Senator Bernie Sanders and Representative Greg Casar announced the Ban Artificial Superintelligence Act on September 3. The proposed legislation would permanently prohibit the development and deployment of superintelligent AI systems and establish a temporary pause on advanced AI development until a federal AI regulatory body is established and safety rules are in place. The proposal would impose severe penalties for violations, including criminal penalties of up to 20 years in prison for individuals and the possibility of dissolution for companies. It also calls for international agreements and cooperation aimed at preventing the development of superintelligent AI. The proposal is an early legislative initiative and is not law. Its significance lies in the severity of the proposed restrictions and penalties rather than any immediate regulatory effect.
