The Most Likely AI Doom Scenario — with Jim Babcock, LessWrong Team 30.04.2025

What’s the most likely (“mainline”) AI doom scenario? How does the existence of LLMs update the original Yudkowskian version? I invited my friend Jim Babcock to help me answer these questions. Jim is a member of the LessWrong engineering team and its parent organization, Lightcone Infrastructure. I’ve been a longtime fan of his thoughtful takes. This turned out to be a VERY insightful and informat...

Gödel's Theorem Says Intelligence ≠ Power? AI Doom Debate with Alexander Campbell 21.03.2025

Alexander Campbell claims that having superhuman intelligence doesn’t necessarily translate into having vast power, and that Gödel's Incompleteness Theorem ensures AI can’t get too powerful. I strongly disagree.

Alignment is EASY and Roko's Basilisk is GOOD?! 17.03.2025

Roko Mijic has been an active member of the LessWrong and AI safety community since 2008. He’s best known for “Roko’s Basilisk”, a thought experiment he posted on LessWrong that made Eliezer Yudkowsky freak out, and years later became the topic that helped Elon Musk get interested in Grimes.

We Found AI's Preferences — What David Shapiro MISSED in this bombshell Center for AI Safety paper 21.02.2025

The Center for AI Safety just dropped a fascinating paper — they discovered that today’s AIs like GPT-4 and Claude have preferences! As in, coherent utility functions. We knew this was inevitable, but we didn’t know it was already happening. This episode has two parts: In Part I (48 minutes), I react to David Shapiro’s coverage of the paper and push back on many of his points. In Part II (60 minut...

Does AI Competition = AI Alignment? Debate with Gil Mark 10.02.2025

My friend Gil Mark, who leads generative AI products at LinkedIn, thinks competition among superintelligent AIs will lead to a good outcome for humanity. In his view, the alignment problem becomes significantly easier if we build multiple AIs at the same time and let them compete. I completely disagree, but I hope you’ll find this to be a thought-provoking episode that sheds light on why the align...

Toy Model of the AI Control Problem 06.02.2025

Why does the simplest AI imaginable, when you ask it to help you push a box around a grid, suddenly want you to die? AI doomers are often misconstrued as having "no evidence" or just "anthropomorphizing". This toy model will help you understand why a drive to eliminate humans is NOT a handwavy anthropomorphic speculation, but rather something we expect by default from any sufficiently powerful sea...
