California Governor Gavin Newsom has vetoed SB 1047, a landmark AI safety bill, citing concerns that it would stifle innovation and create a 'false sense of security' by targeting only large-scale AI models. The bill, championed by Senator Scott Wiener, would have mandated safety tests, public disclosure of safety protocols, and the implementation of 'kill switches' for advanced AI systems. Newsom's decision has sparked a heated debate, with industry leaders celebrating the move as a win for innovation, while AI safety advocates and some lawmakers criticize it as a missed opportunity for effective regulation. Despite the veto, Newsom has signed other AI-related bills and announced plans to seek expert input for future AI safeguards. The veto highlights the ongoing struggle to balance technological advancement with regulatory oversight in the rapidly evolving AI industry.
