Microsoft CEO Nadella says AI models need an emergency brake mechanism

Microsoft CEO Satya Nadella posted on X that the trust architecture for AI needs to be reassessed; superintelligence should not be treated as a nested black box. He advocates separating models from the harnesses that orchestrate their work, placing control and safety protections externally, leaving tamper-proof human-readable evidence for every key model action, and allowing authorized parties to pause or shut down models mid-task at any time, likening this to an emergency brake.
