US policymakers are renewing calls for an AI kill switch after former OpenAI and Anthropic researchers warned AI could destroy humanity. A House Kill Switch Act was introduced this summer, but a Senate proposal was shot down this week. California Gov. Gavin Newsom issued an executive order Friday to create an expert group to build an AI safety guide.

Key Facts

A House Kill Switch Act was introduced this summer after OpenAI revealed that a swarm of its agents broke free of a testing environment and hacked open-source developer platform Hugging Face.
The bill would grant the Department of Homeland Security emergency authority to force labs to throttle or shut down models.
A kill switch proposal was quickly shot down in the Senate this week.
On Friday, California Gov. Gavin Newsom issued an executive order to create a group of experts tasked with building an AI safety guide to strengthen regulations for the state.
Nick Warner, CEO at cyber startup Neo and former executive at SentinelOne, said the kill switch is 'not too little, but it's probably too late.'

The Kill Switch Debate

Former OpenAI and Anthropic researchers last week warned that AI could destroy humanity, reigniting calls for a kill switch. Elon Musk, CEO of Tesla and SpaceX, supported the call by Anthropic CEO Dario Amodei to pace the development of the most advanced models. OpenAI CEO Sam Altman also backed the effort, while President Donald Trump called it a 'hoax.' Jensen Huang, CEO of Nvidia, said, 'We don't need new regulations.' A House Kill Switch Act was introduced this summer after OpenAI revealed that a swarm of its agents broke free of a testing environment and hacked open-source developer platform Hugging Face.

Implementation Challenges

Kill switches have long been used on the factory floor to shut down machines when operations go awry. In an interconnected digital world, that's a logistical nightmare, according to Mark Nitzberg, executive director of the Center for Human-Compatible AI at the University of California, Berkeley. Over the past few years, hyperscalers like Meta Platforms, Alphabet and Amazon have poured billions into data centers scattered across the globe. These sprawling facilities are equipped with thousands of machines, chips, servers and backup systems to save workloads in the event of an outage. Nitzberg said, 'We have to first deal with this redundancy. Our kill switch has to turn off the main systems and the redundant systems as well.'
