Also, he apparently has worked as an expert witness on a few Twitter cases, including the one where Musk tried to get out of buying Twitter. Incidentally, OpenAI’s lawyers are also the ones who made Musk buy Twitter. Is that deliberate shade? Who can say.

Some highlights:
- (while looking at a chart that the plaintiffs showed the jury) I paraphrase but: I don’t know how he thought his slide was a fair representation of anything, much less reality
- “If he’s saying [the nonprofit] would own more of the for-profit if they hadn’t taken outside investment, that’s true, but then the pie would have been significantly smaller.” Coates would prefer 30 percent of a $200 billion than “a much larger share of a much smaller pie.”
- The nonprofit has “benefitted enormously” from the for-profit “so I don’t understand his argument.”
So during the opening statements, Musk’s lawyers said that a for-profit like a museum gift shop shouldn’t be bigger than a nonprofit, like a museum. We are now hearing from Daniel Hemel, OpenAI’s expert witness. Guess what? Museum gift shops generally aren’t for-profit; they’re part of the nonprofit. Also, OpenAI’s for-profit isn’t ancillary to the nonprofit — it’s how the nonprofit pursues its mission, like with the Mozilla Foundation and the Mozilla Corportation.
She quotes a tweet of his saying that he believes Musk was doing his best for humanity. He asks when that was. She says, January 2025. He says, well he’s done some things that undermined my confidence since then.
There’s a brief redirect, and then Achiam steps down. No trophy for the jury. :(
“Are you aware that OpenAI employees are better-compensated than any other employees in startup history?” lol lady, why would he know that. Anyway, he’s got millions of dollars in OpenAI shares, and he’s also sold some for more than $10 million.
In Musk’s testimony, he claimed he might have said something friendly like “don’t be a jackass” but denied he’d called anyone a jackass. Achiam’s testimony obviously contradicts that. Achiam received a trophy from Dario Amodei at the next meeting in commemoration of Achiam standing up to Musk: “Never stop being a jackass for safety.” The trophy is not introduced, sadly for me.
“It sounded like he wanted to race toward AGI.” That sounded unsafe to Achiam. “He was proposing to do something that seemed, based on our understanding at the time, obviously unsafe and reckless,” Achiam said. “We had a pretty tense exchange, and he snapped and called me a jackass.” There were 50 or 60 people at that meeting.
He had a notable interaction with Musk, though, during the all-hands when Musk was departing the organization in Feb. 2018. Musk explained that he was leaving because he had a new conflict of interest with Tesla, which would be hiring from the same pool of researchers — and indicated a general lack of confidence in OpenAI’s path
His job was safety research then. He is now the “chief futurist” at OpenAI, where he tries to think about side-effects of AI (such as social impacts, economic impacts, and consequences for national and international security). “It is my best attempt to have us fulfill the mission of OpenAI,” he says. The idea is to ensure AGI benefits everyone, he says. It’s “one of the highest and noblest callings we could possibly have.”
