Stuart Russell, UC Berkeley AI safety researcher, testifies as Musk's expert witness in OpenAI lawsuit, citing risks of AI arms race and AGI competition

Stuart Russell, a University of California, Berkeley computer science professor who has studied AI for decades, testified as an expert witness in Elon Musk's case against OpenAI. Russell co-signed an open letter in March 2023 calling for a six-month pause in AI research.

Russell told the court that risks associated with AI development range from cybersecurity threats to misalignment and the winner-take-all nature of developing Artificial General Intelligence (AGI). He stated there is a tension between the pursuit of AGI and safety, and has long criticized the arms-race dynamic created by frontier labs competing to reach AGI first.

OpenAI's attorneys limited Russell's testimony through objections upheld by Judge Yvonne Gonzalez Rodgers, and established during cross-examination that Russell was not directly evaluating the organization's corporate structure or specific safety policies.
