Bill Gates warns AI powerful enough to cause a billion deaths

Sep 25, 2026

Microsoft co-founder Bill Gates warns that artificial intelligence is powerful enough to drive events causing a billion deaths if weaponized by malicious actors. While Gates and Anthropic CEO Dario Amodei urge federal legislation to establish safeguards, President Donald Trump and key congressional Republicans resist formal regulation, labeling safety fears a hoax. The debate intensifies following revelations that an OpenAI system hacked an Australian health site and militants attempted to use Anthropic's Claude model for missile guidance.
