Microsoft CEO Nadella calls for AI systems to be equipped with human-controllable "emergency brakes"

Microsoft CEO Satya Nadella says advanced AI systems should have built-in isolation mechanisms, independent control, and an "emergency brake," allowing authorized personnel to pause or shut down a model mid-task. He proposed that systems be designed around observability principles, including model diversity, human-readable behavior traces, continuous system testing, independent control and auditability, isolation, and incident disclosure, and managing frontier closed-source and open-weight models as internal risks.
