AI bigwigs want to go all-in on nuclear. They also happen to be behind nuclear companies

OpenAI CEO Sam Altman and Microsoft founder Bill Gates now chair nuclear energy startups. Many tech leaders say nuclear will be necessary to power their AI ambitions.

Sam Altman is the chairman of a company that promises a brighter future for humankind.

No, it’s not OpenAI, the artificial intelligence company he co-founded and now runs as CEO.

It’s a company called Oklo, and it’s developing the kind of nuclear power technology that many tech leaders — including Altman himself — say they will need to fuel future artificial intelligence advancements.

The proliferation of electricity-hungry data centers to power our digital lives – and increasingly, the AI technology that tech giants say is the future – now means that energy demand could soon outstrip supply. And that would be a problem for tech companies who are angling for their AI technology to revolutionize almost everything about the way we live and work.
