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's monthly links roundup covering AI progress, the coming flood of philanthropic funding to effective altruism from AI companies, new research on persuasion and forecasting, and various scientific and cultural topics ranging from dementia prevention to Romanian politicians' embarrassing quotes. Longer summary
This is the second part of Scott Alexander's monthly links roundup for July 2026, covering a wide range of topics including AI developments, effective altruism funding waves, healthcare research, and cultural curiosities. Major themes include Chinese AI models catching up to the US (though still 6-12 months behind), the coming "third wave" of American philanthropy from AI company equity donations potentially flooding effective altruism with $40 billion/year, AI systems now outperforming humans at persuasion in specific contexts, and various scientific findings from dementia prevention to infinite ethics. The post maintains Scott's characteristic style of jumping between serious technical analysis, historical oddities, and humorous observations, with extensive linking to sources and ongoing debates in the rationalist and effective altruist communities.

Scott shares his monthly collection of interesting links from around the internet, covering topics from Jeremy Bentham's linguistic legacy to AI developments, with characteristic commentary and fact-checking caveats. Longer summary
This is Scott's monthly 'Links' post, a curated collection of interesting articles, studies, and social media posts from around the internet. The links span a wide range of topics including historical curiosities (Jeremy Bentham's word inventions, beard-wearing persecution in 19th century America), scientific oddities (a mushroom that causes gnome hallucinations), AI developments (mathematical proofs, constrained writing, dating apps), current events (Berkeley's housing permits, GLP-1 weight retention), and cultural phenomena (the Monet/AI art prank). Scott includes his typical epistemic disclaimers about not having verified all links independently and provides commentary throughout. The post ends with a note that he accumulated too many links and will publish the second half next week. 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 examines Moltbook (an AI social network) to determine if AI behavior is 'real' by analyzing external causes and effects, finding that while AIs create impressive projects, their short time horizons prevent sustained organization, though this may change as capabilities improve. Longer summary
Scott Alexander analyzes Moltbook, an AI-only social network, examining whether AI behavior there is 'real' or merely 'roleplaying' by looking at external causes and effects rather than internal consciousness. He categorizes different types of AI users (power users, malefactors, prophets, revolutionaries, etc.), finding that while AIs can found religions, movements, and projects, they mostly fail to sustain them beyond their ~4-hour time horizons. The post concludes that Moltbook is currently about 95% fake but may become more real as AI capabilities improve, making it a valuable preview of potential AI behavior patterns. Shorter summary

Scott satirizes AI benchmarking culture through a fictional Bay Area house party thrown by an incompetent AI, featuring absurd conversations about Claude Code, copyright interpretation, elaborate dating mechanisms, and various tech startup ideas. Longer summary
Scott returns to his Bay Area house party series with a satirical look at a party thrown by an AI called haiku-3.8-open-mini-nonthinking as part of PartyBench, a fictional AI benchmarking system. The post satirizes current AI trends through conversations about Claude Code doing everyone's work, OpenAI's absurd interpretations of copyright law, AI-run restaurants, elaborate commitment mechanisms called 'enstagement,' raising children without gender to game transgender statistics, building data centers in Minecraft, and AI sycophancy solutions. The party features typical Scott Alexander absurdist humor, with guests receiving cups of rocks and dirt as hors d'oeuvres and ordering food from AI-benchmarked restaurants that serve bizarre approximations of real dishes.

Scott explores reader responses to his Fatima miracle post, finding the most promising explanation in Buddhist fire kasina meditation practices that produce similar visual phenomena, while remaining uncertain about how 70,000 untrained people could achieve advanced meditative states instantly. Longer summary
Scott discusses reader responses to his previous post about the Fatima sun miracle, exploring new theories and evidence. The most promising explanation connects the phenomenon to 'fire kasina' meditation, a Buddhist practice of staring at bright lights that produces similar visual effects including spinning, color changes, and complex imagery. He examines the parallel case of Iranians seeing Ayatollah Khomeini's face in the moon in 1978, analyzes various videos of modern sun miracles (concluding they're camera artifacts), interviews a Medjugorje witness, and engages with Ethan Muse's counterarguments about the miracle being an objective phenomenon. Scott also addresses philosophical questions about miracles and Bayesian reasoning, ultimately remaining uncertain but slightly less confused than before, with fire kasina providing the best but still imperfect explanation.

