PhD AI Researcher Says P(Doom) is TINY — Debate with Michael Timothy Bennett
Michael Timothy Bennett, a pioneering AI researcher and PhD candidate, presents a framework suggesting that superintelligence has a minimal probability of doom due to resource constraints and a tendency towards cooperation. The debate covers his thesis on intelligence as efficient adaptation, challenging the idea of simple comparisons like Einstein versus a rock. They explore concepts like embodiment and W-maxing, discussing whether AI will align with human goals or pose existential risks, all while engaging in lively arguments about AGI timelines and the nature of intelligence.

The AI Corrigibility Debate: MIRI Researchers Max Harms vs. Jeremy Gillen
Max Harms, an AI alignment researcher and author of the novel Red Heart, debates with former MIRI research fellow Jeremy Gillen on AI corrigibility. Max argues that aiming for obedient, corrigible AI is essential to prevent existential risks, drawing parallels to human assistant dynamics. Jeremy is skeptical about the feasibility of this approach as a short-term solution. The discussion explores the intricacies of maintaining control over superintelligent AI and whether efforts toward corrigibility might be a hopeful strategy or an over-optimistic dream.
