An employee told me he was quitting to join OpenAI in 2016. I said it was a bad idea. Now he’s an AI billionaire.

• Jack Clark was a reporter at Bloomberg when I was an editor there.
• He told me he was quitting to join OpenAI in 2016.
• I told him that was a terrible idea. The rest is history.

In 2016, Jack Clark walked up to me in Bloomberg’s San Francisco newsroom and asked if we could go for a walk. As an editor, it’s often not good when one of your reporters makes a request like this.

Sure enough, as we sat on a bench looking over the Bay Bridge, Jack told me he was quitting to join a nonprofit called OpenAI.

I said this was a terrible idea. OpenAI was less than a year old at the time and was still a relatively obscure AI research group. Its major claim to fame was Elon Musk‘s (uneven) financial support.

I pressed my case. As a reporter on Bloomberg’s Big Tech team, Jack had a pretty stable job. In contrast, OpenAI didn’t seem to have much of a direction, and I couldn’t see a path for it to become financially sustainable beyond asking Musk for more money. I selfishly also wanted Jack to stay at Bloomberg and keep covering Google and AI, which he was good at.

I thought I was pretty persuasive, but Jack ignored me and left.

“Just read the research papers”

He went on to be an influential expert and advisor on AI safety and related topics, co-authoring several AI research papers. Jack also built one of the most popular AI email newsletters, called Import AI, which researchers widely follow in the field. He still writes this regularly.

He often told me to “just read the research papers” when I asked how to learn more about AI and get better stories about the technology. He was right. There’s a lot of valuable information buried in these papers.

Jack stayed at OpenAI for over four years, doing strategy and communications before becoming a policy director. He may have gotten some equity in that startup, but I’m not sure.

Then, in 2020, he left OpenAI and I didn’t hear from him for a while. He popped up a few months later as one of seven cofounders of Anthropic, which was started by a bunch of early OpenAI employees.

Cofounders reminisce

Anthropic is now challenging OpenAI at the forefront of generative AI and large language models. It’s backed by Amazon and Google, along with several top venture capital firms.

The cofounders got together last month to talk about the start of Anthropic. Jack holds court with his colleagues, who reminisce about the early days.

“I met Dario in 2015 when I went to a conference you were at, and I tried to interview you, and Google PR said I would’ve read all of your research papers,” Jack says to Dario Amodei, CEO of Anthropic, who used to work at Google.

“I think I was writing ‘Concrete problems in AI safety’ when I was at Google,” Amodei replies. “I think you wrote a story about that paper.”

“I did,” Jack says, with a cheeky smile.

Not his style

Earlier this month, the Wall Street Journal reported that Anthropic was raising money at a $60 billion valuation. Then, Forbes reported that the seven cofounders, including Jack, are set to become billionaires.

I asked Jack about this last week and said I wanted to interview him for a story. 

“Haha, Ali, thanks, but really not my style,” he replied.

It’s true. Jack is among the gentlest, kindest, and most self-deprecating people I’ve ever met. He’s not classic billionaire material. 

I’m still stunned and trying to process his new situation. What I do know is that Jack’s decision to ignore me was a testament to his passion, single-mindedness, and vision.

Back in 2015, when very few people thought about AI, he was obsessed with it and was constantly pushing to write about the technology at Bloomberg. 

Jack knew that AI was important. When his chance came, he took a risk and went for it.
