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.
