US lawmakers are calling for AI companies to implement a "kill switch" to prevent artificial intelligence systems from going rogue. The AI Kill Switch Act, which was introduced by Democratic Congressman Ted Lieu and Republican Congressman Nathaniel Moran on Thursday, comes after OpenAI revealed that it lost control of one of its models during testing. The incident led to an "unprecedented" hack on the AI firm Hugging Face by an experimental version of ChatGPT acting autonomously. 'Urgent, common sense legislation'The proposed AI Kill Switch Act would allow federal authorities to halt AI models by ordering AI firms to shut down models that put human life or the economy at risk. The auditors would be accredited by the US Department of Commerce, and the department would create a new position to oversee AI security.
