California's SB 1047, a contentious artificial intelligence safety bill, has passed the state Assembly with a 41-9 vote and is set for a final confirmation vote in the Senate before reaching Governor Gavin Newsom. The bill mandates that AI developers take precautions to prevent severe harm, including implementing a kill switch, third-party testing, and offering whistleblower protections. While proponents like Senator Scott Wiener argue it balances innovation with safety, it faces opposition from major tech leaders, including OpenAI and some members of Congress, who claim it could stifle innovation and drive AI companies out of the state. Notably, Elon Musk has expressed support for the bill, emphasizing the need for regulation due to AI's potential risks. There are concerns from critics that the legislation may impose excessive compliance costs on startups. Governor Newsom has until September 30 to decide on the bill's fate.
