Musk's AI Expert Warns of AGI Arms Race at Trial

Elon Musk's lawsuit against OpenAI called its only AI technology expert witness, UC Berkeley professor Stuart Russell, to testify about the dangers of artificial general intelligence. Russell warned jurors of an AGI arms race among frontier labs and the tension between safety and unconstrained AI development, though the judge limited his broader existential risk testimony. The trial highlights a central contradiction: OpenAI's founders, including Musk, have long warned about AI dangers while simultaneously racing to build it. OpenAI's attorneys countered that Russell was not evaluating the organization's specific corporate structure or safety policies.
