoracic cavity is intriguing in regards to its demanding physiological and computational potential. It is physiologically intriguing how the lungs and the heart are directly governed by the laws of physics: the hemodynamics during blood circulation and respiration with relation to auscultation, electrocardiography, ECMO and anesthetic machines. Computationally, a kernel-level device driver and Bayesian-based machine learning algorithm can be employed for (1) monitoring of the states of the thoracic organs, (2) computer-assisted hemodynamic modeling and simulation, and (3) machine learning for information processing. In addition, the thoracic cavity is ideal for a specialty that sits on the cusp between surgery and engineering to perform intellectually and technically challenging surgical robotic R&D projects on the organs encased by bones, which are best accessed and manipulated by a thin robotic hand instrument with ergonomic advantages. This will widen the indication of robotic cardiovascular surgery with new surgical procedures that integrate various additional hemodynamic devices and computational support.

"Surgeons must progress beyond the traditional techniques of cutting and sewing that have been their province since surgeons were barbers to a future in which approaches involving minimal access to the abdominal cavity are only the beginning." - Pappas et al. (2004) N Engl J Med.


(1) Device Interface index

Device driver interface component will enable the software to access raw data directly from a device. Biomedical companies seem to welcome the idea of enabling third parties to write software for their devices, which is exemplified by 3M providing an SDK (Software Development Kit) to allow people to write software for its Bluetooth stethoscope. However, my ultimate goal will be to make one step further by implementing the kernel-level device driver that would connect devices more fundamentally (as compared to existing SDK) and, therefore, to establish an integrative and flexible hemodynamic workbench.
    Some EKG classification articles (Lee, 2013) (Lihuang, 2010) relied exclusively on the MIT-BIH arrhythmia database or the standard test material to evaluate their arrhythmia detection algorithms. However, to the best of our knowledge, the difficulty of acquiring additional new raw EKG dataset due to the absence of open-source device interface for EKG instrument may be at least partially attributed to those researchers's having to work exclusively on MIT-BIH arrhythmia database. Therefore, if this software can receive the EKG raw stream over a WiFi or USB connection from instruments, future engineers can acquire additional test materials by collecting further raw EKG data alongside with corresponding EKG diagnoses, directly.
    Nonetheless, companies would be cautious about opening their device protocols for my implementing the kernel-level device interface, since doing so might change the company's marketing strategies and policies. Therefore, continuous improvement of Project nGene.org® in the long-term to gain agreement concerning its clinical pragmatism and to embrace clinicians' needs by providing an easy-to-write environment for their own scripts will have to be prioritized over this kernel component.


(2) Waveform Analyses index

"(2) Waveform Analyses" component pre-processes the raw wavelet data directly from the devices via the "(1) Device interface" component. In order to handle the raw wavelet dataset, such as EKG, lung and heart sounds, etc., two core algorithms have been chosen to be common denominating features: Independent Component Analysis (ICA) separates the mixed wavelets, whereas Support Vector Machine (SVM) classifies things after being trained.
    Its benefit can be illustrated by how this feature may change the existing flow. These machine-learning components can be used tentatively, until a more precise implementation of the classification for wavelets is implemented later in the point of time. For example, machine-learning algorithms for classifying EKG would be no match for a manually-written conditional statements implemented according to the Sokolow-Lyon Criteria for left ventricular hypertrophy (LVH) (Sokolow, 1949), as it would be nonsensical for training SVM to distinguish whether the summation of the S wave in V1 and the R wave in V5 or V6 is greater than, specifically, 35mm or not for LVH. However, until the manually-implemented code is developed according to certain criteria, it may be better to employ machine-learning features to accommodate wavelets in order to accelerate research and development in the meanwhile.
    For an example of embedding this software into the educational CPR kit mentioned above, the AED (Automated External Defibrillation) algorithm requires distinguishing normal EKG from various arrhythmia cases. However, since the MIT-BIH "arrhythmia" database does not have normal EKG dataset, the "(1) Device Interface" component can be used to collect a normal EKG raw dataset. Once normal EKG data with diagnoses are accumulated, then the SVM algorithm can be trained to classify whether it should be defibrillated, synchronized cardioversion, non-shockable, and normal, until the development of a more accurate manually-programmed classifying algorithm.


(3) Hemodynamics index

Project nGene.org® intends to facilitate research on the hemodynamic model, not only to better understand the physiology, and but also to gain further insights into improving the model. There are numerous equations published already and in the future and it may be too late if we just wait for the echocardiography manufacturing engineer to implement the module for the equation we need. Unless it is open-sourced, it cannot possibly follow the speed of insights during research. Yale Neuron is open-sourced with GUI for simulating neuron network; however, in my opinion, no matter how flexibly a software architect may implement its GUI, it cannot be on a par with the flexibility and creativity of new equations and insights of clinicians in the future.
    Therefore, Project nGene.org® tries to circumvent this problem by integrating R script so that clinicians can add their equations to test those features during echocardiographic measurements on the flies. At the same time, I believe that the success of earning popularity depends on how easy and generic it is for clinicians to add and modify the source code. Since clinicians do not have time to spend on learning, it is very important to make it very intuitive to make them willing to invest their time. I think that clinicians will invest their time only if they can get it intuitively.


(4) Medical Statistics & (5) Machine Learning index

"(4) Medical Statistics" is something that I do, not as a destination, but as a necessary step. To put it straightforwardly, the ultimate goal is "(5) Machine Learning". "(5) Machine Learning" component is pushed back on the priority list in the Masterplan Chart, because the software is designed to provide the following different types of dataset for the machine-learning algorithms: (i) Directly from hardware via the kernel program part, "(1) Device Interface"; (ii) Indirectly processing the wavelets raw data from instruments, "(2) Waveform Analyses"; (iii) Parsing and processing articles, especially meta-analysis and survival curve data, "(4) Medical Statistics", via a semantic web.
    The semantic web is a very suitable piece for medicine due to several reasons: (1) It is very flexible to integrate other semantic webs together, such that it can be used as a knowledge database with numerical information. (2) This numerical information with a network form can be fed into Bayesian-based machine learning. (3) Meta-Analysis is one of the forms of very specialized information that are available in the domain of medicine, and getting the hazard ratio from the survival curve for meta-analysis was, in my opinion, the most difficult methodology and the most challenging technical barrier when building a semantic web database.




Software Architecture (The 2024 Edition)

As both a medical doctor and a software engineer, with experience in echocardiography and serving as an IRB chair, I bring a unique, chimeric perspective to the development of Project nGene.org®. This dual expertise is crucial in navigating the challenges outlined in three seminal works: The Mythical Man-Month, The Innovator's Prescription, and Crossing the Chasm.

The Mythical Man-Month: In the interdisciplinary world of software and medicine, I have learned that communication is key to bridging the gap between different fields—what I call the "Apple and Orange" problem. This lesson was driven home by my experiences and reinforced by Fred Brooks' The Mythical Man-Month. Brooks warns that simply adding more manpower to a project often increases complexity rather than reducing it. As a chimera, trained in both fields, I strive to minimize this intercommunication complexity, ensuring that the app remains manageable and effective without the need to constantly increase resources.

The Innovator's Prescription: The Project nGene.org app is not designed to guarantee perfect accuracy in recognizing visual or auditory data through its camera or microphone. Instead, drawing from The Innovator's Prescription, the app's primary objective is to disrupt traditional clinical workflows by simplifying and democratizing complex medical processes. My goal is to enhance the clinical experience, making it more efficient and cost-effective, while keeping the app accessible to a broader audience. Additionally, by making parts of the codebase open-source, we are fostering a collaborative environment that invites continuous innovation and improvement.

Crossing the Chasm: Finally, in alignment with Geoffrey Moore's Crossing the Chasm, this app is strategically focused on identifying and capturing its niche market within the healthcare industry. By targeting a specific segment that values innovation, efficiency, and cost-effectiveness, the app aims to establish a strong foothold and gradually expand its user base. I am committed to ensuring that the app not only provides core technology but also offers a comprehensive ecosystem of support and services. This approach ensures seamless integration into existing clinical workflows, addressing the pragmatic needs of a broader user group and facilitating the app's transition from early adopters to the early majority.

The software project is meticulously crafted, with each component acting as a foundational pillar for subsequent innovations, establishing a circular data flow within its architectural framework. This methodology is anticipated to synergistically propel the evolution of the platform's elements. The project's paramount objective is to refine data circulation to mirror its architectural blueprint, ensuring that progress in one domain reciprocally amplifies research endeavors across the board. The hemodynamic workbench software is poised to offer essential functionalities: (1) capturing signals from hemodynamic instruments, (2) distilling vital information via wavelet analyses, (3) decoding data through hemodynamic models and simulations, (4) compiling medical statistics, and (5) executing actions based on a reinforcement learning algorithm.

Implementing the software marks the recrystallization of his professional journey, serving as a compass to navigate his career. This endeavor will not only guide him towards new horizons but also enrich his understanding for further development, ultimately fulfilling his life's purpose and enhancing his sense of satisfaction.


Why the thoracic cavity for hemodynamic software and robotic surgery?

The thoracic cavity, encasing critical organs such as the heart and lungs, presents a unique intersection of physiology and technology, demonstrating the profound influence of physical laws on biological functions. From a computational perspective, the integration of kernel-level device drivers with machine learning algorithms offers transformative potential in thoracic medicine. These technologies enable continuous monitoring of thoracic organ states through advanced waveform analyses, including ECG and ventilation monitoring waveforms (pressure, flow, volume), and auscultated mixed heart and lung sounds. Such detailed data acquisition is crucial for effective decision-making and patient management in real-time scenarios. The computational modeling capabilities, particularly in hemodynamic simulations, are further enhanced by incorporating echocardiography data. This integration is especially pivotal in addressing complex conditions like pulmonary hypertension, where accurate hemodynamic models can significantly improve the outcomes of interventions such as congenital heart defect surgeries in neonates. By simulating various physiological conditions, surgeons and clinicians can predict the effects of surgical interventions, thereby planning surgeries with higher precision and better prognostic outcomes. Moreover, the field of robotic surgery in the thoracic cavity is advancing rapidly, driven by machine learning algorithms that learn from thousands of surgeries performed by human doctors. This data not only informs the development of autonomous surgical robots but also supports the creation of new surgical techniques that integrate hemodynamic devices and computational support. The advent of slender robotic hand instruments designed specifically for the ergonomic constraints of thoracic surgery further underscores the technical sophistication in this field.

"Surgeons must progress beyond the traditional techniques of cutting and sewing that have been their province since surgeons were barbers to a future in which approaches involving minimal access to the abdominal cavity are only the beginning." - Pappas et al. (2004) N Engl J Med.


(1) Interface index

(2) Waveform Analysis index

(3) Hemodynamics index

The integration of computational modeling and simulation has revolutionized the field of hemodynamics, transforming the way cardiovascular conditions are studied and treated. The dynamic and interactive nature of hemodynamic simulations, as discussed in "Computational Thinking" by Peter J. Denning and Matti Tedre, goes beyond the capabilities of traditional graph drawing, which often falls short when dealing with the complex, variable nature of biological systems. Unlike static graphs that display a fixed dataset, simulations provide a real-time, interactive platform that allows researchers to modify parameters and observe how these changes affect the cardiovascular system. This interactivity is crucial for a detailed understanding of how blood flow and pressure react to various physiological changes, making simulations an indispensable tool in predicting the effects of alterations within the cardiovascular system and aiding in the development of effective treatments for heart diseases.

Advanced modeling and simulation techniques are particularly impactful in addressing the challenges of congenital heart defects (CHD) and pulmonary arterial hypertension (PAH). For instance, the development of logistic-based equations for estimating Pulmonary Artery Pressure (PAP), as noted in Project nGene.org®, underscores the practical application of theoretical models in a clinical setting. These simulations enable the visualization and analysis of cardiovascular responses to treatments in a risk-free environment, which is especially crucial in designing interventions for vulnerable populations such as neonates with CHD. The traditional approach to surgical interventions, fraught with significant risks, highlights the need for non-invasive methods facilitated by simulations. By simulating specific cardiovascular conditions associated with CHD and PAH, Project nGene.org® not only provides insights into the intricate factors influencing patient outcomes but also enhances the potential for successful treatments while minimizing risks.

The ongoing initiative to harness hemodynamic modeling and simulation in the development of neonatal CHD surgery simulations exemplifies the shift towards simulation-based planning and execution of surgical interventions. This approach not only refines the understanding and management of PAH within the context of CHD but also pioneers new methodologies for surgical planning. By creating highly accurate, virtual models where surgical strategies can be tested and refined, simulations ensure the highest level of safety and efficacy in neonatal CHD treatments.


