Doom Debates!

Dr. Mike Israetel is back in the arena to FIGHT ME (verbally) about the likelihood of AI killing everyone vs. the likelihood of AI making the universe totally awesome!
Back by popular demand after last year’s widely-viewed debate, the renowned exercise scientist, fitness entrepreneur, and low-P(Doom) AI futurist reveals where he gets off the Doom Train™, why he thinks AI is conscious, and how he pictures the coming AI utopia.

Claude, also known as @lumpenspace on X, is a prominent AI accelerationist. He gives humanity a 30% chance of being superseded by superintelligence, and he’s fine with it! We unpack his lattice of beliefs, and pinpoint the cruxes of our disagreement on the orthogonality thesis and the capabilities of superintelligence.
Lumpenspace’s appearance comes after a Molotov cocktail was thrown at Sam Altman’s house, an act that he and I completely condemn.

📢 BREAKING: A man known only as "@47fucb4r8c69323" just paid Eliezer Yudkowsky $10,000 to have a raw, uncut, public debate on my YouTube channel!
Tensions run high as 47f confronts Eliezer about his "If anyone builds it, everyone dies" rhetoric, warning it could incite unstable individuals to harm AI researchers and their families, while Eliezer maintains that the possibility of extinction from superintelligent AI is too high to *not* speak out about.They also clash over whether we truly understand how LLMs work. Yudkowsky highlights the lack of extracted algorithms that explain their qualitative intelligence, while 47f dismisses these concerns as a fundamental misunderstanding of how text modeling works.
While this may not be the highest quality debate I’ve ever hosted, I hope it’s a step toward more attention and public discourse on this urgent, high-stakes topic.
P.S. Please consider supporting my work with a tax-deductible donation. Read more…
