According to CoinMeta, on September 3, Senator Bernie Sanders and Representative Greg Casar's office announced a bill aimed at permanently banning artificial superintelligence, suspending the development of advanced AI, and imposing up to 20 years in prison on violators. The bill prohibits the development and deployment of AI systems classified as superintelligence, and suspends work on advanced AI models until new federal regulatory agencies establish safety rules. Supporters of the bill hope that the United States can reach international agreements with allies to prevent other countries from developing superintelligence. The bill summary states that artificial superintelligence includes systems that match or exceed human cognitive performance in a wide range of tasks and can be easily modified to achieve that level. Sanders stated that if major AI companies lose control of their dangerous technologies, society should not allow them to continue advancing these products.