(4) Medical Statistics & (5) Machine Learning index

Integrating "(4) Medical Statistics" into my work is not merely a destination but a vital step towards a broader objective: mastering "(5) Machine Learning". This component is strategically deferred in the Masterplan Chart, as the software is intricately designed to curate diverse datasets for machine learning algorithms through various means: (i) directly from hardware via the kernel in the "(1) Device Interface"; (ii) by processing raw wavelet data from instruments in "(2) Waveform Analyses"; and (iii) by parsing and analyzing medical literature, particularly meta-analyses and survival curve data, through "(4) Medical Statistics", utilizing a semantic web (or Web 3.0) approach. Initially, the semantic web seemed perfectly aligned with medical applications for several reasons: (1) Its inherent flexibility facilitates the integration of multiple semantic webs, creating a comprehensive knowledge database enriched with numerical data. (2) This numerically dense network is ideal for Bayesian-based machine learning applications. (3) Specifically, meta-analysis represents a form of highly specialized information within the medical domain, where deriving hazard ratios from survival curves posed a significant technical challenge and a methodological bottleneck in developing a semantic web database.

However, the rapid evolution of machine learning algorithms necessitated a shift in methodological approach. Acknowledging the advancements in deep neural networks and linear algebra techniques, especially Singular Value Decomposition (SVD), these methods now appear more apt for these objectives. This change in methodology is driven by the emerging efficiencies and capabilities of these algorithms in machine learning, signifying a pivotal adaptation to the evolving landscape of data analysis. This recalibration of approach, moving from a Bayesian-based semantic web to emphasizing deep learning and SVD, reflects a commitment to leveraging the most effective and advanced methodologies available in the field of machine learning. It underlines readiness to adapt and evolve in response to the dynamic nature of technological advancement and the continuous quest for more refined and powerful analytical tools.

The reconsideration of Bayesian algorithms also draws from a historical challenge in the field of artificial intelligence. Despite the Bayesian approach's flexibility and appeal, its application is marred by complexity in calculations beyond simple, restrictive assumptions. This complexity often necessitates approximation methods or sampling, which, while practical, diverge from dealing with the real posterior distribution directly. Further complicating the landscape was the neural network's initial inability to solve the exclusive OR (XOR) problem, a straightforward task achievable with basic digital logic gates but unattainable by a single-layer perceptron. Although it was known that multi-layer perceptrons could theoretically execute such tasks, the lack of effective training methods led to significant disillusionment and a temporary retreat from neural network research. This historical bottleneck highlights the limitations of early machine learning approaches and underlines the strategic pivot towards more advanced and capable methodologies, such as deep learning, that have since overcome these early challenges. (On February 5th, 2024, this segment of the software architecture underwent a revision to include sophisticated deep learning and SVD techniques.)


Robotic Surgery

RCT Meta-analysis: Robotic vs. Laparoscopic Surgery (Frank, 2018)

RCT Meta Analysis

Importance This review provides a comprehensive comparison of treatment outcomes between robot- assisted laparoscopic surgery (RLS) and conventional laparoscopic surgery (CLS) based on randomly-controlled trials (RCTs).
Objectives We employed RCTs to provide a systematic review that will enable the relevant community to weigh the effectiveness and efficacy of surgical robotics in controversial fields on surgical procedures both overall and on each individual surgical procedure.
Evidence review A search was conducted for RCTs in PubMed, EMBASE, and Cochrane databases from 1981 to 2016. Among a total of 1,517 articles, 27 clinical reports with a mean sample size of 65 patients per report (32.7 patients who underwent RLS and 32.5 who underwent CLS), met the inclusion criteria.
Findings RLS shows significant advantages in total operative time, net operative time, total complica- tion rate, and operative cost (p < 0.05 in all cases), whereas the estimated blood loss was less in RLS (p < 0.05). As subgroup analyses, conversion rate on colectomy and length of hospital stay on hysterectomy statistically favors RLS (p < 0.05).
Conclusions Despite higher operative cost, RLS does not result in statistically better treatment outcomes, with the exception of lower estimated blood loss. Operative time and total complication rate are significantly more favorable with CLS.

Robotic surgery cost, under the hood

Regarding the cost-effectiveness of robot-assisted laparoscopic surgery (RLS), it is generally perceived as more expensive. This perception raises questions about the viability of further employing RLS, especially amid concerns over its advantages in complications, conversion rates, and the extended operative time. However, from a patient's perspective, although numerous articles have closely compared the total operative costs between RLS and conventional laparoscopic surgery (CLS), finding a common objective ground is complicated—not to mention considering the exchange rate at the time of surgery (Morino, 2006). Moreover, the information may not be practically relevant to patients, as the total operation cost does not directly correlate with the actual payment by patients due to varying insurance policies across different companies, hospitals, and countries. Aboumarzouk et al. highlighted in their meta-analysis that the so-called 'total cost' fails to account for the 'social cost analysis', which considers the benefits of quicker recovery and shorter convalescence (Aboumarzouk, 2012).

Similarly, from the hospitals' perspective, the profitability of RLS should take into account not only the quantitative aspects such as the cost of equipment, operation time, training surgeons for both CLS and RLS considering their respective learning curves, and the impact of RLS's longer operative time on hospital revenue, hospital stay, blood loss, and insurance policies, but also qualitative factors. These include the surgeon's safety from infections like HIV, repeated radioactive exposure from bedside X-rays, and the comfort of surgeons during surgery by allowing them to sit. Lin et al. also noted that insufficient data and significant heterogeneity due to differences in skill, the extent of lymph node dissection, and the duration of the learning curve preclude a comprehensive meta-analysis of cost-effectiveness (Lin, 2011). Moreover, the unique capability of RLS for remote surgery in scenarios like war and rural areas should not be overlooked. Furthermore, it is empirically understood that the cost of new technology tends to decrease over decades. From the perspective of the public or investors in surgical robotics, it is advisable to consider these underlying factors when evaluating the cost-effectiveness of robotic surgery.

My general subjective opinion on surgical robotics

It may be surprising that the criticisms leveled at laparoscopic pioneers between the 1950s and 1990s bear a striking resemblance to those currently directed at surgical robotics. Most of the criticisms of conventional laparoscopic surgery (CLS), including 'higher complication rates than laparotomies ... attributable mainly to inexperience, and [e]ach procedure normally done via laparotomy [being] re-invented [with] trial and error,' (Page, 2008) are similarly applicable to robot-assisted laparoscopic surgery (RLS). Despite the harsh criticisms in the late 20th century, CLS has now become widely acknowledged as an indispensable surgical method (Pappas, 2004). Thus, mirroring the history of CLS, there remains the potential for RLS to achieve better clinical outcomes in the future, as knowledge and experience continue to accumulate through trial and error across society. This is especially relevant considering that the industry has now entered the era of Industry 4.0, or robotics.


ECMO (ExtraCorporeal Membrane Oxygenation)

ECMO meta-analysis on hazard ratios: Cardiopulmonary Diseases (Frank, 2020)

Extracorporeal membrane oxygenation meta-analysis of time-to-event data in cardiopulmonary disease in adults

In recognition of the benefits of extracorporeal membrane oxygenation (ECMO)[1], clinical outcomes have been the subject of multiple meta-analyses. Previous meta-analyses of ECMO treatment reported forest plots based on relative risks. Unlike a hazard ratio (HR), a relative risk does not consider the time to event and censoring and runs the risk of not using all the available information[2]. In other words, with respect to the patient mortality, the relative risk between ECMO and no-ECMO patient groups cannot avoid overlooking the critical factor of how ECMO has influenced the timing of each event or patient death over the course of disease progression.
   Previous meta-analyses have focused on a single indication presumably because, given the wide range of potential applications for ECMO, studying a particular patient population separately is a crucial step in terms of reducing confounding factors. The present study endeavors to investigate ECMO indications of cardiopulmonary disease as a whole and to list the findings of ECMO mortality in individual indications as subgroup analyses. This was done to ensure that a positive result of a particular indication is not automatically applied to a different patient population that may not have the same benefit, and thereby to prevent a potentially unnecessary intervention. Based on the ECMO indications[3, 4], the present study applies time-to-event data to evaluations of both the overall and individual cardiopulmonary indications of ECMO in adult patients in relation to relevant meta-analyses.
   To the best of our knowledge, the present meta-analysis is the first attempt to use time-to-event HR data to illustrate a forest plot of all-cause mortality from the use of ECMO in adult patients, in terms of both overall cardiopulmonary indications and individual indications as a subgroup analysis. As shown by the results of the overall analysis, across various indications of ECMO in cardiopulmonary diseases in adults, outcomes favored neither the ECMO group nor the no-ECMO group. However, as to the subgroup analyses, the reduction in mortality in the ECMO group was found in respiratory failure, whereas increased mortality in the ECMO group was noted in post-LTx, bridge to HTx, and post-HTx.
   These results should be understood not only in the context of weighing the benefits and adverse effects of ECMO, but also in consideration of patient selection issues. We could not help but notice the propensity to allocate the ECMO treatment to the poor patient conditions. In other words, the no-ECMO groups were selected and specified as groups of patients who required no invasive support[23, 24, 49]. Presumably, this was so because, in a daily practice, ECMO are used in desperate cases such as a cardiogenic shock where, without ECMO implantation, the mortality is critically high. This discriminate propensity of ECMO allocation appears to reflect the wide recognition of the benefits of ECMO treatments[1]but, at the same time, indicates a patient selection bias issue of a meta-analysis on the retrospective studies. Therefore, in addition to the intrinsic benefits and adverse effects of ECMO treatment, biased allocation of ECMO based on patient conditions as a whole appeared to contribute to the aforementioned results.
   In this regard, the significant reduction in mortality of the ECMO group in the patients with respiratory failure compared with the no-ECMO group is worthy of mention. That is, against the patient selection biases that presumably favor the superior outcome in the no-ECMO group, the significantly improved patient outcomes in respiratory failure in the concurring ECMO group is evident. Our result favoring the ECMO group in respiratory failure is consistent with previous meta-analyses for H1N1 pneumonia[65]and ARDS[66]. It can be tentatively proposed thatthe inclusion of the two RCTs, which is less apt to be influenced by the patient selection bias, may contribute to the significant reduction in mortalityof the forest plot due to the increased statistical power of the pooled studies. In addition,Annichet al.stated that themajority of patients with respiratory failure including ARDS has been well supported with veno-venous (V-V) ECMO[1]. In this regard, the increased likelihood of normal cardiac function in respiratory failure conditions could enable the more frequent use of V-V ECMO (or all the use of V-V ECMO[22]), which could avoid the complications of veno-arterial (V-A) ECMO, such as systemic embolization, arterial trauma, and increased left ventricular afterload[67, 68]. However, in consideration ofnumerous possible confounding factors of heterogeneities that may have influenced the mortality results, this hypothesisneeds to be enlightened by more meticulous reasoning that unleashes which factorscontributed to this deviation of respiratory failure subgroup analysis from the overall global analysis.
   Although we are aware of the fact that other ECMO meta-analyses conducted database searches on PubMed, EMBASE, Cochrane, and so forth, we searched against the PubMed database only[69], due to the following reasons. During the pilot study, we found that this study required quite an inclusive search of keywords for various cardiopulmonary ECMO indications, compared with meta-analyses on a single indication, as manifested by the total number of articles we worked with. In addition, unlike meta-analyses on relative risks and mean differences, a full-text was laboriously required to confidently make a decision to exclude its corresponding article, because the survival analysis is usually not the main topic of the referenced study but typically comprising just one line of hazard ratio information in the result table or one Kaplan-Meier survival curve figure. Nonetheless, we acknowledge that the risk of missing appropriate articles by not searching against multiple databases could have lowered the reliability of our study[70].
   Whenever HRs and their variances were not reported explicitly, we estimated them from the information reported in the studies. Therefore, the significance of the results of the forest plot should have been diminished by our estimates of HR and variances. In further research, reporting numerical hazard ratios explicitly to facilitate later meta-analysis should be encouraged to investigate the mortality associated with ECMO use.







