Anti-Personnel Computing (2023)

permalink

Posted: 2025-05-13 08:06:59

The author argues that modern personal computing has become "anti-personnel," designed to exploit users rather than empower them. Software and hardware are increasingly complex, opaque, and controlled by centralized entities, fostering dependency and hindering user agency. This shift is exemplified by the dominance of subscription services, planned obsolescence, pervasive surveillance, and the erosion of user ownership and control over data and devices. The essay calls for a return to the original ethos of personal computing, emphasizing user autonomy, open standards, and the right to repair and modify technology. This involves reclaiming agency through practices like self-hosting, using open-source software, and engaging in critical reflection about our relationship with technology.

In a provocatively titled essay, "Anti-Personnel Computing (2023)," the author, Alexandre Blin, expounds upon a perceived shift in the landscape of personal computing, arguing that it has evolved from a tool primarily empowering individual users to a system increasingly designed to manage and exploit them. Blin posits that the contemporary digital environment, characterized by ubiquitous surveillance, pervasive advertising, and the commodification of personal data, functions as a form of "anti-personnel" technology, subtly yet effectively weaponized against its users.

The author meticulously dissects several key aspects of modern computing that contribute to this purportedly hostile environment. He begins by examining the pervasiveness of data collection, highlighting how seemingly innocuous actions, such as browsing websites or using mobile applications, generate an immense quantity of information about users' habits, preferences, and even their physical locations. This data, Blin argues, is then aggregated and analyzed by powerful entities, from tech giants to governments, to build detailed profiles that can be used for a multitude of purposes, many of which are detrimental to individual autonomy and privacy.

Blin further elaborates on the insidious nature of targeted advertising, which he characterizes as a manipulative force that preys on users' vulnerabilities and desires. He contends that the algorithms driving these advertising systems are meticulously crafted to exploit human psychology, subtly influencing purchasing decisions and shaping consumer behavior. This pervasive influence, he suggests, erodes individual agency and fosters a culture of consumerism.

The essay also delves into the increasingly prevalent phenomenon of surveillance capitalism, the economic system in which user data is the primary commodity. Blin argues that this system inherently incentivizes the collection and exploitation of personal information, creating a feedback loop where companies are constantly seeking new and more intrusive ways to gather data about their users. This dynamic, he posits, fundamentally undermines the relationship between users and technology, transforming individuals from empowered users into passive data sources.

Furthermore, Blin explores the concept of "dark patterns," design elements specifically engineered to manipulate users into taking actions they might not otherwise choose, such as subscribing to unwanted services or sharing more data than intended. He argues that these deceptive practices are widespread and represent a deliberate attempt to exploit users' cognitive biases for profit.

The essay concludes with a somber reflection on the potential consequences of this trend, suggesting that the continued proliferation of anti-personnel computing could lead to a future where individual autonomy is severely curtailed and the very notion of privacy becomes obsolete. Blin urges readers to critically examine their relationship with technology and to actively resist the encroachment of these manipulative systems, advocating for greater awareness and a renewed focus on user empowerment in the design and development of future computing technologies.

Using ChatGPT is not bad for the environment

permalink

Posted: 2025-01-18 04:31:04

The post argues that individual use of ChatGPT and similar AI models has a negligible environmental impact compared to other everyday activities like driving or streaming video. While large language models require significant resources to train, the energy consumed during individual inference (i.e., asking it questions) is minimal. The author uses analogies to illustrate this point, comparing the training process to building a road and individual use to driving on it. Therefore, focusing on individual usage as a source of environmental concern is misplaced and distracts from larger, more impactful areas like the initial model training or even more general sources of energy consumption. The author encourages engagement with AI and emphasizes the potential benefits of its widespread adoption.

In a Substack post entitled "Using ChatGPT is not bad for the environment," author Andy Masley meticulously deconstructs the prevailing narrative that individual usage of large language models (LLMs) like ChatGPT contributes significantly to environmental degradation. Masley begins by acknowledging the genuinely substantial energy consumption associated with training these complex AI models. However, he argues that focusing solely on training energy overlooks the comparatively minuscule energy expenditure involved in the inference stage, which is the stage during which users interact with and receive output from a pre-trained model. He draws an analogy to the automotive industry, comparing the energy-intensive manufacturing process of a car to the relatively negligible energy used during each individual car trip.

Masley proceeds to delve into the specifics of energy consumption, referencing research that suggests the training energy footprint of a model like GPT-3 is indeed considerable. Yet, he emphasizes the crucial distinction between training, which is a one-time event, and inference, which occurs numerous times throughout the model's lifespan. He meticulously illustrates this disparity by estimating the energy consumption of a single ChatGPT query and juxtaposing it with the overall training energy. This comparison reveals the drastically smaller energy footprint of individual usage.

Furthermore, Masley addresses the broader context of data center energy consumption. He acknowledges the environmental impact of these facilities but contends that attributing a substantial portion of this impact to individual LLM usage is a mischaracterization. He argues that data centers are utilized for a vast array of services beyond AI, and thus, singling out individual ChatGPT usage as a primary culprit is an oversimplification.

The author also delves into the potential benefits of AI in mitigating climate change, suggesting that the technology could be instrumental in developing solutions for environmental challenges. He posits that focusing solely on the energy consumption of AI usage distracts from the potentially transformative positive impact it could have on sustainability efforts.

Finally, Masley concludes by reiterating his central thesis: While the training of large language models undoubtedly requires substantial energy, the environmental impact of individual usage, such as interacting with ChatGPT, is negligible in comparison. He encourages readers to consider the broader context of data center energy consumption and the potential for AI to contribute to a more sustainable future, urging a shift away from what he perceives as an unwarranted focus on individual usage as a significant environmental concern. He implicitly suggests that efforts towards environmental responsibility in the AI domain should be directed towards optimizing training processes and advocating for sustainable data center practices, rather than discouraging individual interaction with these powerful tools.
