Co-founder and CEO of Anthropic. His correspondence with the U.S. Department of War over AI-use guardrails — barring fully autonomous weapons and domestic surveillance — surfaced as exhibits in Anthropic PBC v. U.S. Department of War, a rare public record of a frontier-AI CEO negotiating red lines with the government.
