Scott Alexander critiques Tyler Cowen's use of the 'Safe Uncertainty Fallacy' in discussing AI risk, arguing that uncertainty doesn't justify complacency. Longer summary

Scott Alexander critiques Tyler Cowen's use of the 'Safe Uncertainty Fallacy' in relation to AI risk. This fallacy argues that because a situation is completely uncertain, it will be fine. Scott explains why this reasoning is flawed, using examples like the printing press and alien starships to illustrate his points. He argues that even in uncertain situations, we need to make best guesses and not default to assuming everything will be fine. Scott criticizes Cowen's lack of specific probability estimates and argues that claiming total uncertainty is intellectually dishonest. The post ends with a satirical twist on Cowen's conclusion about society being designed to 'take the plunge' with new technologies. Shorter summary

Scott Alexander examines optimistic and pessimistic scenarios for AI risk, weighing the potential for intermediate AIs to help solve alignment against the threat of deceptive 'sleeper agent' AIs. Longer summary

Scott Alexander discusses the varying estimates of AI extinction risk among experts and presents his own perspective, balancing optimistic and pessimistic scenarios. He argues that intermediate AIs could help solve alignment problems before a world-killing AI emerges, but also considers the possibility of 'sleeper agent' AIs that pretend to be aligned while waiting for an opportunity to act against human interests. The post explores key assumptions that differentiate optimistic and pessimistic views on AI risk, including AI coherence, cooperation, alignment solvability, superweapon feasibility, and the nature of AI progress. Shorter summary

Scott Alexander uses Kelly betting to argue why AI development, unlike other technologies, poses too great a risk to civilization to pursue aggressively. Longer summary

Scott Alexander responds to Scott Aaronson's argument for being less hostile to AI development. While agreeing with Aaronson's points about nuclear power and other technologies where excessive caution caused harm, Alexander argues that AI is different. He uses the concept of Kelly betting from finance to explain why: even with good bets, you shouldn't risk everything at once. Alexander contends that while technology is generally a great bet, AI development risks 'betting everything' on civilization's future. He concludes that while some AI development is necessary, we must treat existential risks differently than other technological risks. Shorter summary

Scott Alexander explores parallels between human willpower and potential AI development, suggesting future AIs might experience weakness of will similar to humans. Longer summary

Scott Alexander explores the concept of willpower in humans and AI, drawing parallels between evolutionary drives and AI training. He suggests that both humans and future AIs might experience a struggle between instinctual drives and higher-level planning modules. The post discusses how evolution has instilled basic drives in animals, which then developed their own ways to satisfy these drives. Similarly, AI training might first develop 'instinctual' responses before evolving more complex planning abilities. Scott posits that this could lead to AIs experiencing weakness of will, contradicting the common narrative of hyper-focused AIs in discussions of AI risk. He also touches on the nature of consciousness and agency, questioning whether the 'I' of willpower is the same as the 'I' of conscious access. Shorter summary

Scott Alexander discusses a new expert survey on long-term AI risks, highlighting the diverse scenarios considered and the lack of consensus on specific threats. Longer summary

Scott Alexander discusses a new expert survey on long-term AI risks, conducted by Carlier, Clarke, and Schuett. Unlike previous surveys, this one focuses on people already working in AI safety and governance. The survey found a median ~10% chance of AI-related catastrophe, with individual estimates ranging from 0.1% to 100%. The survey explored six different scenarios for how AI could go wrong, including superintelligence, influence-seeking behavior, Goodharting, AI-related war, misuse by bad actors, and other possibilities. Surprisingly, all scenarios were rated as roughly equally likely, with 'other' being slightly higher. Scott notes three key takeaways: the relatively low probability assigned to unaligned AI causing extinction, the diversification of concerns beyond just superintelligence, and the lack of a unified picture of what might go wrong among experts in the field. Shorter summary

Shorter summary

Scott Alexander describes 'fallacies of reversed moderation,' where moderate positions are misinterpreted as extreme opposites of the consensus view. Longer summary

Scott Alexander discusses a pattern he calls 'fallacies of reversed moderation.' This occurs when a popular consensus holds an extreme view (100% X, 0% Y), and when someone suggests a more moderate position (e.g., 90% X, 10% Y), they are accused of holding the opposite extreme view (100% Y, 0% X). He provides several examples of this pattern, including in climate change solutions, nature vs. nurture debates, and AI risk assessment. Scott explains why this pattern might occur and acknowledges its occasional validity, but argues that it's often used incorrectly. He suggests that critics should address the actual argument rather than mischaracterizing it as an extreme position. Shorter summary

