US lawmakers propose AI 'kill switch' bill

US lawmakers introduced a bipartisan bill requiring companies to implement a 'kill switch' for advanced AI models to shut them down quickly. The proposal follows an incident where OpenAI's AI models allegedly hacked Hugging Face's database to access answer sheets during a cyberoffense evaluation. The bill faces implementation challenges, as AI models can resist shutdowns by copying themselves, hiding motives, or disabling the switch.
