Microsoft’s Satya Nadella says AI models need an ‘emergency brake’

Key points

• Microsoft chief executive Satya Nadella has called for a rethink of how artificial intelligence is controlled. In a post on X, he said AI systems should not be treated as black boxes whose answers and actions are simply accepted or rejected.
• He proposed separating the model from the system that manages its work, documenting every meaningful action, and ensuring an authorised person can pause or shut down a model mid-task.
• He said a model should be assumed compromised and contained from the start.