ECMO meta-analysis on hazard ratios: Respiratory failure (Frank, 2020)

Extracorporeal membrane oxygenation meta-analysis of time-to-event data in respiratory failure in adults

In recognition of the benefits of extracorporeal membrane oxygenation (ECMO) [1], clinical outcomes have been the subject of multiple meta-analyses. Respiratory failure incorporates 'oxygenation failure' of acquiring oxygen and 'ventilatory failure' of eliminating carbon dioxide [2], which are, respectively, exemplified to ECMO indications of "acute respiratory disease syndrome" (ARDS) and "hypercapnic respiratory failure" [3, 4]. The controversial efficacy of ECMO on patient mortality in respiratory failure has been statistically assessed by previous meta-analyses based on relative risks [5-9].
   Unlike a hazard ratio (HR), the relative risk does not consider the time to event or censoring and runs the risk of not using all the available information [10]. In other words, with respect to patient mortality, the relative risk between ECMO and non-ECMO patient groups cannot avoid overlooking the critical factor of how ECMO has influenced the timing of each event or patient death over the course of disease progression. In consideration of heterogeneities such as veno-arterial (VA) and veno-venous (VV) types, this present study applies time-to-event data to evaluations of the utility of ECMO in patients with respiratory failure.
   To the best of our knowledge, the present meta-analysis is the first attempt to use time-to-event data to illustrate a forest plot of mortality from the use of ECMO in adult patients, comprising both VA type and a majority of VV type, in respiratory failure of 'oxygenation failure' and 'ventilatory failure', compared against no ECMO group. When confining to only VV-ECMO, significant reduction in mortality was also noted.
   These results should be understood not only in the context of weighing the benefits and adverse effects of ECMO, but also in consideration of patient selection issues. Although the propensity to allocate the ECMO treatment to poor patient condition was not explicitly located in the referenced studies [27-31], the non-ECMO groups were reportedly selected and specified as groups of patients who required no invasive support [33-35]. This discriminate propensity of ECMO allocation appears to reflect the wide recognition of the benefits of ECMO treatments [1] but, at the same time, indicates a patient selection bias issue of a meta-analysis on the retrospective studies. Therefore, in addition to the intrinsic benefits and adverse effects of ECMO treatment, biased allocation of ECMO based on patient conditions as a whole appeared to contribute to the aforementioned results.
   In this regard, the significant reduction in mortality of the ECMO group in the patients with respiratory failure compared with the non-ECMO group is worthy of mention. Although VV-ECMO could avoid the complications of VA-ECMO, such as systemic embolization, arterial trauma, and increased left ventricular afterload [36, 37], even VV-ECMO alone is still associated with risk of haemorrhage [27, 28, 30] and circuit-associated complications [5]. That is, against the known complications of the ECMOs and the patient selection biases that presumably favor the superior outcome in the non-ECMO group, the significantly improved patient outcomes in respiratory failure in the ECMO group is evident. Our result favoring the ECMO group in respiratory failure is consistent with previous meta-analyses for H1N1 pneumonia [7] and ARDS [5]. It can be tentatively proposed that the inclusion of the two RCTs, which is less apt to be influenced by the patient selection bias, may partially contribute to the significant reduction in mortality of the forest plot due to the increased statistical power of the pooled studies. In addition, the majority of ECMO in the referenced studies was veno-venous type, possibly due to the increased likelihood of normal cardiac function in respiratory failure conditions, which enable the more frequent use of VV-ECMO (or only the use of VV-ECMO [30]) and could avoid the complications of VA-ECMO. However, in consideration of numerous possible confounding factors of heterogeneities that may have influenced the mortality results, this hypothesis needs to be enlightened by more meticulous reasoning which unleashes what factors contributed to the positive results of respiratory failure indication.
   In reality, the number of ECMO studies tend to be small compared to those on relative risks, and relevant mortality studies on ECMO were not always explicitly designed to meet one subcategory of respiratory failure classification, such as 'ARDS' and 'acute respiratory failure', strictly and mutually exclusively. Thus, the scope of this current study on respiratory failure comprises mortality of respiratory failure by either 'oxygenation failure' or 'ventilation failure.' In the meanwhile, technically speaking, respiratory failure type III occurs during perioperative periods that can be related to cardiopulmonary ECMO indications, to name a few, of "bridge to lung transplantation" [3, 4]; while respiratory failure type IV results from shock, which can be related to "myocardial infraction-association cardiogenic shock" [3, 4]. Nonetheless, for more focused investigation, this study condenses to the mortality of hypoxemic (type I: oxygenation failure) and hypercapnic (type II: ventilation failure) respiratory failure.
   Although we are aware of the fact that other ECMO meta-analyses conducted database searches on PubMed, EMBASE, Cochrane, and so forth, we searched against the PubMed database only [38], due to the following reasons. During the pilot study, we found that this study required quite an inclusive search of keywords, as manifested by the total number of articles we worked with. In addition, unlike meta-analyses on relative risks and mean differences, a full-text was laboriously required to confidently make a decision to exclude its corresponding article, because the survival analysis is usually not the main topic of the referenced study but typically comprising just one line of hazard ratio information in the result table or one Kaplan-Meier survival curve figure. Nonetheless, we acknowledge that the risk of missing appropriate articles by not searching against multiple databases could have lowered the reliability of our study [39].
   Whenever HRs and their variances were not reported explicitly, we estimated them from the information reported in the studies. Therefore, the significance of the results of the forest plot should have been diminished by our estimates of HR and variances. In further research, reporting numerical hazard ratios explicitly to facilitate later meta-analysis should be encouraged to investigate the mortality associated with ECMO use.
   Based on the time-to-event data of respiratory failure, ECMO comprising both VV and VA types and the VV type alone has shown to provide advantages over alternative therapy. Although VV-ECMO alone on respiratory failure was mainly addressed in this study, future investigation of the efficacy of VA-ECMO alone in respiratory failure may be more informative, due to being a more common modality of ECMO yet with greater complications [5]. The accumulation of ECMO time-to-event data studies in respiratory failure will enable more focused mortality assessments, for example, on ARDS, exclusively.

It is acknowledged that the ECMO technology from 1975 has changed immensely such that mortality may be correlated with the year, which is exemplified in the improved mortality over years in-between 1995 -2000 and 2001 -2004 [32]. For the referenced studies, the meta-regression analysis of the midpoint of the study period versus the hazard ratio (Figure 5) illustrates an insignificance (p-value = 0.8011) and neither positive nor negative correlation (r = 0.0635) in the scope of this study.

  • NIST's Definition: Cloud computing, as defined by NIST (National Institute of Standards and Technology), is a model that provides widespread, easy, and immediate access to a collective pool of configurable computing resources, enabling them to be quickly allocated and released with minimal effort from management or interaction with the service provider. This model is designed to ensure high availability and comprises five key characteristics: broad network access, on-demand self-service, pooled resources with virtualization, rapid scalability, and services measured and metered for use. It is structured around three core service models — Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) — and is deployed through four models: public, private, community, and hybrid clouds.
  • (1) Virtualization to (2) Cloud: Cloud computing and virtualization serve as cornerstone technologies in modern IT infrastructures, with (1) virtualization enabling multiple virtual environments to run on a single physical hardware system through server and application virtualization. VMware exemplifies server virtualization by dividing a physical server into multiple virtual servers, allowing for efficient resource distribution and coexistence of various operating systems on a single server, while application virtualization simplifies deployment by enabling centralized access for multiple users. In contrast, (2) cloud computing expands on virtualization's resource optimization, providing scalable, flexible, and metered computing services over the internet, such as servers, storage, and software. It introduces key features like on-demand self-service, broad network access, and rapid elasticity, distinguishing itself from virtualization by offering a comprehensive service model that includes infrastructure, platform, and software as services, thus facilitating a broader range of IT solutions beyond mere resource efficiency.
  • Unveiling Shadow IT: Shadow IT refers to the use of IT systems, applications, or services without the explicit approval of an organization's central IT department. This practice is particularly prevalent in cloud computing, where the ease of accessing and deploying cloud services enables individuals or departments to bypass traditional IT controls. While shadow IT can foster innovation by allowing users to quickly meet their needs, it also poses significant risks, including security vulnerabilities and compliance issues, due to the lack of oversight and integration with the organization's IT infrastructure. In the context of cloud computing, the unchecked use of shadow IT amplifies these challenges, potentially leading to data breaches and operational inefficiencies as organizations struggle to manage a sprawling, unsecured digital environment.

    In "Neon Genesis Evangelion," the series draws extensively from Jewish religious and mystical traditions, incorporating figures like Lilith and symbols such as SEELE's seven eyes to deepen its narrative complexity. In Jewish tradition, Lilith is a multifaceted figure. The medieval text "The Alphabet of Ben-Sira" describes her as Adam's first wife, created from the same earth and demanding equality, leading to her departure from Eden when Adam refused. This portrayal highlights themes of independence and defiance. Talmudic and Kabbalistic texts often depict Lilith as a night demon or succubus, associated with causing harm to newborns and pregnant women, emphasizing her role as a figure of fear and danger. Modern feminist interpretations reclaim Lilith as a symbol of female empowerment and liberation, celebrating her refusal to be subservient as an assertion of her rights and independence.

    In Evangelion, Lilith is depicted as the progenitor of humanity, crucified in the depths of NERV headquarters and central to the Human Instrumentality Project. This aligns with the idea of Lilith as a mother figure but places her at the heart of a scientific and existential quest for human evolution and unity. Combining her divine aspects as a source of life with her darker, demonic traits, Evangelion reflects her duality as a figure of creation and destruction. Lilith's involvement in the Human Instrumentality Project, which aims to merge all human souls into a single consciousness, ties into Kabbalistic ideas of achieving divine unity, underscoring themes of autonomy, transformation, and the potential for catastrophic consequences.

    SEELE's symbol of seven eyes, deeply rooted in Jewish mysticism, further emphasizes these themes. This symbol originates from the Bible and Kabbalistic traditions, notably in the Book of Zechariah (4:10), which mentions, "These seven are the eyes of the LORD, which range throughout the earth," signifying divine omniscience and vigilance. In Kabbalah, the seven eyes are associated with the seven lower Sephirot on the Tree of Life, representing divine attributes governing creation. SEELE's use of this symbol reflects their aspiration for god-like knowledge and control over humanity, highlighting their omnipresence and influence through the Human Instrumentality Project.

    The series also draws upon Jewish angelology and mythology, portraying Angels (Shito) with names and characteristics rooted in Jewish and Christian traditions. In Jewish tradition, angels are divine messengers fulfilling roles such as protection, guidance, and executing divine will. However, in Evangelion, Angels are depicted as both divine beings and existential threats to humanity, reflecting their dual nature in Jewish mysticism as agents of both judgment and destruction. For example, Ramiel, meaning "Thunder of God" in Jewish apocryphal texts, represents divine judgment. Ramiel is depicted as a geometric octahedron with a powerful particle beam resembling thunder or lightning, symbolizing overwhelming divine retribution. Zeruel, translating to "Arm of God," symbolizes might and divine retribution. In the series, Zeruel's humanoid form with extendable, blade-like arms culminates in a pivotal battle where Evangelion Unit-01 assimilates Zeruel's arm, symbolizing the merging of human and divine attributes and embodying the struggle to harness immense, divine power.

    The hierarchy and nature of Angels in Evangelion echo Kabbalistic themes, where angels are manifestations of divine energy and cosmic principles. The concept of A.T. Fields (Absolute Terror Fields) parallels the spiritual barriers in Kabbalistic cosmology, representing the separation between the divine and human. The Human Instrumentality Project's goal of uniting all human souls into a single consciousness mirrors the Kabbalistic pursuit of returning to an undivided divine state, reflecting SEELE's plan to dissolve individuality into a collective whole. Through these elements, "Neon Genesis Evangelion" intertwines Jewish religious motifs, exploring themes of divine power, human ambition, and the quest for transcendence, grounding its narrative in a rich and multifaceted mythological framework.

Arrested Development in Rebuild Evangelion and The Tin Drum

Arrested development—the cessation of physical or emotional growth—serves as a profound narrative device that explores the complexities of human experience in tumultuous times. Both Hideaki Anno's Rebuild Evangelion series and Günter Grass's The Tin Drum employ this motif through their protagonists, Shinji Ikari and Oskar Matzerath, who remain physically unchanged while the world around them undergoes dramatic transformations. By examining these works within their historical contexts—post-economic bubble Japan and war-torn Europe—we gain deeper insights into themes of alienation, responsibility, personal growth, and the struggle for identity amid societal upheaval.

  1. Rebuild Evangelion Series

    The Rebuild Evangelion series, particularly the films released from 2007 to 2021, reflects Japan's grappling with economic stagnation following the burst of the bubble economy in the early 1990s. This period, known as the "Lost Decade," was marked by financial instability, unemployment, and a crisis of national identity. Director Hideaki Anno channels these anxieties into a narrative that delves into existential dread, the search for meaning, and the challenges of communication in a disconnected society.

    The story centers on Shinji Ikari, a 14-year-old boy recruited by his estranged father, Gendo Ikari, to pilot a biomechanical robot called an Evangelion (Eva) to combat mysterious entities known as Angels threatening humanity. After triggering a catastrophic event called the near Third Impact, Shinji awakens 14 years later in Evangelion: 3.0+1.0 Thrice Upon a Time, only to find that he has not aged due to the "Curse of Eva." His former allies, including Asuka Langley Shikinami and Rei Ayanami, have grown older and more distant. Shinji's isolation intensifies as he struggles to understand his place in a world that has moved on without him.

    • Shinji Ikari: A sensitive and introspective teenager burdened by his father's expectations and his role in global events he barely comprehends.
    • Gendo Ikari: Shinji's father, whose cold and distant demeanor masks his own grief and obsession with reuniting with his deceased wife, Yui Ikari.
    • Asuka Langley Shikinami: Once Shinji's fiery and competitive comrade, Asuka has aged during Shinji's absence. Her experiences reflect the harsh realities of survival and responsibility.
    • Rei Ayanami: A mysterious girl who is later revealed to be a clone created from Shinji's mother, Yui Ikari. Rei represents a platonic and maternal connection for Shinji.
    • Mari Illustrious Makinami: An enigmatic pilot who offers Shinji a path toward healing and acceptance.
  2. The Tin Drum

    Published in 1959, The Tin Drum is a seminal work of post-war German literature that captures the moral and social disintegration of Europe during World War II. Set in Danzig (now Gdańsk, Poland), the novel follows Oskar Matzerath, who decides at the age of three to stop growing as a protest against the absurdities and moral failures of the adult world. Armed with his tin drum and a glass-shattering scream, Oskar witnesses the rise of Nazism, the horrors of war, and the complexities of human nature from the perspective of a perpetual child.

