Bill Gates warned unchecked AI could cause a billion deaths. He called for US lawmakers and enforcers to set safeguards. He said self-regulation is not enough. He described AI in the wrong hands as powerful enough to drive such events. He dismissed a kill switch as inadequate. He noted AI tools are not yet autonomous enough to resist shutdown. He said regulation would add overhead but not slow progress. He also said he does not use AI for personal relationships. He remains chair of the Gates Foundation. He regretted every minute spent with Jeffrey Epstein.
