Host Ben Bradford explores the existential risk of artificial intelligence, interviewing AI expert Katja Grace and national security analyst Hamza Chaudhry. They outline a "doom scenario" requiring superintelligent, autonomous agents with misaligned goals and access to destructive weapons. The episode examines why major institutions view AI as a top global threat alongside nuclear war and climate change. Finally, it discusses potential safeguards, including mandatory safety testing, whistleblower protections, and emergency off-switches to prevent catastrophe.