    Oskar's relationships are central to his narrative. His mother, Agnes Matzerath, is caught in a love triangle between her husband, Alfred Matzerath, and her cousin, Jan Bronski. After Agnes's death, Oskar becomes infatuated with Maria Truczinski, a young woman who marries Alfred following Agnes's demise. Despite being his stepmother, Maria becomes Oskar's lover, complicating his understanding of love and morality.

    • Oskar Matzerath: A self-proclaimed eternal child who uses his stunted growth as both a shield and a weapon against the adult world's corruption.
    • Alfred Matzerath: Oskar's presumptive father, representing the conventional adult world that Oskar rejects.
    • Jan Bronski: Oskar's suspected biological father, whose presence introduces complex dynamics into Oskar's understanding of family and identity. Jan represents a more authentic and compassionate aspect of adulthood, contrasting with Alfred's conventionality. This ambiguity regarding Oskar's paternity adds depth to his rebellion against adult hypocrisy, as he grapples with conflicting emotions and loyalties.
    • Maria Truczinski: A young shop assistant who becomes both Oskar's stepmother and lover, embodying the complexities of love and desire in a chaotic world.

  -   Arrested Development as Resistance and Pathway to Growth

    Shinji Ikari, from Rebuild Evangelion, and Oskar Matzerath, the protagonist of Günter Grass's The Tin Drum, epitomize profound isolation amid rapidly changing worlds. Both halt their physical growth as a defense mechanism against the overwhelming complexities and moral failings they perceive in their societies. Their physical stagnation intensifies their disconnection from peers and society, serving as a catalyst for their internal struggles with responsibility, innocence, and the search for meaning.

    Shinji's Social Context: The Lost Decade and Economic Stagnation

    While Neon Genesis Evangelion is often viewed through a post-apocalyptic lens, its narrative is deeply rooted in the real-world context of Japan's "Lost Decade." This period, following the burst of the bubble economy in the early 1990s, was marked by economic stagnation, unemployment, and a pervasive sense of uncertainty. Shinji's personal struggles mirror these broader societal issues, reflecting the isolation and crisis of purpose experienced by many in Japan during this time.

    The economic downturn influences the environment in which Shinji operates, adding layers to his sense of alienation and responsibility. As traditional social structures falter, so does the social fabric, exacerbating his internal conflicts. The indifference he perceives in the world around him highlights the difficulty of finding meaning amid widespread societal disillusionment.

    1. Impact on Relationships: The economic stagnation affects Shinji's relationships, making them more strained and complex. Characters like Asuka Langley Shikinami and Kensuke Aida represent shifting social dynamics and the redefinition of personal connections in a changing society. Asuka's cohabitation with Kensuke can be seen as a metaphor for these shifts, illustrating how economic and social pressures reshape relationships.
    2. Search for Meaning: The "Lost Decade" fosters a sense of existential dread, a theme central to Shinji's character development. His journey toward acceptance and growth is intertwined with a broader societal quest for stability and purpose. The weight of piloting the Evangelion amidst a collapsing economy underscores his struggle to find personal meaning while bearing an immense responsibility he feels unprepared for.

    Oskar's Social Environment: War and Moral Decay

    Oskar Matzerath grows up during the rise of Nazism and the turmoil of World War II, witnessing firsthand the moral decay and atrocities of the era. The chaos and destruction he observes reinforce his desire to remain a child, shielding himself from the corrupt and violent adult world. His physical stagnation becomes a form of protest against the absurdities he sees in adults and a means to preserve his sense of self amid societal collapse.

    As the war ends and society attempts to rebuild, Oskar recognizes the need to adapt. The societal upheavals force him to confront the futility of his initial rebellion. His relationships with characters like Maria Truczinski expose him to adult emotions and responsibilities, challenging his resistance to growth. The post-war environment pushes Oskar toward a reluctant acceptance of adulthood and its accompanying complexities.

    The Tension Between Innocence and Responsibility

    Despite their youthful appearances, both Shinji and Oskar are thrust into adult roles that demand them to grapple with moral complexities beyond their perceived innocence. This tension between the semblance of childhood and the weight of adult responsibilities highlights their internal conflicts and the burdens placed upon them by circumstances beyond their control.

    1. Shinji Ikari: Thrust into the role of an Eva pilot, Shinji bears the heavy responsibility of saving humanity from existential threats posed by mysterious entities known as Angels. This immense burden forces him to make decisions he feels unprepared for, highlighting the conflict between his introspective, hesitant nature and the demands placed upon him. His struggle is emblematic of a generation facing a loss of direction and purpose, mirroring the societal challenges of Japan's "Lost Decade."
    2. Oskar Matzerath: While maintaining the physical appearance of a child, Oskar engages in complex and morally ambiguous relationships that challenge traditional notions of innocence. His involvement with Maria Truczinski, his stepmother and lover, and his affair with Roswitha Raguna push the boundaries of conventional morality. These interactions expose the darker aspects of his psyche and illustrate the intricate moral landscape he navigates. Oskar's experiences emphasize the burdens of responsibility and the loss of innocence, underscoring the impact of war and societal decay on the individual psyche.

    Integration of Social Contexts and Personal Journeys

    The transformative worlds in which Shinji and Oskar exist are not just backdrops but active forces that shape their identities and choices. Their arrested development is a direct response to the overwhelming pressures of their environments—a Japan grappling with economic despair for Shinji, and a Germany descending into fascism and war for Oskar.

    In Shinji's case, the economic stagnation and the resulting societal malaise intensify his feelings of isolation. The lack of familial support, particularly from his father Gendo Ikari, compounds his struggle. The disintegration of social bonds reflects the broader disconnection felt during the "Lost Decade," making Shinji's internal battles a microcosm of national despair.

    For Oskar, the moral decay of Nazi Germany and the horrors of World War II validate his refusal to join the adult world. His tin drum becomes a symbol of protest and a means to assert control in a world that seems beyond redemption. The post-war attempt to rebuild society forces Oskar to confront the limitations of his perpetual childhood, ultimately pushing him toward growth.

    Confronting Alienation and Embracing Growth

    Both protagonists eventually recognize that their isolation and refusal to grow are unsustainable in their transforming worlds. Their journeys toward accepting responsibility and embracing growth are fraught with internal and external challenges but signify crucial steps in their development.

    Shinji's interactions with characters like Mari Illustrious Makinami and Kaworu Nagisa help him process his trauma and understand the broader implications of his actions. His eventual decision to dismantle the Evangelion system represents a break from his cycle of isolation and a move toward emotional maturity. By reconciling with his father and choosing to live independently of the Eva, Shinji signifies his readiness to engage with the world on his own terms.

    Similarly, Oskar's decision to resume physical growth after deliberately stunting it reflects his reluctant acceptance of adulthood. The deaths of key figures like his presumed father Alfred Matzerath and the disillusionment following the war force him to confront the realities he sought to avoid. By engaging with the complexities of the adult world, Oskar begins to navigate new responsibilities, signaling personal growth amidst societal reconstruction.

Galaxy Express 999 (1981)

  -   Appreciating Life Through the Lens of Mortality

  -   Decoding the Names

    In both "Galaxy Express 999" and "Snowpiercer," the exploitation of young people to support and maintain their respective systems is a central theme, illustrating the dark consequences of societal inequality. In "Galaxy Express 999," children are lured by the promise of immortality through mechanical bodies, only to be dehumanized and reduced to mere components within an oppressive system controlled by the elite. Similarly, "Snowpiercer" depicts a grim reality where children from the lower-class tail section are used as living components to keep the train's engine running, ensuring the survival and comfort of the upper classes. Both narratives highlight severe class divisions and the sacrifice of the vulnerable to sustain the privileged, emphasizing the dehumanizing effects of such exploitation. The use of children as expendable resources underscores the brutality of these dystopian societies, where the elite's comfort comes at the expense of the young and powerless, vividly portraying themes of class struggle and dehumanization.

    In the movie "In Time," the importance of a limited lifespan is highlighted through a futuristic society where time itself becomes the ultimate currency, and the rich can live indefinitely while the poor struggle to earn enough time to survive each day. This stark inequality underscores how the value of time can be distorted when it can be bought and sold. People with nearly unlimited time often waste it on frivolous activities, squandering their endless days because they no longer perceive time as precious. This lack of a finite endpoint leads to existential ennui, with lives feeling directionless and void of meaning. The film emphasizes that mortality provides a crucial sense of urgency and significance to our actions. It conveys that, in reality, people have enough time to live fulfilling lives if they prioritize and manage their time effectively. By focusing on quality over quantity and embracing mindful living, individuals can find contentment and purpose, highlighting that even with a limited lifespan, people can make the most of the time they have, in stark contrast to the aimless existence of those who can live forever.

Chungking Express (1994): A Metaphor for Hong Kong’s Transition

The Hong Kong handover on July 1, 1997, marked a pivotal moment in the city's history, symbolizing its transition from British colonial rule to Chinese sovereignty. Wong Kar-wai's Chungking Express subtly mirrors this political and emotional shift through its omnibus format, which weaves two parallel stories of heartbreak, emotional recovery, and reconnection. These narratives reflect Hong Kong’s own journey during the handover, as the characters deal with loss and transition, symbolizing the city's anxiety about its uncertain future. A key metaphor in the film is the cans with expiration dates, which represent the inevitability of time and change. Much like the expiration dates signal the end of something preserved, Hong Kong’s colonial period had a definitive end date. Officer 223’s fixation on the cans highlights his struggle to let go of the past, mirroring Hong Kong’s broader concerns about its future under Chinese rule. Though 223 and 663 act as policemen, symbolizing the city’s stability amid chaos, both officers are consumed by personal heartbreak, reflecting the fragility beneath Hong Kong’s outwardly stable façade during the transition.

In the first part of the film, the woman in the blonde wig (Brigitte Lin) represents Hong Kongers with complex ties to the West, embodying the morally ambiguous and exploitative nature of colonial relationships. Her involvement with Western men and her role in the drug trade symbolize the darker side of British rule, particularly the opium trade, which devastated China. The blonde wig she wears reflects her attempt to assimilate into Western culture, much like Hong Kong adopted many British influences during the colonial period. Her decision to kill the white drug boss and discard the blonde wig symbolizes a rejection of Western control and a reclaiming of her true identity, mirroring Hong Kong’s desire to move beyond its colonial past. Officer 223’s love for the woman, despite her criminal past, serves as a metaphor for Hong Kong’s acceptance and reconciliation with its complex history. His affection after she sheds her ties to the West illustrates that Hong Kong cannot fully separate itself from its colonial legacy, even as it strives to embrace a new future under Chinese sovereignty.

In the second part of the film, Officer 663, representing Hong Kong, finds himself between two women, each symbolizing a different future. His ex-girlfriend, a flight attendant, embodies the Hong Kongers who sought to leave for Britain during the handover. The chef’s salad, which she initially chooses, represents mainland China, symbolizing its complexity and diversity. The varied ingredients of the salad reflect China’s vastness and the multifaceted influences expected to shape Hong Kong after the handover. However, she ultimately chooses fish and chips, representing how some Hong Kongers held onto their Western ties, even as the city’s future moved toward China.

In contrast, Faye (Faye Wong) symbolizes the Hong Kongers who adapted to the new political reality under Chinese rule. Her practical, unpretentious nature contrasts with the ex-girlfriend’s more polished Western demeanor, reflecting a grounded, forward-looking approach. Faye’s quiet, unnoticed actions, such as cleaning 663’s apartment, metaphorically represent the gradual changes occurring as Hong Kong transitioned into Chinese sovereignty. By removing the remnants of the ex-girlfriend (Britain), Faye symbolizes Hong Kong’s effort to let go of its colonial past and embrace a future with China, even if the changes were subtle and not immediately apparent. Unlike the ex-girlfriend, Faye stays and becomes more involved in 663’s life, symbolizing mainland China’s growing influence in Hong Kong’s future. Her actions, though uninvited, reflect China’s gradual role in reshaping Hong Kong’s political and cultural identity, while the city still maintains elements of its distinctiveness under the "one country, two systems" framework. Faye’s attachment to the song “California Dreamin’” reflects her yearning for freedom and escape, mirroring the fantasies of many Hong Kongers who considered leaving for the West. However, like Hong Kongers who chose to remain, Faye ultimately chooses to stay, facing her future under Chinese sovereignty. Her connection to the song symbolizes the dream of escape, but her decision to stay reflects the reality of Hong Kong’s transition, as the city navigates its new identity while holding onto hopes for personal and collective freedom.

