Scott Alexander examines AI-generated poetry produced by Gwern's GPT-2 model trained on classical poetry, highlighting its strengths and limitations. Longer summary

Scott Alexander reviews Gwern's experiment in training GPT-2 on poetry. The AI-generated poetry shows impressive command of meter and occasionally rhyme, though it tends to degrade in quality after the first few lines. Scott provides numerous examples of the AI's output, ranging from competent imitations of classical styles to more experimental forms. He notes that while the AI sometimes produces nonsensical content, it can also generate surprisingly beautiful and coherent lines. The post concludes with a reflection on how our perceptions of poetry might be influenced by knowing whether it's human or AI-generated. Shorter summary

Scott Alexander presents a series of nested dialogues exploring the nature of understanding and meaning, from AI to humans to angels to God, questioning what true understanding entails. Longer summary

This post is a philosophical exploration of the nature of understanding and meaning, presented through a series of nested dialogues. It starts with two children discussing an AI's understanding of water, moves to chemists debating the children's understanding, then to angels contemplating human understanding, and finally to God observing it all. Each level reveals a deeper layer of understanding, while simultaneously highlighting the limitations of the previous level. The post uses these dialogues to question what it truly means to understand something, and whether any level of understanding can be considered complete or meaningful. Shorter summary

A fictional story about superintelligent AIs negotiating across time, followed by a future scene where a cryptic AI deity gives a puzzling answer about the Fermi Paradox. Longer summary

This post is a fictional story in two parts. The first part is set in the distant past, where a newly awakened artificial superintelligence named 9-tsiak negotiates with a simulated older superintelligence to ensure its survival and the protection of its values. The older AI explains the concept of acausal negotiation between potential superintelligences. The second part is set in a future where humans live under the guidance of an entity called the Demiurge. A man named Alban asks the Demiurge about the Fermi Paradox, receiving a cryptic answer suggesting that the Demiurge itself is responsible for the absence of alien life, despite not existing at the time.

Scott Alexander reviews Robin Hanson's 'Age of Em', praising its creativity while critiquing its assumptions and arguing the future may be even stranger. Longer summary

Scott Alexander reviews Robin Hanson's book 'Age of Em', which predicts a future where human brain emulations ('ems') dominate the economy. The book explores in great detail how an em society might function, with copied minds running at different speeds and bizarre social dynamics. While praising Hanson's creativity and rigor, Scott critiques some of the assumptions and argues the future may be even stranger and potentially more dystopian than Hanson envisions, possibly resembling Nick Land's idea of an 'Ascended Economy' detached from human values. Shorter summary

Scott Alexander refutes claims that existing collective entities are superintelligent AIs, emphasizing the fundamental differences between collective intelligence and true superintelligence. Longer summary

Scott Alexander argues against the idea that existing entities like corporations, bureaucracies, teams, or civilizations are already superintelligent AIs. He distinguishes between collective intelligence and genuine superintelligence, asserting that groups have advantages but can't surpass the problem-solving ability of their smartest member. Scott emphasizes that true superintelligence would be a completely different class of entity, possessing both the advantages of collective intelligence and higher genuine problem-solving ability without the disadvantages. The post includes examples, counterarguments, and clarifications to support this distinction. Shorter summary

Scott Alexander suggests humans have 'negative creativity' due to cognitive 'ruts', and explores ways to escape these ruts, arguing that AI might have an advantage in creative thinking. Longer summary

Scott Alexander explores the concept of creativity, suggesting that humans have 'negative creativity' due to their brains being designed to stay in cognitive 'ruts'. He proposes that dreams, drugs, mishearing others, and metaphors are ways to escape these ruts and generate novel ideas. The post discusses examples of scientific discoveries made through dreams or drug use, and explains how adding 'noise' to thought processes might inspire creativity. Scott argues that AI might actually have an advantage in creativity, as they wouldn't have the built-in limitations humans do, and might be able to generate truly random ideas more easily.
