2026/02/10

Get ready for a rematch with the one & only Bentham’s Bulldog, a.k.a. Matthew Adelstein! Our first debate covered a wide range of philosophical topics.Today’s Debate #2 is all about Matthew’s new argument against the inevitability of AI doom. He comes out swinging with a calculated P(Doom) of just 2.6% , based on a multi-step probability chain that I challenge as potentially falling into a “Type 2 Conjunction Fallacy” (a.k.a. Multiple Stage Fallacy).We clash on whether to expect “alignment by

2025/12/30

In September of 2023, when OpenAI’s GPT-4 was still a fresh innovation and people were just beginning to wrap their heads around large language models, I was invited to debate Beff Jezos, Bayeslord, and other prominent “effective accelerationists” a.k.a. “e/acc” folks on an X Space.E/acc’s think building artificial superintelligence is unlikely to disempower humanity and doom the future, because that’d be an illegal exception to the rule that accelerating new technology is always the

Devin Elliot is a former pro snowboarder turned software engineer who has logged thousands of hours building AI systems. His P(Doom) is a flat ⚫. He argues that worrying about an AI takeover is as irrational as fearing your car will sprout wings and fly away.We spar over the hard limits of current models: Devin insists LLMs are hitting a wall, relying entirely on external software “wrappers” to feign intelligence. I push back, arguing that raw models are already demonstrating native reasoning and

Dr. Michael Timothy Bennett, Ph.D, is an award-winning young researcher who has developed a new formal framework for understanding intelligence. He has a TINY P(Doom) because he claims superintelligence will be resource-constrained and tend toward cooperation.In this lively debate, I stress-test Michael’s framework and debate whether its theorized constraints will actually hold back superintelligent AI.Timestamps* 00:00 Trailer* 01:41 Introducing Michael Timothy Bennett* 04:33 What’s Your P(Doom)?™*

Also, he won the 2013 Nobel Prize in computational biology.I’m thrilled that Prof. Levitt understands the value of raising awareness about imminent extinction risk from superintelligent AI, and the value of debate as a tool to uncover the truth — the dual missions of Doom

Max Harms and Jeremy Gillen are current and former MIRI researchers who both see superintelligent AI as an imminent extinction threat.But they disagree on whether it’s worthwhile to try to aim for obedient, “corrigible” AI as a singular target for current alignment efforts.Max thinks corrigibility is the most plausible path to build ASI without losing control and dying, while Jeremy is skeptical that this research path will yield better superintelligent AI behavior on a sufficiently early try.By

Today I’m sharing my AI doom interview on Donal O’Doherty’s podcast.I lay out the case for having a 50% p(doom). Then Donal plays devil’s advocate and tees up every major objection the accelerationists throw at doomers. See if the anti-doom arguments hold up, or if the AI boosters are just serving sophisticated cope.Timestamps0:00 — Introduction & Liron’s Background 1:29 — Liron’s Worldview: 50% Chance of AI Annihilation 4:03 — Rationalists, Effective Altruists, & AI Developers 5:49 — Major Sources

2025/10/31

Tsvi Benson-Tilsen spent seven years tackling the alignment problem at the Machine Intelligence Research Institute (MIRI). Now he delivers a sobering verdict: humanity has made “basically 0%” progress towards solving it. Tsvi unpacks foundational MIRI research insights like timeless decision theory and corrigibility, which expose just how little humanity actually knows about controlling superintelligence. These theoretical alignment concepts help us peer into the future, revealing the non-obvious,

Former Machine Intelligence Research Institute (MIRI) researcher Tsvi Benson-Tilsen is championing an audacious path to prevent AI doom: engineering smarter humans to tackle AI alignment.I consider this one of the few genuinely viable alignment solutions, and Tsvi is at the forefront of the effort. After seven years at MIRI, he co-founded the Berkeley Genomics Project to advance the human germline engineering approach.In this episode, Tsvi lays out how to lower P(doom), arguing we must stop AGI