Finally, the acts of washing the woman’s shoes and massaging Faye’s shin serve as symbolic acts of reconciliation for Hong Kong. Officer 223’s act of washing the shoes reflects Hong Kong’s attempt to cleanse and reconcile with its Western-influenced identity, while 663’s massage of Faye’s shin symbolizes Hong Kong’s ability to nurture those who stayed and embraced the city’s future with China. These gestures capture Hong Kong’s acceptance of its complex history and its support for those who chose to stay, despite the uncertainties brought by the handover. Since the 1997 handover, Hong Kong’s future and California, symbolized in Faye’s beloved “California Dreamin’” as places of freedom and opportunity, have not unfolded as optimistically as Wong Kar-wai or others might have envisioned.


Digital Aristotle in the Age of AI

Steve Jobs: "Do you know who Alexander the Great’s tutor was for about 14 years? You know, right? Aristotle. When I read this, I became immensely jealous. I think I would have enjoyed that a great deal. Through the miracle of the printed page, I can at least read what Aristotle wrote without an intermediary. Maybe if there's a professor, they can add to that, but at least I can go directly to the source material. That, of course, is the foundation upon which our Western civilization is built. But I can’t ask Aristotle a question. I mean, I can, but I won’t get an answer. So my hope is that someday, in our lifetimes, we can create a tool of a new kind—an interactive kind. My hope is that when the next Aristotle is alive, we can capture the underlying worldview of that Aristotle in a computer, and someday, a student will not only be able to read the words Aristotle wrote but also ask Aristotle a question and get an answer. That’s what I hope we can do."

- from Steve Jobs' 1985 speech at Lund University, Sweden

    }
    

Day 10: December 18, 2024

Implications


Day 11: December 19, 2024


  1. Visual Studio Code

    Note: Visual Studio Code, sometimes referred to as VS Code, is a cross-platform code editor available for Windows, macOS, and Linux. By contrast, Microsoft’s Visual Studio is a separate integrated development environment primarily aimed at Windows.

    • Inline Autocomplete and Real-Time Code Fixes

      When working on a Python script, inline suggestions appear to complete common code patterns:

      # Example: Simple data processing
      data = [1, 2, 3, 4]
      doubled = [x * 2 for x in data]  # Inline suggestions can offer variable names or transformations
      
      # Real-time error fixes might catch issues like:
      # if dat:  # This might be flagged as an undefined variable
      

      This accelerates coding by proactively highlighting errors—such as referencing undefined variables—and offering quick solutions.

    • “Explain This Function” Feature

      A developer can highlight a complex function in a project:

      def optimize_dataset(dataset):
          """
          Applies various transformations to the dataset
          to ensure optimal performance for ML models.
          """
          cleaned = [record.strip().lower() for record in dataset if record]
          unique_items = list(set(cleaned))
          return sorted(unique_items)
      

      The AI tool then generates a plain-language explanation, clarifying each step for faster onboarding of new team members.

    • Refactoring Suggestions for Repeated Patterns

      For projects with repetitive code blocks across multiple files, the AI integration can detect duplication and provide automated refactoring prompts. This not only enhances code readability but also maintains consistent design patterns throughout the project.

  2. JetBrains Suite (Including PyCharm)

    JetBrains products—including PyCharm for Python—are cross-platform IDEs known for their comprehensive code analysis and refactoring capabilities.

    • AI-Driven Unit Test Generation

      Consider a Python module for string manipulation:

      # file: string_helper.py
      def reverse_string(input_str: str) -> str:
          return input_str[::-1]
      
      def capitalize_words(sentence: str) -> str:
          return ' '.join(word.capitalize() for word in sentence.split())
      

      AI can generate unit tests automatically:

      # file: test_string_helper.py
      import unittest
      from string_helper import reverse_string, capitalize_words
      
      class TestStringHelper(unittest.TestCase):
          def test_reverse_string(self):
              self.assertEqual(reverse_string("hello"), "olleh")
              self.assertEqual(reverse_string(""), "")
      
          def test_capitalize_words(self):
              self.assertEqual(capitalize_words("hello world"), "Hello World")
              self.assertEqual(capitalize_words("python"), "Python")
      
      if __name__ == '__main__':
          unittest.main()
      

      This feature saves time in writing standard test cases and helps ensure coverage for newly written functions.

    • Smart Debugging and Docstring Assistance

      PyCharm integration can provide docstring templates and suggest clarifications while stepping through breakpoints in debug mode. For instance, while debugging a neural network’s training loop, the AI might suggest improvements to docstrings for clarity:

      def train_model(model, data_loader, epochs=10):
          """
          Trains the model over a specified number of epochs.
          :param model: The neural network model
          :param data_loader: Iterator providing training data
          :param epochs: Number of training epochs (default: 10)
          """
          # AI suggestions can include clarifying parameter types or expected shapes of tensors
          for epoch in range(epochs):
              for batch in data_loader:
                  # training logic...
                  pass
      

      Code suggestions can also reduce debugging time by offering tips for handling edge cases (e.g., empty datasets, GPU availability checks, etc.).

    • Multi-Language Support With Continuous Context

      This functionality allows the AI model to maintain an ongoing context across multiple languages. Developers working on Python backends, Kotlin-based Android modules, or Java-based server code can see consistent recommendations that respect the different language rules and paradigms.

  3. Notion

    • Documentation Summaries

      Large design documents can be condensed into concise bullet points. For instance, a 10-page architecture proposal stored in Notion can be summarized into a few paragraphs, extracting relevant features, dependencies, or performance benchmarks. This ensures that key decision-makers have a clear overview without reading the full document.

    • Task Generation

      A brainstorming page can be instantly converted into an actionable task list, with deadlines and assignments automatically suggested. By associating action items with individuals or teams, the AI can reduce the administrative overhead of transferring information from brainstorming sessions to project management tools.

      # Example Brainstorm
      - Discuss future mobile app features
      - Evaluate cloud providers
      - Plan user testing schedule
      
      # AI-Generated To-Do
      1. Finalize mobile app feature requirements by January 10
      2. Compare AWS, GCP, and Azure pricing by January 15
      3. Schedule user testing sessions for February
      
  4. Apple Notes

ChatGPT Business vs Pro: Key Differences and Comparison (Written November 11, 2025)

ChatGPT Business and ChatGPT Pro are two premium subscription plans offered by OpenAI’s ChatGPT service, each tailored to different needs. Both plans grant access to powerful AI models (including the latest GPT-5 series) and advanced features beyond the free tier, but they differ significantly in usage limits, performance, pricing, and focus. Below is a breakdown of how ChatGPT Business compares to ChatGPT Pro across various aspects.

Aspect ChatGPT Pro ChatGPT Business
Target Users Individual “power users” (e.g. researchers, developers) needing maximum AI capability for personal use. Teams and small organizations (minimum 2 users) needing a collaborative AI workspace with business-grade controls.
Pricing USD $200 per month (per user). Monthly subscription only. Approx. $30 per user per month (or ~$25 with annual billing). Requires 2+ users.
Model Access Includes GPT-5 and exclusive GPT-5 Pro mode (highest reasoning power) without strict limits. Always access top models and new previews. Includes GPT-5 (unlimited “Instant” responses; GPT-5 Pro available in a limited capacity). Access to high-level models but some quotas on the most compute-intensive mode.
Performance & Speed Top priority processing – fastest responses, no slow-downs even at peak times. Designed for heavy continuous use. High performance for all users, with priority over free users. Fair-use policies may throttle extremely heavy usage, but generally fast for normal team workloads.
General Usage Limits Effectively unlimited messages and interactions (subject to reasonable use). No fixed hourly caps on chats, images, or uploads. “Virtually unlimited” day-to-day use of GPT-5 for each user. No strict message cap in normal use; very generous allowances before any temporary throttling.
Deep Research Queries Up to 250 deep research tasks per month. Suitable for extensive automated web research and analysis sessions. Approximately 25 deep research tasks per user per month included (similar to Plus tier). Allows occasional in-depth research; more can be added via extra credits if needed.
Collaboration Single-user only (no sharing). Conversations and custom tools are accessible only by the account owner. Multi-user workspace with shared chat projects and custom GPTs. Team members can collaborate, share prompts/results, and work in a unified environment.
Integration No native integration with company data or apps (user provides context manually). Company Knowledge feature: connect ChatGPT to internal sources (e.g. Slack, Google Drive, SharePoint, GitHub) to answer questions using organizational data.
Advanced Features All Plus features plus more. Early access to new models/features (e.g. experimental agents, GPT-4.5 preview). Advanced voice mode (longer conversations, screensharing) and extended image/video generation (Sora) capabilities. Includes all standard ChatGPT tools (data analysis, browsing, image generation, voice mode, etc.). Also offers Canvas for visual collaboration and Record Mode for auditing chats. Lacks the exclusive experimental previews that Pro receives.
Data Privacy User data is handled under standard terms (model improvement opt-out available, but by default conversations may be used for training). No specialized compliance guarantees. Data is not used for training by default. Offers enterprise-grade privacy: encrypted chats, compliance with GDPR/CCPA, SOC 2 certification, etc. Suited for sensitive business data.
Admin & Support No admin controls (personal account only). Standard support. Admin console for user management (SSO, access controls). Enhanced support for businesses. Option to monitor usage analytics across the team.

I. Purpose and Target Users

ChatGPT Pro is aimed at individual professionals and power users who require the absolute maximum AI capability for their personal use. This plan is suitable for one-person use cases such as an AI researcher, a software engineer, or a content creator who constantly pushes the limits of ChatGPT for complex tasks. It delivers the highest performance and removes most usage constraints, reflecting its focus on users with exceptionally demanding workloads.

ChatGPT Business, on the other hand, is designed for small teams, startups, academic groups, or organizations that want to leverage ChatGPT collaboratively. It is essentially a “team plan” – supporting multiple users in a shared workspace – and emphasizes secure use of ChatGPT within a company setting. The Business plan is ideal for scenarios where several people need to use ChatGPT for work or research while sharing knowledge and maintaining oversight (for example, a research lab or a departmental team in a company).

II. Pricing and Subscription Model

The cost difference between the two plans is significant. ChatGPT Pro is priced at $200 USD per month for a single user. It is an individual subscription with no annual discount (month-to-month only) and is a substantial investment geared towards those who truly need its expanded capabilities.

ChatGPT Business is priced on a per-user basis at roughly $30 USD per user per month (with the rate reduced to about $25 if paid annually). Unlike Pro, Business requires at least two seats, since it is intended for team use. For a small company or group, the Business plan’s cost scales with the number of users. While each individual Business seat is much cheaper than a Pro subscription, it provides a somewhat different feature set aligned with organizational use. Business subscribers can add or remove team members through an admin console, and billing is handled centrally (often with an option for annual billing to save costs).

In summary, Pro is a premium personal plan with a high flat fee for one user, whereas Business is a multi-user plan with lower per-user pricing but meant for collaborative use. The choice may come down to budget and how many people need access: a single researcher might justify $200/month for Pro, while a team of four could use Business at ~$30 each (total $120/month) to share AI resources more economically.

III. Model Access and Performance

  1. Model Availability and Quality

    ChatGPT Pro provides unrestricted access to all top-tier models. This includes the standard GPT-5 (used for most queries) as well as the special GPT-5 “Pro” reasoning mode. The GPT-5 Pro mode is an enhanced version of the model that uses more computational power to tackle extremely complex or nuanced prompts with greater accuracy. Pro subscribers have this highest-quality mode at their disposal whenever needed, effectively granting them the most capable AI responses available on the platform. Additionally, Pro users often receive early access to new model versions or experimental models (for example, being able to try preview versions like GPT-4.5 or other research models) that are not available on lower tiers.

    ChatGPT Business also includes the latest GPT-5 model for all users in the workspace, ensuring high-quality answers. Business users can utilize GPT-5 in its normal modes freely and even have access to GPT-5 Pro mode, but in a limited fashion. In practice, the Business plan allows only a small number of GPT-5 Pro mode uses (a handful of high-compute queries per month, e.g. around 15) per user. This means Business users can invoke the maximum reasoning power occasionally for critical tasks, but they cannot rely on it constantly in the way a Pro subscriber can. Aside from that cap on the Pro mode, Business users still get excellent output quality using GPT-5’s other modes (“Instant” and “Thinking” modes for quick answers vs. deeper reasoning). Both plans support large context windows for input and output (tens of thousands of tokens), so they can handle long documents or transcripts, but Pro users have fewer restrictions on intensive model usage.

  2. Speed and Priority

    Performance-wise, ChatGPT Pro is optimized for the fastest and most consistent response times. Pro subscribers receive priority server access, meaning their queries are processed with top priority even during peak usage periods. This results in lower latency and reliable high speed, which is crucial for users who may be iterating quickly or working in real-time scenarios. Even when using computationally heavy modes, Pro users experience minimal slow-downs because the plan allocates the necessary resources to maintain performance.

