28 Nations Sign Bletchley Declaration on AI Safety at UK Summit, But Critics Argue it's More Symbolism Than Substance

28 governments, including the U.S. and China, signed the Bletchley Declaration agreeing to cooperate on evaluating A.I. risks at a UK summit.

The declaration warned of potential "catastrophic" harm from advanced A.I. systems, but set no specific policy goals.

Speakers like UK PM Sunak hoped the summit would position the UK as an A.I. leader, given Bletchley Park's WWII codebreaking history.

Attendees like Kamala Harris and tech executives discussed balancing innovation with regulation to ensure A.I. safety.

Critics argued the summit was more symbolic than substantive, with many leaders absent and countries like the EU and China moving ahead with their own regulations.
