Elon Musk’s only AI expert witness at the OpenAI trial fears an AGI arms race

When do we take AI doomers seriously? That’s a key subtext of Elon Musk’s attempt to shut down OpenAI’s for-profit AI business. His attorneys argue that the organization was set up as a charity focused on AI safety and lost its way in pursuit of lucre. To prove that, they cite old emails and statements from the organization’s founders about the need for a public-spirited counterweight to Google DeepMind. Today, they called the only expert witness to speak directly to AI technology: Stuart Russell, a University of California, Berkeley computer science professor who has studied AI for decades. His job was to offer background on AI and establish that this technology is dangerous enough to worry about. Russell signed anopen letterin March 2023 calling for a six-month pause in AI research. In a sign of the contradictions here, Musk also signed the same letter, even as he was launching xAI, his own for-profit AI lab. Russell told jurors and Judge Yvonne Gonzalez Rogers that there were a variety of risks associated with the development of AI, ranging from cybersecurity threats to problems with misalignment and the winner-take-all nature of developing artificial general intelligence (AGI). Ultimately, he said that there was a tension between the pursuit of AGI and safety. Russell’s larger concerns about the existential threats of unconstrained AI didn’t get aired in open court after objections from OpenAI’s attorneys led the judge to limit Russell’s testimony. But Russell has long been a critic of the arms-race dynamic created by frontier labs around the globe competing to reach AGI first and called for governments to regulate the field more tightly. OpenAI’s attorneys spent their cross-examination establishing that Russell wasn’t directly evaluating the organization’s corporate structure or its specific safety policies. But this reporter (as well as the judge and the jurors) will be weighing how much value to put on the relationship between corporate greed and AI safety concerns. Virtually every one of the OpenAI founders have strenuously warned about the risks of AI, while also emphasizing the benefits, attempting to build AI as fast as possible — and hatching plans for AI-focused for-profit enterprises they would control. From the outside, a clear issue here is the growing realization inside OpenAI after its founding that the organization simply needed more compute spend if it was to succeed. That money could only come from for-profit investors. The founding team’s fear of AGI in the hands of a single organization pushed them to seek the capital that ultimately tore the team apart, creating the arms race we know today — and bringing us to this lawsuit. The same dynamic is already playing out at a national level: Senator Bernie Sanders’ push for a lawimposing a moratoriumon data center construction echoes AI fears enunciated by Elon Musk, Sam Altman, Geoffrey Hinton, and others. Hodan Omaar, who works at the trade organization the Center for Data Innovation, objected to Sanders citing their fears without their hopes, telling TechCrunch that “it is unclear why the public should discount everything tech billionaires say except when their words can be recruited to fill gaps in a precarious argument.” Now, both sides of the case are asking the court to do just that: take part of Altman’s and Musk’s arguments seriously, but discount the parts that are less useful for their legal argument. Correction: The article was updated to correct the name of Stuart Russell, University of California, Berkeley computer science professor.