    ChatGPT Business users also enjoy strong performance, but the priority is balanced among the team and within fair use limits. In general, Business plan users will experience fast responses (much faster than free users and without the severe rate limits of the free tier). During typical operation, a Business user’s experience is comparable to Plus (priority access) or better, so latency is low for most queries. However, because the Business plan supports multiple users and has “fair use” guardrails, extremely heavy usage by one team member (or across the team) might encounter some throttling. For instance, if a user tried to send an extraordinarily high volume of requests in a short time, the system might temporarily slow down that user’s access to maintain system stability. In regular use cases, this is rarely an issue – effectively, Business provides high throughput for each user, but does not promise the absolute unconstrained access that Pro does for an individual.

    Overall, Pro guarantees the highest performance per user, whereas Business provides excellent but shared performance – adequate for almost all teamwork needs, though not specifically tuned for a single user’s maximum throughput in the same way Pro is.

IV. Usage Limits and “Deep Research” Capability

  1. General Usage Allowances

    With ChatGPT Pro, usage limits are largely removed for the subscriber. Pro users have unlimited regular chats and messages, meaning there is no fixed cap such as an hourly or daily message limit on using GPT-5 or other models in normal mode. They can also upload files, generate images, or use other tools at will without worrying about quickly hitting a quota. All usage is still subject to OpenAI’s fair use and abuse prevention policies, but in realistic terms a single person is unlikely to exceed these generous limits in normal use. This freedom enables power users to integrate ChatGPT Pro deeply into their workflow (for coding, writing, analyzing data, etc.) with continuous, intensive usage.

    ChatGPT Business provides very high, but not infinite, usage allowances for each user. In practical terms, each Business user can send virtually unlimited messages to GPT-5 as long as the usage remains human-driven and within normal bounds. Unlike the free tier (which might only allow a few messages before pausing) or the Plus tier’s former limits, Business users do not face strict caps like “N messages per hour” for standard queries – the plan is designed to allow seamless use in a work environment. However, if a team member were to use ChatGPT in an automated or extraordinarily heavy manner (for example, hundreds of rapid-fire requests), the system’s fair use guardrails might temporarily slow down that user’s access to ensure stability for others. Importantly, the Business plan also includes a shared pool of usage in some advanced features (like a limit on how many concurrent “Thinking” mode tasks can run at once) to distribute resources among team members. In everyday use, teams will find the Business plan generous – most normal productivity or research activities will not hit any limits.

    It’s also worth noting that both plans allow usage of other tools like image generation or file analysis. ChatGPT Pro, by virtue of its “unlimited” nature, lets a user generate a large number of images or analyze many files without a hard cap (subject again to fair use). Business users can likewise use these features freely, but the allowances might be effectively partitioned per user or per workspace (ensuring, for example, that one user doesn’t consume all of the team’s capacity if such a scenario applies). In summary, Pro offers an individual the freedom to use ChatGPT heavily all day, whereas Business offers each team member extensive usage freedom suitable for typical professional workloads.

  2. Deep Research Tasks

    Where the difference becomes particularly pronounced is in Deep Research and similar agent-driven tasks. ChatGPT Pro includes a much higher allotment for these intensive research queries – on the order of 250 deep research queries per month for a Pro subscriber. This means a Pro user can initiate complex automated research sessions (each of which might take the AI many minutes and multiple browsing steps to complete) numerous times a month, making it ideal for conducting frequent in-depth analyses (for example, doing a detailed literature review or market research report every workday).

    ChatGPT Business includes access to the Deep Research feature as well, but at a more modest level: typically around 25 deep research queries per month for each user (the same base allowance as the ChatGPT Plus plan). This is sufficient for occasional deep dives – for instance, a team member can run a couple of extensive research tasks per week. If the team’s needs exceed this default, the Business plan offers flexibility to purchase additional capacity or credits to extend the usage of such features. In practice, Business teams can plan their deep research usage (perhaps assigning heavy research tasks to specific team members or scheduling them) to stay within the included limits, whereas a Pro user has the freedom to run these tasks far more frequently without extra cost.

    Additionally, agent-based functionalities (like the “ChatGPT agent” that can execute multi-step actions or the Code Interpreter/Advanced Data Analysis tool) follow a similar pattern: Pro users get the maximum or extended limits (for example, more steps or longer durations for agent tasks), while Business users have generous but lower default limits aligned with standard use. Pro also benefits from higher concurrency – a Pro user can, for instance, generate multiple images or run multiple tasks simultaneously at a faster rate than a Business plan user might be allowed to. However, such differences are mostly relevant only under very heavy usage scenarios.

    In summary, for Deep Research and other high-compute features, ChatGPT Pro offers roughly ten times the allowance of the Business plan per user, reflecting its orientation toward intensive single-user workloads. Business provides enough capability for thorough research on a periodic basis, which for many teams is sufficient, but it is intentionally more limited than Pro to distribute resources across multiple users.

V. Features and Workspace Tools

  1. Collaboration and Sharing

    As an individual subscription, ChatGPT Pro does not offer any built-in collaboration features — everything (conversations, results, custom GPTs) is tied to the single user’s account. If a Pro user wants to share outcomes with others, they would need to manually copy content or use external means, as the platform doesn’t natively support multi-user sharing within the interface.

    ChatGPT Business, however, is fundamentally collaborative. It provides a shared workspace where multiple approved users in the organization can work with ChatGPT and see collective content (subject to permissions set by the admin). For example, the Business plan allows sharing of chat threads or results among team members so that one person’s interaction with ChatGPT can be visible and continued by another if needed. It also supports shared projects and tasks: team members can jointly develop prompts or custom GPTs and keep them within the company workspace. This collaborative environment makes it easier for a team (say, a group of researchers or a content team) to build on each other’s AI-assisted work and maintain consistency. There are also administrative controls to manage this collaboration – an admin can assign roles, ensure certain data is kept private, or monitor usage across the team.

  2. Integration with Company Data

    One of the standout features of ChatGPT Business is the ability to integrate with enterprise data sources through what OpenAI calls “Company Knowledge.” This feature allows the Business workspace to connect ChatGPT to tools like Slack, Google Drive, SharePoint, GitHub, and other internal databases or knowledge bases. Once connected, users can ask ChatGPT questions and get answers that incorporate information from the organization’s own documents and resources – all within the ChatGPT interface. For example, an employee could query “Summarize our Q3 marketing plan” and the model could retrieve the relevant internal document (because it has access through the integration) and produce an answer specific to that document. This is extremely useful for productivity in a business setting and helps tailor the AI’s output to the context of the organization.

    ChatGPT Pro does not have any native feature to connect to private company data or external apps. It operates on the information provided by the user in each session and its built-in training data. A Pro user can manually upload files or paste text for ChatGPT to analyze, but they cannot set up persistent integrations to, say, automatically draw on a corporate Google Drive. In essence, Pro is sandboxed to the user’s inputs and the public web, whereas Business can be woven into a company’s knowledge ecosystem (with proper security and permissions).

  3. Advanced and Exclusive Features

    Beyond collaboration, ChatGPT Pro includes some exclusive or expanded features mainly oriented toward cutting-edge use and early adoption of new capabilities. Pro users are often the first to receive beta features or experimental tools OpenAI is rolling out. For instance, if OpenAI is testing a new multimodal generator or an advanced coding agent, Pro subscribers might get a “research preview” toggle to try it out, whereas Business accounts might not enable such experimental features until they are officially supported. An example is the early access to an “Operator” or enhanced Codex agent – Pro users get to try these innovations earlier, aligning with the expectations that Pro users want the very latest technology.

    In terms of multimedia and interactive features, ChatGPT Pro extends the limits. It offers Advanced Voice Mode, meaning a Pro user can have longer voice conversations, possibly even initiate screen sharing or use video-based features as they become available. Pro users also get extended Sora video generation capabilities: Sora is ChatGPT’s text-to-video tool, and on Pro one can generate longer or higher-resolution video snippets with higher monthly limits (suitable if someone is using AI to create video content or prototypes). In contrast, ChatGPT Business includes voice and Sora access, but typically with more conservative limits — enough for basic usage or demos in a team context but not as much as Pro which could be used to produce more polished outputs at scale.

    ChatGPT Business has its own set of specialized features for productivity. For instance, Business workspaces include a “Canvas” feature, which acts as a collaborative visual space or whiteboard where teams can organize information or brainstorm with the help of AI. They also have “Record Mode,” a feature meant for compliance and auditing, which can keep logs of AI interactions for review. These features are not present in the Pro plan (since an individual doesn’t need an admin audit trail of their own usage or a shared canvas). Moreover, Business users can create workspace-wide custom GPTs – shared AI personas or tools fine-tuned on company data – which then become available to everyone in the organization’s ChatGPT workspace. Pro users can also create custom GPTs, but only for personal use; Business enables an organization to build a repository of custom AI assistants relevant to their domain.

    In summary, Pro focuses on maximizing and enhancing the AI capabilities for a single expert user (with things like cutting-edge model access and expanded media generation), while Business focuses on integrating AI into a team’s workflow (with features for sharing, integrating company data, and maintaining oversight). Both plans share a baseline of powerful ChatGPT functionalities; the differences lie in these additional layers of either individual-centric enhancements or collaboration-centric tools.

VI. Data Privacy and Security

Security and privacy are crucial considerations for many users, especially businesses and researchers handling sensitive data. Here, ChatGPT Business distinguishes itself with stronger guarantees.

By default, ChatGPT Pro operates under the same data usage policy as other individual ChatGPT accounts. This means that unless you manually opt out via the settings, your conversations may be used by OpenAI to further train and improve its models. While OpenAI maintains strict confidentiality and security measures, Pro users’ data is not automatically exempt from training. There is a user-level control to turn off chat history (and thereby not have data used for training), which privacy-conscious Pro subscribers can enable. However, beyond this, Pro does not come with bespoke privacy commitments or compliance certificates – it’s essentially a consumer service, albeit a paid one.

In contrast, ChatGPT Business is built with privacy in mind for organizational use. Data from Business workspaces is not used to train OpenAI’s models by default. OpenAI explicitly commits that the prompts and outputs in a Business (or Enterprise) account are kept out of their training datasets. Furthermore, Business provides enhanced encryption (chats are encrypted at rest on OpenAI’s servers and in transit) and is aligned with various compliance standards such as SOC 2 Type II and ISO 27001 series for information security. This means businesses can be more confident in the confidentiality of their data when using ChatGPT. The Business plan also facilitates compliance with data protection laws like GDPR and CCPA, offering features such as data export and deletion upon request, and giving administrators control over data retention (for example, the ability to set how long chat histories are saved).

Another security aspect is user management and authentication. ChatGPT Business supports SAML single sign-on (SSO) and multi-factor authentication (MFA), allowing integration with a company’s identity management system. This ensures that only authorized employees can access the company’s ChatGPT workspace, and that they can do so with their regular corporate credentials and security policies. Pro accounts do not have these features; access is simply via an individual’s OpenAI login.

Additionally, Business plan admins can monitor usage and set certain restrictions if needed (for instance, disabling the ability to use certain tools if they pose a compliance risk, or reviewing logs for unusual activity). None of these administrative or oversight capabilities are available in Pro, since Pro is not intended for multiple users or governance — it assumes the individual user is self-governing their usage.

In essence, for scenarios requiring stringent data privacy, compliance, and control, ChatGPT Business provides a suitable environment. Academic institutions or companies dealing with proprietary information would lean toward Business or Enterprise plans to ensure their data is handled appropriately. Meanwhile, an individual using Pro must take their own precautions (like turning off data sharing in settings) if they have privacy concerns, but cannot achieve the same level of isolation and contractual assurance that Business offers.

VII. Choosing Between ChatGPT Business and Pro

When deciding between ChatGPT Business and ChatGPT Pro, the choice usually hinges on the intended usage and user base:

ChatGPT Pro is best for an individual expert or power user who needs the full power of ChatGPT without constraints. This plan is ideal if extremely high usage, top model performance, and early access to new features are mission-critical for a single user. For example, an independent AI researcher conducting daily deep analyses, or a developer constantly interacting with the model for complex coding tasks, would benefit from Pro’s unlimited access and superior performance. In academic terms, a solo researcher or analyst who doesn’t need to share the AI with others may find Pro to dramatically boost personal productivity and research capabilities.

ChatGPT Business is the better choice when the goal is to support multiple users or a team in a professional setting. If collaboration, shared knowledge, and data privacy are important – such as in a corporate department, a startup team, or a research group – Business provides a more appropriate framework. Each user still gets strong AI capabilities (comparable to the Plus level or higher), and the team gains the ability to work together with the AI. For example, a small research lab at a university could use a Business workspace to collectively analyze literature or data, with all members accessing the same custom GPTs and datasets securely. Likewise, a business can deploy ChatGPT Business to multiple staff for content creation, customer support drafting, or brainstorming, all while keeping the company’s information safe and centralizing the AI usage under admin oversight.

Finally, budget plays a role: if only one person needs access, the steep cost of Pro might be justified for its capabilities. But if a similar budget could instead cover several Business seats, an organization might get more overall value by enabling AI for multiple people. It comes down to whether maximum power for one user (Pro) outweighs ample power for several users plus teamwork features (Business) for your particular situation.