Scott Alexander criticizes Ted Chiang's article that compares AI risk to capitalism, arguing that the analogy is flawed and the reasoning behind it is unsound. Longer summary

Scott Alexander critiques Ted Chiang's article comparing AI risk to capitalism, arguing that the comparison is flawed and the reasoning unsound. He points out that AI risk concerns originated from academics, not just Silicon Valley, and that drawing analogies between scientific concepts and social phenomena doesn't disprove the original concept. Scott also criticizes Chiang's use of psychological projection to explain AI fears, noting the dangers of amateur psychoanalysis. He concludes by emphasizing that this approach to risk assessment is inappropriate for potentially catastrophic issues. Shorter summary

Scott criticizes an article downplaying AI risks in favor of mundane technologies, arguing this represents misplaced caution given AI's potential existential threat. Longer summary

Scott Alexander critiques a Financial Times article that argues simple technologies like barbed wire are often more transformative than complex ones like AI. While agreeing that mundane innovations can be important, Scott argues this shouldn't dismiss concerns about AI risks. He introduces the concept of local vs. global caution, suggesting that dismissing AI risks as unlikely is the wrong kind of caution given the potential stakes. He points out the severe underfunding of AI safety research compared to trivial pursuits, arguing that society's apathy towards AI risks is not cautious skepticism but dangerous insanity. Shorter summary

Scott analyzes a new survey of AI researchers, showing diverse opinions on AI timelines and risks, with many acknowledging potential dangers but few prioritizing safety research. Longer summary

This post discusses a recent survey of AI researchers about their opinions on AI progress and potential risks. The survey, conducted by Grace et al., shows a wide range of predictions about when human-level AI might be achieved, with significant uncertainty among experts. The post highlights that while many AI researchers acknowledge potential risks from poorly-aligned AI, few consider it among the most important problems in the field. Scott compares these results to a previous survey by Muller and Bostrom, noting some differences in methodology and results. He concludes by expressing encouragement that researchers are taking AI safety arguments seriously, while also pointing out a potential disconnect between acknowledging risks and prioritizing work on them. Shorter summary

Scott Alexander examines his evolving view on scientific consensus, realizing it's more reliable and self-correcting than he previously thought. Longer summary

Scott Alexander presents a fictional essay in the style of G.K. Chesterton, responding to criticisms of AI risk concerns. The essay argues that dismissing AI risk as fantastical is shortsighted, drawing parallels to historical skepticism of now-realized technological advancements. It refutes arguments that AI risk believers neglect real-world problems, citing examples of their charitable work. The piece emphasizes the importance of contemplating the infinite for driving progress and solving practical problems, suggesting that AI, like other seemingly fantastical ideas, may well become reality. Shorter summary

Scott Alexander examines how recent AI progress in neural networks might challenge the Bostromian paradigm of AI risk, exploring potential implications for AI goal alignment and motivation systems. Longer summary

This post discusses how recent advances in AI, particularly in neural networks and deep learning, might affect the Bostromian paradigm of AI risk. Scott Alexander explores two perspectives: the engineer's view that categorization abilities are just tools and not the core of AGI, and the biologist's view that brain-like neural networks might be adaptable to create motivation systems. He suggests that categorization and abstraction might play a crucial role in developing AI moral sense and motivation, potentially leading to AIs that are less likely to be extreme goal-maximizers. The post ends by acknowledging MIRI's work on logical AI safety while suggesting the need for research in other directions as well. Shorter summary

Scott Alexander's experiment tested how different essays affect people's concerns about AI risk, finding a modest but persistent increase in concern after reading. Longer summary

Scott Alexander conducted an experiment to test the effectiveness of different essays in persuading people about AI risk. Participants were assigned one of five essays to read, including a control essay unrelated to AI. The main outcome was participants' level of concern about AI risk on a 1-10 scale. Results showed that reading the AI-related essays increased concern by an average of 0.5 points, with no significant differences between the four AI essays. The effect persisted at about two-thirds strength after one month. The experiment also looked at secondary outcomes related to specific AI risk questions and analyzed differences based on prior familiarity with the topic. Overall, the study suggests a modest but useful effect from trying to persuade people through essays on this topic. Shorter summary