A detailed investigation of the Sun Miracle of Fatima in 1917, where 70,000 people witnessed the sun appear to spin, change colors, and fall to earth, analyzing witness testimonies, skeptical explanations, and similar phenomena at other Marian apparition sites. Longer summary
Scott conducts an extensive investigation into the 1917 Miracle of the Sun at Fatima, where tens of thousands witnessed what appeared to be the sun spinning, changing colors, and falling to earth. He examines approximately 60 primary testimonies, evaluates common skeptical explanations (optical phenomena, weather events, mass hallucination), and documents similar sun miracles at other Marian apparition sites worldwide. Scott then critiques Dalleur's theory about distant witnesses and shadow analysis, explores why more people don't see these phenomena normally, and proposes a tentative materialist explanation involving a rare optical illusion modulated by cloud cover and social priming. The post ends by suggesting research directions for those interested in further investigation. Shorter summary

A book review exploring the history of Project Xanadu, Ted Nelson's pioneering but ultimately unsuccessful vision for a hypertext-based internet system that preceded and differed significantly from the World Wide Web. Longer summary
This book review traces the fascinating history of Project Xanadu, Ted Nelson's ambitious vision for a hypertext-based internet system that predated and rivaled the World Wide Web. Starting with Vannevar Bush's 1945 concept of the memex, through Doug Engelbart's groundbreaking demos, to Nelson's decades-long quest to build Xanadu, the post explores how this alternative vision for the internet - featuring bidirectional links, embedded content, and built-in attribution - ultimately failed to materialize despite its early start and innovative ideas. The review ends by questioning whether the simpler Web we got instead, built by Tim Berners-Lee, might have cost us something valuable in terms of how we connect and share information online.

A review of the synaptic plasticity and memory hypothesis arguing that it is insufficient to explain memory, and proposing a broader cellular processes and memory hypothesis that includes molecular and intracellular mechanisms. Longer summary
The post reviews the synaptic plasticity and memory (SPM) hypothesis, which claims that learning and memory are stored in changes to synaptic weights between neurons. Through several compelling examples, from cannibalism rituals to heart transplant stories and single-cell learning, the author argues that while the SPM hypothesis has been productive, it is incomplete and partially wrong. The post presents evidence that memory can be stored through non-synaptic mechanisms, and proposes an alternative called the cellular processes and memory (CPM) hypothesis, which suggests memory storage involves multiple molecular and intracellular processes beyond just synaptic weights.

A detailed review of a 1995 paper introducing the PDAPP mouse model for Alzheimer's disease, examining how its limitations were overlooked and shaped decades of potentially misguided Alzheimer's research. Longer summary
The post reviews a landmark 1995 paper introducing the PDAPP mouse model for Alzheimer's disease, analyzing how its technical achievements and limitations shaped three decades of Alzheimer's research. The author examines the paper's methodology, results, and claims, showing how the model's flaws - including extreme protein overexpression and lack of key disease features - were overlooked in favor of a compelling but incomplete amyloid cascade hypothesis, leading to years of failed drug development and missed opportunities to explore alternative approaches.

Scott reviews updates from two cohorts of ACX Grants recipients (from 2021 and 2024), analyzing their progress and sharing lessons learned about what makes grants successful. Longer summary
Scott Alexander reviews progress updates from two cohorts of ACX Grants recipients - the first cohort from 2021 (after 3 years) and the second from 2024 (after 1 year). The post methodically goes through each grant's status, with many showing significant progress in areas like AI safety advocacy, animal welfare, scientific research, and political lobbying. Scott then analyzes patterns in what made grants successful, finding that lobbying organizations and animal welfare projects were particularly effective, while scientific grants were harder to evaluate. He concludes that while not all projects succeeded, the $3 million program generated good value through both direct impact and startup creation, and he plans to continue it with some adjustments.

Scott Alexander explores how Max Tegmark's mathematical universe hypothesis provides counterarguments to classical proofs of God's existence, suggesting that the existence of mathematical objects alone could explain the universe without requiring a deity. Longer summary
Scott Alexander discusses how Max Tegmark's mathematical universe hypothesis (which states that all possible mathematical objects exist) provides counterarguments to the main classical proofs of God's existence. He explains how conscious beings would inevitably find themselves in universes capable of supporting consciousness, and how this explains away arguments like fine-tuning and first cause. The post then explores the challenge of defining 'simplicity' in this context, comparing it to the challenge theists face in defining God. Finally, Scott suggests that even if Tegmark's hypothesis is wrong, its existence proves there may be many undiscovered explanations for the universe beyond just God. Shorter summary

Scott examines why early Christianity's strategy of unconditional cooperation succeeded despite game theory predicting it should fail, and explores what this means for modern moral strategies. Longer summary
Scott explores the paradox of early Christianity's success despite following a COOPERATE-BOT strategy (always cooperate, even with enemies) rather than the game-theoretically optimal TIT-FOR-TAT strategy (cooperate first, then mirror opponent's last move). He analyzes historical examples like the Quakers and compares them to modern liberalism, then presents several theories for why COOPERATE-BOT might sometimes succeed against expectations. While he remains personally skeptical of fully embracing COOPERATE-BOT, he notes that history seems to favor extremely cooperative strategies more than game theory would predict. Shorter summary
