Elon Musk has expressed his support for California's Senate Bill 1047, which mandates safety testing and documentation for large AI models, citing the need for regulation to prevent potential risks to the public. Musk's backing comes amid concerns from tech giants like OpenAI, who argue the bill could impose vague and burdensome regulations that stifle innovation. The bill, authored by state Senator Scott Wiener, aims to establish safeguards against the misuse of powerful AI technologies and would create a new agency for oversight. Musk acknowledged that his endorsement could upset some, but emphasized the importance of balancing innovation with safety. As the bill progresses through the legislature, it highlights the ongoing debate over the regulation of AI in California and beyond. If passed, it would require large AI developers to assess and report the risks associated with their technologies.
