Will AI Kill Everyone by 2050? Debate with Dr. Casey Hart (Ontology Explained)

Casey Hart is a professional ontologist who has closely studied If Anyone Builds It, Everyone Dies and concluded the arguments are bad. His P(Doom) is under 1%, and he wouldn’t bet on AGI arriving before 2075. Casey and I agree AI has become remarkably capable and we need more accountability towards the companies building it. But we disagree on where the future is headed. I believe uncontrollable superintelligence could soon wipe out humanity. He calls that a “pretty outlandish hypothesis.” Casey holds a doctorate in philosophy from the University of Wisconsin–Madison, and has worked as an ontologist at Ford, Amazon, and Cycorp (maker of Cyc). Can this professional philosopher convince me that AI doom is just a story, and not even a well-argued one?
