Elon Musk has publicly supported California's SB 1047, a proposed bill regulating artificial intelligence. The bill would require AI developers, particularly those investing over $100 million in building AI models, to conduct safety testing, implement safeguards, and establish protocols for emergency shutdowns. It also allows the state attorney general to pursue legal action if their AI models cause significant harm, such as mass casualties or $500 million in damages. Musk acknowledged the decision's difficulty but emphasized the need for regulation to prevent risks associated with AI.
