Description: Casey Hart is a professional ontologist who has closely studied If Anyone Builds It, Everyone Dies and concluded the arguments are bad. His P(Doom) is under 1%, and he wouldn’t bet on AGI arriving before 2075.Casey and I agree AI has become remarkably capable and we need more accountability towards the companies building it. But we disagree on where the future is headed. I believe uncontrollable superintelligence could soon wipe out humanity. He calls that a “pretty outlandish hypothesis.”Casey holds a doctorate in philosophy from the University of Wisconsin–Madison, and has worked as an ontologist at Ford, Amazon, and Cycorp (maker of Cyc).Can this professional philosopher convince me that AI doom is just a story, and not even a well-argued one?Watch on YouTube: https://www.youtube.com/watch?v=oxHKesSpqBMTimestamps00:00:00 — Cold Open00:01:04 — Introducing Casey Hart00:03:08 — What Is Ontology?00:08:49 — Inside Cyc, the Original Common-Sense AI00:19:14 — Do LLMs Actually Understand Anything?00:25:36 — What’s Your P(Doom)?™00:29:42 — Casey’s Case for Under 1%00:34:24 — Does Casey’s Christianity Factor In?00:40:50 — Timelines and Scaling Laws00:49:44 — Could an AI CEO Beat a Human CEO by 2050?00:52:21 — AGI Over/Under: 207500:55:29 — Rogue AI as a Computer Virus01:14:52 — Putting Numbers on Each Step of the Doom Argument01:26:40 — Planes vs. Birds: What Mature Intelligence Looks Like01:31:05 — The “Outcome Slot”01:42:32 — Would a Superintelligence Just Compose Music in a Cabin?01:47:22 — One Prompt Away from a Dyson Swarm01:52:39 — Was Navier–Stokes an AI Alley-Oop?02:00:43 — S-Curves vs. Exponentials02:08:14 — Casey’s Critique of If Anyone Builds It, Everyone Dies02:14:15 — Is the Doom Train Biased?02:23:24 — AI Policy: Liability vs. Pausing AI02:29:50 — The Crux, and Liron Steelmans Casey02:33:29 — Wrap-UpLinksCASEY HARTOntology Explained — Casey’s YouTube channelThe first video in Casey's series on IABIED, “The Case for Superintelligence Is Surprisingly Thin” — Casey on Chapter 1Philosophy, Programs, and Prompts — Casey’s podcast with Carl Brown (Spotify)“Artificial General Intelligence?: Wanna Bet?” — Ep 1, where Casey sets his AGI over/under at 2075REFERENCED IN THE EPISODEIf Anyone Builds It, Everyone Dies — Eliezer Yudkowsky & Nate SoaresCyc — Doug Lenat’s hand-built common-sense knowledge baseThe Hanson-Yudkowsky AI-Foom Debate (2008) — where Hanson backed Cyc and Eliezer didn’tLean — the formal proof languageOn the Navier–Stokes Millennium Prize Problem — OpenAIThe Hugging Face incident and the road ahead — OpenAIMorris worm (1988)“On the Loose” — Dean W.
