Stuart Russell Testifies in Musk v. OpenAI, Warns of AGI Arms Race

ai-technology · 2026-05-04

During the trial of Elon Musk v. OpenAI, Stuart Russell, a computer science professor at the University of California, Berkeley and the sole expert witness on AI, shared insights on the perils of unregulated artificial intelligence. In March 2023, he co-signed an open letter advocating for a six-month halt on AI research, which Musk also endorsed while establishing his for-profit AI venture, xAI. Russell highlighted various risks, such as cybersecurity issues, misalignment, and the competitive nature of developing Artificial General Intelligence (AGI), stressing the conflict between pursuing AGI and ensuring safety. OpenAI's lawyers restricted Russell's testimony through objections, barring discussions of existential risks. The trial focuses on Musk's assertion that OpenAI has deviated from its original mission as a charity dedicated to AI safety. This situation reflects a broader tension among AI founders who express concerns about risks while simultaneously advancing AGI, a scenario echoed by Senator Bernie Sanders’ proposed moratorium on data center construction due to similar apprehensions.
