Kill switches centralize AI control

Mandating a single technical 'kill switch' for advanced AI models concentrates operational power (who can turn systems on/off) in the hands of whatever entity controls that mechanism. That centralization creates tradeoffs: it may enable emergency shutdowns but also concentrates political and commercial leverage, raising questions about verification, accountability, and the risks of delegating systemic control to private vendors or a small set of 'independent' verifiers. — How states design and whom they empower to hold 'off' switches for AI is a governance decision that affects free‑software freedoms, corporate power, national security, and individual autonomy.