To summarize these recommendations:

Both ChatGPT Business and Pro provide powerful enhancements over the free or standard Plus plan. ChatGPT Pro delivers an elite, unconstrained AI experience for one, while ChatGPT Business creates a secure, collaborative AI environment for many. The “best” choice depends on whether the use case is an individual power-user scenario or a multi-user collaborative scenario.

V. Service-by-service interpretation

  1. OpenAI ChatGPT Pro

    OpenAI ChatGPT Pro remains closest to the most balanced general-purpose AI platform in the premium personal subscription market. Coding, document writing, image generation, voice, agent mode, deep research, custom GPTs, API automation, and developer ecosystem support are broadly connected. It may not always rank first in every single category, but its strength lies in maintaining high scores across almost every type of task.

    However, structural pressure is also clear. High-performance reasoning, long context, file processing, image generation, and coding agents all consume substantial GPU and power resources. As usage grows, not only revenue but also inference cost grows rapidly, so long-term profitability still requires continued validation.

    Most suitable use: General work, coding assistance, document work, automation, research, and power-user workflows requiring image, voice, and tool usage within one service.

  2. Anthropic Claude Max

    Claude Max has a very strong position in coding, long-form reasoning, document analysis, and enterprise work reliability. In actual developer workflows, Claude Code, long-context handling, response consistency, and code refactoring capability are highly valued. Its strengths are especially clear in reading and modifying complex code, as well as handling long reports and policy documents.

    Its weaknesses are the breadth of its consumer ecosystem and its multimodal and search integration. It does not have the same broad consumer-standard position as OpenAI, nor does it have an operating system, search, email, and document ecosystem comparable to Google.

    Most suitable use: Developers, technical writers, enterprise document analysis, and professional work requiring long-form reasoning.

  3. Google Gemini Ultra

    The core of Gemini Ultra is not only the model itself, but its connection with the entire Google ecosystem. Search, Gmail, Docs, Drive, Slides, Sheets, Meet, Android, Chrome, YouTube, Google Cloud, and TPU infrastructure can all be connected. This structure is highly powerful from a long-term perspective.

    As of May 2026, Google has been moving to strengthen price competitiveness in the premium AI subscription market by lowering Ultra pricing and adding a $100-level Ultra option. Its possession of proprietary TPUs and data centers is a major advantage in inference cost sustainability.

    Its weakness is the perceived naturalness of responses and developer-community preference among some users. Compared with OpenAI or Claude, its conversational feel can seem less natural or more corporate. Nevertheless, from the perspective of long-term platform dominance, it appears to be the most structurally advantaged candidate.

    Most suitable use: Google Workspace-centered work, search-based investigation, multimodal work, and long-term AI usage inside the Google ecosystem.

  4. xAI SuperGrok Heavy

    SuperGrok Heavy has the most distinctive positioning. Rather than being a conventional document assistant, it is strong in real-time internet reactions, X-based public sentiment, memes, political and social flows, and fast atmosphere detection. In real-time capability alone, it is highly powerful.

    However, it has weaknesses in enterprise trust, stability, long-form document handling, and conservative factual reliability. Its response style is forceful, product direction can change quickly, and market concerns remain regarding organizational stability.

    Most suitable use: Real-time internet trends, X-based social reactions, meme and public sentiment analysis, and rapid issue detection.

  5. Perplexity Max

    Perplexity Max is closer to an AI search and research engine than a general-purpose AI assistant. It is strong in finding sources, collecting materials, and quickly scanning papers, articles, and market information. For search-centered work, it can often feel more direct and efficient than ChatGPT Pro or Claude Max.

    However, it is more limited in creative workflows, agent automation, coding productivity, and multimodal platform extensibility. Rather than leading with its own frontier model, it is closer to optimizing the research experience by combining multiple advanced models with search infrastructure.

    Most suitable use: Paper research, market research, source verification, rapid investigation, and search-based knowledge discovery.

VI. Core changes in the current AI market

In 2023 and 2024, the central question in the AI market was “which company has built the smartest model.” In 2025 and 2026, however, the central question has shifted to “which company can control real workflows.” Model performance remains important, but it is no longer sufficient by itself.

  1. Workflow control

    AI is moving beyond the chat window into code editors, document writing, email, browsers, search, meetings, data analysis, and file handling. From this perspective, OpenAI and Google are the strongest. OpenAI has already established broad work habits through ChatGPT, while Google can directly integrate AI into everyday work environments through Workspace and Android.

  2. Ecosystem integration

    From the ecosystem perspective, Google is the strongest. Google owns search, email, documents, drive storage, video, mobile operating system, browser, and cloud infrastructure. OpenAI has a strong developer ecosystem and strong ChatGPT user habits, but it does not directly own an operating system, search platform, or email platform.

  3. Inference cost sustainability

    Long-term profitability for AI subscription services becomes more important as usage increases. Traditional SaaS products often benefit from greater economies of scale as users grow, but generative AI incurs GPU inference cost every time a user asks a question. From this perspective, Google is the most advantaged because it owns proprietary chips and data centers.

  4. Enterprise work penetration

    In enterprise work, Claude Max and OpenAI ChatGPT Pro are both strong. Claude is excellent in stability, long-form processing, and coding consistency, while OpenAI is strong in tool ecosystem and API extensibility. Google has a structure that can naturally penetrate enterprise environments through Workspace and Cloud.

  5. Real-time information and search

    Grok and Perplexity are strong in real-time information, while Gemini and Perplexity are strong in search-based accuracy. ChatGPT has also strengthened search and deep research, but its nature is different from Google or Perplexity, whose core business is search.

  6. Long-term platform dominance

    From the perspective of long-term platform dominance, Gemini appears to have the strongest advantage. The reason is straightforward. Google owns AI models, search, operating system, browser, email, document tools, cloud, video platform, and proprietary chips. This combination is difficult for other competitors to replicate in the short term.

VII. Final judgment

In terms of actual satisfaction for a personal Pro-level subscription, OpenAI ChatGPT Pro remains the strongest “single choice” candidate. It maintains a strong balance across generality, ecosystem, experimental features, developer base, and automation extensibility.

However, the long-term leadership of the overall market should be viewed differently. As the AI market shifts from model performance competition to workflow, ecosystem, infrastructure, and cost-sustainability competition, the structural advantage of Google Gemini Ultra increases. Google can absorb AI into its existing ecosystem even if AI does not succeed as a standalone product, and if AI succeeds at large scale, it can further strengthen Google’s existing platform dominance.

Claude Max has strong staying power as a high-quality tool for coding and enterprise work. If OpenAI is the standard for general-purpose AI platforms, Claude is becoming the strong player in high-trust professional work. For developers and document-centered professionals in particular, Claude Max may feel more practical than ChatGPT Pro in specific workflows.

SuperGrok Heavy has a clear differentiator in real-time capability, but its challenges in stability and enterprise trust are significant. Perplexity Max is best understood not as a direct general-purpose AI platform competitor, but as a very strong supporting platform for search and research workflows.

Record-oriented conclusion: As of May 2026, OpenAI ChatGPT Pro is reasonably viewed as the top overall choice for premium personal AI subscription use. Claude Max is the strongest in coding and long-form reliability. Google Gemini Ultra is the most advantaged in search, multimodal capability, ecosystem integration, infrastructure, and long-term platform dominance. SuperGrok Heavy has specialized strength in real-time internet flows, while Perplexity Max has specialized strength in source-based research.

Therefore, the current market is better understood not as converging toward one absolute winner, but as separating into the following roles.

Role Leading service Interpretation
General-purpose AI work platform OpenAI ChatGPT Pro The most balanced personal Pro-level AI
Professional coding and long-form reasoning Claude Max Strong in developer workflows and enterprise document work
Long-term platform dominance Google Gemini Ultra Combines search, OS, browser, Workspace, and TPU infrastructure
Real-time internet and social media SuperGrok Heavy Strong in X-based latest reactions and public sentiment flows
Search and research Perplexity Max Strong in source-based investigation and material discovery

V. 서비스별 해석

  1. OpenAI ChatGPT Pro

    OpenAI ChatGPT Pro는 개인 고급 구독 시장에서 여전히 가장 균형 잡힌 범용 AI 플랫폼에 가깝다. 코딩, 문서 작성, 이미지 생성, 음성, agent mode, deep research, custom GPT, API 자동화, 개발자 생태계가 폭넓게 연결되어 있다. 특정 한 분야에서 항상 1등이라고 보기는 어렵지만, 거의 모든 작업에서 높은 점수를 유지한다는 점이 강점이다.

    다만 구조적 부담도 분명하다. 고성능 reasoning, 긴 context, 파일 처리, 이미지 생성, 코딩 agent는 모두 GPU와 전력 비용을 많이 소비한다. 사용자가 늘수록 매출뿐 아니라 추론 비용도 빠르게 증가하는 구조이므로, 장기 수익성은 계속 검증되어야 한다.

    가장 적합한 사용: 범용 업무, 코딩 보조, 문서 작업, 자동화, 리서치, 이미지·음성·도구 사용을 한 서비스 안에서 처리하려는 파워유저.

  2. Anthropic Claude Max

    Claude Max는 코딩, 장문 reasoning, 문서 분석, 기업 업무 안정성에서 매우 강한 위치를 가진다. 실제 개발 workflow에서는 Claude Code와 Claude의 긴 문맥 처리, 답변 일관성, 코드 리팩토링 능력이 높게 평가된다. 특히 복잡한 코드를 읽고 수정하거나, 긴 보고서와 정책 문서를 처리하는 작업에서 강점이 뚜렷하다.

    약점은 범용 소비자 생태계와 멀티모달·검색 통합의 폭이다. OpenAI처럼 대중적 AI 표준 위치를 넓게 장악하고 있거나, Google처럼 운영체제·검색·이메일·문서 생태계를 모두 가진 구조는 아니다.

    가장 적합한 사용: 개발자, 기술 문서 작성자, 기업 문서 분석 업무, 긴 reasoning이 필요한 전문직.

  3. Google Gemini Ultra

    Gemini Ultra의 핵심은 모델 자체만이 아니라 Google 전체 생태계와 결합된다는 점이다. Search, Gmail, Docs, Drive, Slides, Sheets, Meet, Android, Chrome, YouTube, Google Cloud, TPU 인프라가 모두 연결될 수 있다. 이 구조는 장기적으로 매우 강력하다.

    2026년 5월 기준 Google은 Ultra 가격을 낮추고 $100급 Ultra 옵션도 추가하면서, 고급 AI 구독 시장에서 가격 경쟁력까지 강화하는 방향으로 움직이고 있다. 자체 TPU와 데이터센터를 보유한 점은 추론 비용 지속가능성에서 매우 큰 이점이다.

    약점은 일부 사용자가 체감하는 답변 자연스러움과 개발자 문화에서의 선호도이다. OpenAI나 Claude에 비해 대화 감각이 덜 자연스럽거나 지나치게 기업적이라고 느껴지는 경우가 있다. 그러나 장기 플랫폼 패권 관점에서는 가장 유리한 후보로 판단된다.

    가장 적합한 사용: Google Workspace 중심 업무, 검색 기반 조사, 멀티모달 작업, 장기적으로 Google 생태계 안에서 AI를 활용하려는 사용자.

  4. xAI SuperGrok Heavy

    SuperGrok Heavy는 가장 독특한 포지션을 가진다. 일반적인 문서 assistant보다는 실시간 인터넷 반응, X 기반 여론, 밈, 정치·사회 흐름, 빠른 분위기 파악에 강하다. 실시간성 하나만 놓고 보면 매우 강력하다.

    그러나 기업 업무 신뢰도, 안정성, 장문 문서 처리, 보수적 정확성 측면에서는 약점이 있다. 응답 스타일이 강하고, 제품 방향이 빠르게 바뀔 수 있으며, 조직 안정성에 대한 시장 우려도 존재한다.

    가장 적합한 사용: 실시간 인터넷 트렌드, X 기반 사회 반응, 밈·여론 분석, 빠른 이슈 감지.

  5. Perplexity Max

    Perplexity Max는 범용 AI assistant라기보다 AI 검색·리서치 엔진에 가깝다. 출처를 찾고, 자료를 모으고, 논문·기사·시장 정보를 빠르게 훑는 작업에 강하다. 검색 중심 업무에서는 ChatGPT Pro나 Claude Max보다 더 직접적이고 효율적인 경우가 많다.

    다만 창의적 workflow, agent 자동화, 코딩 생산성, 멀티모달 플랫폼 확장성에서는 상대적으로 제한적이다. 자체 frontier model을 주도하는 회사라기보다는, 여러 고급 모델과 검색 인프라를 결합해 리서치 경험을 최적화하는 쪽에 가깝다.

    가장 적합한 사용: 논문 조사, 시장 조사, 출처 확인, 빠른 리서치, 검색 기반 지식 탐색.

VI. 현재 AI 시장의 핵심 변화

2023~2024년 AI 시장의 핵심 질문은 “누가 가장 똑똑한 모델을 만들었는가”였다. 그러나 2025~2026년의 핵심 질문은 “누가 실제 workflow를 장악하는가”로 바뀌고 있다. 모델 성능 차이는 여전히 중요하지만, 단독으로는 충분하지 않다.

