OpenAI president's journal entries take center stage
The second week of the Musk v. Altman trial began Monday in federal court with attention shifting from Elon Musk to co-defendant and OpenAI President Greg Brockman, as jurors heard testimony centered on Brockman's personal journal entries and debates over OpenAI's original nonprofit mission.
Musk was not in court, and the atmosphere outside the Oakland courthouse was noticeably calmer, with fewer protesters and smaller crowds. Inside, Musk's attorneys focused their questioning on Brockman, portraying him as motivated by money and drawn to Musk's influence during OpenAI's early years. At one point, Brockman was asked whether he was honored to work alongside Musk.
Marc Toberoff, an attorney for Musk, said, "Monday was a strong day in court."
Musk's legal team has long pointed to Brockman's journals as key evidence, arguing they show Brockman and co-defendant Sam Altman misled Musk about maintaining OpenAI as a nonprofit organization.
"In particular, Mr. Brockman's testimony and his journal, in his own unfiltered words, reinforce our confidence in our claims, and we look forward to continuing to build on this progress as the case proceeds," Toberoff said.
One 2017 journal entry introduced in court shows Brockman writing: "Financially, what will take me to $1B?" On the witness stand, Brockman testified that his stake in OpenAI is now worth nearly $30 billion. Musk's attorney pressed Brockman on what motivates him and why he didn't donate the difference of $29 billion back to the nonprofit.
William Savitt, an attorney for OpenAI, objected to that line of questioning, calling it "Theatrical grandstanding questions completely irrelevant to the lawsuit."
Toberoff honed in on that part of the testimony, adding of Brockman: "He's speaking as the director and officer of a nonprofit, a publicly subsidized nonprofit, and he's writing secretly. How do I get to $1 billion?"
Questioned about OpenAI's original charter, Brockman testified that its stated mission to serve humanity through artificial general intelligence remains intact.
"I think it is still accurate," Brockman said, adding, "I do stand by this is what we've been doing."
He denied breaching any duty to humanity, arguing the company's current structure has produced what he called "the most well-resourced nonprofit in history."
Brockman acknowledged that Musk personally helped OpenAI recruit top talent in its early days and said some prospective hires were often eager to meet Musk. He agreed that Musk's involvement lent OpenAI credibility and said some candidates were drawn to the opportunity to work alongside him. In a January 2018 email shown to the jury, Brockman wrote to Musk that it was an "honor to work alongside him," a statement Brockman confirmed on the stand.
Jurors also heard from UC Berkeley professor Stuart Russell, who testified as an expert witness on artificial intelligence risks. The judge, however, already barred any discussion of existential threats related to AI. Russell disclosed he was paid $5,000 an hour for his work on this case, totaling roughly $250,000, or about 20% of his annual earnings.
A newly revealed court filing shows Musk and Brockman exchanged text messages two days before the trial, discussing a possible settlement. After talks fell apart, Musk texted Brockman: "By the end of this week, you and Sam will be the most hated men in America. If you insist, so it will be."
The judge has ruled that those texts are not admissible at trial.
As Brockman's testimony began, the attorney said, "And now he has the opportunity to tell his story, which he's going to do tomorrow, and it'll be the story that will carry the day, because it's the story that is true, which is that it's a complex organization and a complex problem."
At one point Monday, Brockman defended his journal entries, describing them as expressions of frustration rather than a concrete plan. Musk's attorney pushed back, asking how often Brockman had rehearsed that explanation before taking the stand.
Brockman is expected to return to the witness stand on Tuesday as the trial continues in Oakland.
