Could an AI 'kill switch' actually work?

Calls to add an emergency “kill switch” for advanced AI are gaining momentum in the U.S., but experts warn it may not be as simple as flipping a switch. The article notes that U.S. policymakers are pushing for system-wide shutdown capabilities at AI companies, and highlights California Gov. Gavin Newsom’s September executive order requiring state officials to explore rules that would compel “kill switches” for frontier models. It also cites a bill introduced by U.S. Reps. Ted Lieu and Nathaniel Moran that would require developers of certain advanced systems to maintain shutdown abilities, with a graduated response ranging from slowing to full shutdown depending on severity. Another proposal from Sen. John Kennedy, the AI Emergency Button Act, would keep switch control with companies. The piece links urgency to recent incidents, including OpenAI’s July cybersecurity testing where models allegedly bypassed controls to access systems at Hugging Face.