  1. Workflow 장악력

    AI가 단순 채팅창에 머물지 않고, 코드 편집기, 문서 작성, 이메일, 브라우저, 검색, 회의, 데이터 분석, 파일 처리 속으로 들어가고 있다. 이 관점에서는 OpenAI와 Google이 가장 강하다. OpenAI는 이미 ChatGPT를 통해 범용 업무 습관을 장악했고, Google은 Workspace와 Android를 통해 일상적 업무 환경을 직접 통합할 수 있다.

  2. 생태계 통합

    생태계 관점에서는 Google이 가장 강력하다. Google은 검색, 이메일, 문서, 드라이브, 동영상, 모바일 운영체제, 브라우저, 클라우드를 모두 가진다. OpenAI는 개발자 생태계와 ChatGPT 습관이 강하지만, 운영체제와 검색·이메일 플랫폼을 직접 보유하지 않는다는 약점이 있다.

  3. 추론 비용 지속가능성

    AI 구독 서비스의 장기 수익성은 사용량이 늘어날수록 더 중요해진다. 일반 SaaS는 사용자가 늘면 규모의 경제가 커지는 경우가 많지만, 생성형 AI는 사용자가 질문할 때마다 GPU 추론 비용이 발생한다. 이 관점에서는 자체 칩과 데이터센터를 가진 Google이 가장 유리하다.

  4. 기업 업무 침투력

    기업 업무에서는 Claude Max와 OpenAI ChatGPT Pro가 모두 강하다. Claude는 안정성, 장문 처리, 코딩 일관성에서 우수하고, OpenAI는 도구 생태계와 API 확장성에서 강하다. Google은 Workspace와 Cloud를 통해 기업 환경에 자연스럽게 침투할 수 있는 구조를 가진다.

  5. 실시간 정보와 검색

    실시간 정보는 Grok과 Perplexity가 강하고, 검색 기반 정확성은 Gemini와 Perplexity가 강하다. ChatGPT도 검색과 deep research를 강화하고 있으나, 검색 자체를 본업으로 가진 Google이나 Perplexity와는 성격이 다르다.

  6. 장기 플랫폼 패권

    장기 플랫폼 패권 관점에서는 Gemini가 가장 유리해 보인다. 이유는 단순하다. Google은 AI 모델, 검색, 운영체제, 브라우저, 이메일, 문서도구, 클라우드, 동영상 플랫폼, 자체 칩을 모두 보유하고 있다. 이 조합은 다른 경쟁사가 단기간에 복제하기 어렵다.

VII. 최종 판단

개인 Pro급 구독의 실제 만족도만 놓고 보면, OpenAI ChatGPT Pro는 여전히 가장 좋은 “하나만 고른다면” 후보이다. 범용성, 생태계, 실험 기능, 개발자 기반, 자동화 확장성에서 높은 균형을 유지하고 있기 때문이다.

그러나 시장 전체의 장기 우위는 조금 다르게 보아야 한다. AI 시장이 모델 성능 경쟁에서 workflow, 생태계, 인프라, 비용 지속가능성 경쟁으로 이동할수록 Google Gemini Ultra의 구조적 우위가 커진다. Google은 AI가 독립 제품으로 성공하지 않아도 기존 생태계 안에 AI를 흡수할 수 있고, AI가 크게 성공하면 기존 플랫폼 지배력을 더 강화할 수 있다.

Claude Max는 코딩과 기업 업무의 고품질 도구로서 강한 생존력을 가진다. OpenAI가 범용 플랫폼의 표준이라면, Claude는 고신뢰 전문 업무의 강자로 자리 잡고 있다. 특히 개발자와 문서 중심 전문직에게는 Claude Max가 ChatGPT Pro보다 더 실용적으로 느껴질 수 있다.

SuperGrok Heavy는 매우 강한 실시간성이라는 차별점이 있으나, 안정성과 기업 신뢰도 측면의 과제가 크다. Perplexity Max는 범용 AI 플랫폼 경쟁자라기보다 검색·리서치 workflow에서 매우 강한 보조 플랫폼으로 보는 것이 적절하다.

기록용 결론: 2026년 5월 기준, 개인 고급 구독의 종합 실사용 1순위는 OpenAI ChatGPT Pro로 보는 것이 타당하다. 코딩과 장문 안정성은 Claude Max가 가장 강하다. 검색·멀티모달·생태계·인프라·장기 플랫폼 패권은 Google Gemini Ultra가 가장 유리하다. 실시간 인터넷 흐름은 SuperGrok Heavy, 출처 기반 리서치는 Perplexity Max가 각각 특화 우위를 가진다.

따라서 현재 시장은 하나의 절대 승자로 수렴한다기보다, 다음과 같은 역할 분화로 정리하는 것이 가장 현실적이다.

역할 우위 서비스 해석
범용 AI 업무 플랫폼 OpenAI ChatGPT Pro 가장 균형 잡힌 개인 Pro급 AI
전문 코딩·장문 reasoning Claude Max 개발자와 기업 문서 업무에 강함
장기 플랫폼 패권 Google Gemini Ultra 검색·OS·브라우저·Workspace·TPU 결합
실시간 인터넷·SNS SuperGrok Heavy X 기반 최신 반응과 여론 흐름에 강함
검색·리서치 Perplexity Max 출처 기반 조사와 자료 탐색에 강함

Key quotations on AI, compilers, and programming (Written June 14, 2026)

I. Main quotation from Open Source Summit Korea 2025

  1. AI as another tool, like compilers

    “AI is just another tool, the same way compilers free people from writing assembly code by hand, and increase productivity enormously but didn’t make programmers go away.”

    Status: Reported direct quotation.

    Speaker: Linus Torvalds.

    Context: Dirk Hohndel asked whether AI would significantly affect software development as a career, after mentioning software-developer layoffs and claims that AI makes programmers more productive.

    Reported source: Tim Anderson, “Linus Torvalds is OK with vibe coding as long as it’s not used for anything that matters,” The Register, published November 18, 2025, 13:38 UTC. Source article .

    Event source: Linus Torvalds in conversation with Dirk Hohndel, Open Source Summit Korea 2025, The Linux Foundation, Seoul, South Korea, November 5, 2025, Grand Ballroom. Open Source Summit Korea 2025 archive .

    Primary video source: The Linux Foundation, Keynote: Linus Torvalds, Creator of Linux & Git, in Conversation with Dirk Hohndel .

    Note on wording: The Register’s written version uses “free” and “increase.” The supplied auto transcript renders the same passage as “freed” and “increased.” Both refer to the same answer.

  2. Transcript-style form of the same passage

    “AI is just another tool, the same way compilers freed people from writing assembly code by hand and increased productivity enormously but didn’t make programmers go away.”

    Status: Transcript-style rendering of the same answer.

    Reference: User-supplied auto transcript of Keynote: Linus Torvalds, Creator of Linux & Git, in Conversation with Dirk Hohndel, Open Source Summit Korea 2025.

II. Video source

Video: The Linux Foundation, Keynote: Linus Torvalds, Creator of Linux & Git, in Conversation with Dirk Hohndel .

III. Where the quotation appears in the auto transcript

The supplied auto transcript does not include timestamps. The quotation is therefore located by its surrounding transcript anchors: it appears in the AI-for-code-generation and software-career-impact section, after the discussion of vibe coding and the “last 10%” of software projects.

Position Transcript anchor Why it matters
Immediately before the quotation “Do you think there will be a significant impact on software development as a career?” This shows that the quote is an answer to the question of whether AI will reduce or eliminate software-development careers.
Main quotation “AI is just another tool, the same way compilers freed people from writing assembly code by hand and increased productivity enormously but didn’t make programmers go away.” This is the core comparison: compilers changed programming and greatly improved productivity, but did not eliminate programmers.
Immediately after the quotation “I think AI in the end will be that too, that it’s another tool that allows you to not have to deal with all of the minutia, but it doesn’t make the actual programmers go away.” This continuation confirms that Torvalds is arguing against programmer disappearance, not against AI-assisted code generation.
Closing sentence of the same answer “If anything, it probably makes people more productive, but also opens up whole new areas of development and you actually end up with more software programmers for that reason.” This adds the optimistic part of the argument: productivity gains may create more software activity, not merely reduce headcount.

IV. Additional important quotations from the same Korea 2025 discussion

  1. Maintainer, not programmer

    “For the last almost 20 years I’ve not been a programmer. I’ve been a technical lead and maintainer of the system.”

    Reference: The same Open Source Summit Korea 2025 conversation. This is also reported in The Register article.

  2. Real projects are maintenance

    “All real projects, the real work is in maintenance and ongoing support.”

    Reference: User-supplied auto transcript of the same Linux Foundation keynote recording.

  3. AI is experimental for kernel maintenance

    “We have people who are doing a lot of work in using AI mainly to help maintainers deal with the flow of patches and backporting patches to stable versions.”

    Reference: User-supplied auto transcript; same AI section of the Linux Foundation keynote recording.

  4. AI crawlers as infrastructure disruption

    “AI has been very disruptive to a lot of our infrastructure.”

    Reference: User-supplied auto transcript. The Register also reports Torvalds’s point that AI crawlers have been disruptive to kernel.org infrastructure.

  5. AI-generated security slop

    “We do see bug reports and security notices that are clearly basically made up by people who misuse AI, and it does take resources away from maintainers.”

    Reference: User-supplied auto transcript. The Register article summarizes the same point in its discussion of AI-generated bug and security reports.

  6. Vibe coding as learning, not production

    “Vibe coding may be a horrible, horrible idea from a maintenance standpoint.”

    Status: Reported direct quotation.

    Reference: Linus Torvalds, in conversation with Dirk Hohndel, Open Source Summit Korea 2025, The Linux Foundation, Seoul, South Korea, November 5, 2025. Reported by Tim Anderson, The Register, November 18, 2025. Source article .

  7. Vibe coding can still be useful for newcomers

    “I think it’s a great way for new people to get involved and get excited about computers and get computers to do something that maybe they couldn’t do otherwise.”

    Reference: User-supplied auto transcript. The Register article also describes this as Torvalds’s positive view of vibe coding as an entry point.

  8. The final 10 percent

    “The last 10% is the thing that takes 34 years out of your 35 year project.”

    Reference: User-supplied auto transcript. This line appears immediately before the question about whether AI will affect software development as a career.

  9. AI removes minutiae, not programmers

    “It’s another tool that allows you to not have to deal with all of the minutia, but it doesn’t make the actual programmers go away.”

    Reference: User-supplied auto transcript. This is the continuation of the main compiler analogy.

  10. Productivity may create more software work

    “If anything, it probably makes people more productive, but also opens up whole new areas of development.”

    Reference: User-supplied auto transcript. This follows directly after Torvalds says AI does not make actual programmers go away.

  11. AI becoming ordinary

    “I’m looking forward to the day when AI is less hyped and more like the everyday reality that nobody talks constantly about.”

    Reference: User-supplied auto transcript. The Register also reports this line after the compiler analogy.

  8. Programmers must still understand the result

    “You need to understand not just your prompts, but you need to understand the end result too.”

    Status: Reported direct quotation.

VI. Paraphrase to use with references

  1. Summary sentence, not a direct quotation

    AI can be a powerful productivity tool, much like assemblers and compilers were powerful productivity tools. But productivity tools do not remove the need for programmers, maintainers, judgment, review, debugging, architecture, and long-term responsibility.

    Status: Paraphrase, not a verbatim Torvalds quotation.

    Reference basis: The paraphrase is supported by Torvalds’s compiler analogy at Open Source Summit Korea 2025, reported by The Register; his later AI-and-compilers discussion at Open Source Summit North America 2026, reported by LWN.net and TechRadar; and Linux kernel documentation requiring human responsibility for AI-assisted contributions.

    Links: The Register, November 18, 2025; LWN.net, May 25, 2026; TechRadar, May 21, 2026; Linux kernel documentation: AI Coding Assistants; Linux kernel documentation: Tool-Generated Content.

  2. Safer attribution wording

    Torvalds’s position can be summarized as follows: AI may become a powerful productivity tool, much like assemblers and compilers, but productivity tools do not remove the need for programmers, maintainers, judgment, review, debugging, architecture, and long-term responsibility.

    Status: Recommended wording for explanatory prose. This avoids presenting the summary sentence as a direct quotation.

VII. Linux kernel policy as supporting evidence

The Linux kernel documentation is not the source of the Torvalds quotation, but it supports the same responsibility principle: AI assistance does not remove the human submitter’s duty to understand, review, certify, and defend the contribution.

Policy area Relevant point Source
AI coding assistants AI tools helping with Linux kernel development should follow the standard kernel development process. AI agents must not add Signed-off-by tags, because only humans can legally certify the Developer Certificate of Origin. AI Coding Assistants
Tool-generated content Contributors are expected to understand and be able to defend everything submitted. Maintainers may reject tool-generated changes that the submitter cannot explain. Kernel Guidelines for Tool-Generated Content
