Washington (AP) — Sen. Bernie Sanders and Rep. Greg Casar are introducing legislation that would ban artificial superintelligence, pause development of advanced AI systems and create a new Department of Artificial Intelligence. The proposal comes as prominent AI executives and researchers increasingly warn about potentially catastrophic risks from rapidly advancing systems. Congress has struggled to agree on AI safeguards as President Donald Trump has pushed back on new regulations and emphasized maintaining an advantage over China. Sanders argues the potential dangers demand immediate action and international cooperation.
