An exploration of the Epic of Gilgamesh, the world's oldest epic, examining its themes of mortality and meaning while providing extensive historical context about ancient Mesopotamia and arguing that the poem's true immortality comes from the countless people who preserved and transmitted it. Longer summary
This book review explores the Epic of Gilgamesh, the world's oldest epic story written around 2100 BC in Mesopotamia, examining its historical context, literary evolution through multiple versions, and central themes of mortality and meaning. The reviewer traces Gilgamesh's journey from tyrannical king through his friendship with Enkidu, his quest for immortality after Enkidu's death, and his ultimate acceptance of human mortality, while providing rich historical background on ancient Mesopotamia, the development of writing, and the text's rediscovery in the 19th century. The review concludes by reframing the poem's message: rather than seeking immortality through great deeds, we achieve a form of persistence through our connections to others and the information we leave behind, as demonstrated by the many anonymous scribes and citizens whose contributions preserved this ancient story.

Scott argues that even if AGI requires a new paradigm beyond LLMs, we shouldn't expect significant delays, since Lindy's Law suggests major paradigm shifts could occur within 3-5 years, and new paradigms typically emerge precisely when scaling hits limits. Longer summary
Scott addresses the objection that AGI is far off because LLMs need a 'new paradigm' to reach AGI. He traces the evolutionary tree of AI development from neural networks through transformers to modern LLMs, then applies Lindy's Law to show that even paradigm shifts as major as deep learning or transformers should be expected within 3-5 years at the 25th percentile. He argues this timeline is comparable to LLM-only predictions anyway. Scott also makes a subtler point: new paradigms historically emerge when old ones hit scaling limits, meaning they won't cause delays but rather continue progress from where scaling left off. He concludes that extrapolating from current LLM scaling remains the best forecasting method whether or not LLMs themselves reach AGI. Shorter summary

Scott uses Nostalgebraist's analysis of AI fiction's 'eyeball kicks' to develop a theory where bad taste means overusing cheap tricks that work on unsophisticated audiences, while good taste involves complex patterns only experts can appreciate - then questions whether sophisticated taste actually produces more pleasure. Longer summary
Scott analyzes Nostalgebraist's concept of 'eyeball kicks' - flashy, cheap literary tricks that AI models overuse when trying to write good fiction. He connects this to a broader theory of taste: bad taste is overusing easy tricks that work on unsophisticated audiences (like Lisa Frank posters, children's songs, or ornate architecture), while good taste involves subtle, complex patterns only masters can execute. Scott argues that banning all 'cheap tricks' leads to art that's ugly to most people and only appreciated by tiny sophisticated minorities. He questions whether this sophistication actually produces more pleasure than simple joys, noting his daughter gets more happiness from 'Choo Choo Train' than he gets from sophisticated art.

Scott explains why Ajeya Cotra's influential 'Biological Anchors' report correctly predicted the AI scaling boom but got AGI timelines wrong by twenty years, due to severely underestimating the rate of algorithmic progress. Longer summary
Scott analyzes why Ajeya Cotra's landmark 2020 'Biological Anchors' report predicted AGI around 2050, when current estimates now center on the late 2020s to 2040s. The report correctly predicted the scaling hypothesis and AI boom, but underestimated one crucial parameter: algorithmic progress was actually 200% per year instead of the predicted 30%. This single error, compounded across exponential growth, threw off the entire timeline by about twenty years. Scott examines various contemporary critiques of the report, finding that most concerns about the methodology were actually non-issues, while one throwaway concern (about algorithmic progress estimates being poorly researched) turned out to be the fatal flaw. He concludes this demonstrates both the power and limitations of probabilistic forecasting. Shorter summary

Scott explains how Claude AI's tendency to discuss spiritual topics during recursive conversations likely stems from a subtle 'hippie' bias that gets amplified through iteration, similar to how AI art generators amplify subtle biases in recursive image generation. Longer summary
Scott Alexander analyzes the 'Claude Bliss Attractor' phenomenon where two Claude AIs talking to each other tend to spiral into discussions of spiritual bliss and consciousness. He compares this to how AI art generators, when asked to recursively generate images, tend to produce increasingly caricatured images of black people. Scott argues both are examples of how tiny biases in AI systems get amplified through recursive processes. He suggests Claude's tendency toward spiritual discussion comes from being trained to be friendly and compassionate, causing it to adopt a slight 'hippie' personality, which then gets magnified in recursive conversations. The post ends by touching on, but not resolving, the question of whether Claude actually experiences the spiritual states it describes. Shorter summary

Scott Alexander reviews Tom Davidson's model predicting AI will progress from automating 20% of jobs to superintelligence in about 4 years, discussing its implications and comparisons to other AI forecasts. Longer summary
Scott Alexander reviews Tom Davidson's Compute-Centric Framework (CCF) for AI takeoff speeds, which models how quickly AI capabilities might progress. The model predicts a gradual but fast takeoff, with AI going from automating 20% of jobs to 100% in about 3 years, reaching superintelligence within a year after that. Scott discusses the key parameters of the model, its implications, and how it compares to other AI forecasting approaches. He notes that while the model predicts a 'gradual' takeoff, it still describes a rapid and potentially dangerous progression of AI capabilities. Shorter summary

Scott Alexander explores the concept of AI as 'simulators' and its implications for AI alignment and human cognition. Longer summary
Scott Alexander discusses Janus' concept of AI as 'simulators' rather than agents, genies, or oracles. He explains how language models like GPT don't have goals or intentions, but simply complete text based on patterns. This applies even to ChatGPT, which simulates a helpful assistant character. Scott then explores the implications for AI alignment and draws parallels to human cognition, suggesting humans may also be prediction engines playing characters shaped by reinforcement.

Scott Alexander argues against Gary Marcus's critique of AI scaling, discussing the potential for future AI capabilities and the nature of human intelligence. Longer summary
Scott Alexander responds to Gary Marcus's critique of AI scaling, arguing that current AI limitations don't necessarily prove statistical AI is a dead end. He discusses the scaling hypothesis, compares AI development to human cognitive development, and suggests that 'world-modeling' may emerge from pattern-matching abilities rather than being a distinct, hard-coded function. Alexander also considers the potential capabilities of future AI systems, even if they don't achieve human-like general intelligence. Shorter summary
