California Governor Gavin Newsom has vetoed SB 1047, a sweeping artificial intelligence safety bill, arguing that it is not the best way to deal with the looming threats and opportunities presented by AI.

California Gov. Gavin Newsom on Sunday vetoed a landmark artificial intelligence bill that was designed to have first-in-the-nation safety regulations against AI misuse. The big picture: The backers of the bill that would've required AI developers to comply with certain rules before developing models had argued it would provide AI safety with workable provisions at a time when Congress has stalled on the matter and the EU has taken a lead

SAG-AFTRA backed the bill, SB 1047, the first time it has taken a stand on broader AI issues unrelated to entertainment.
