Tech billionaire Elon Musk, whose social media platform Twitter is currently building a competition to OpenAI’s ChatGPT, recently voiced his concerns over the artificial intelligence, to a point that he has suggested government to regulate it.

“AI stresses me out,” Musk said near the end of a more than three-hour presentation to Tesla investors about company plans.

At the event, the world’s richest man was asked if AI could help Tesla build cars. The Twitter chief wasn’t optimistic. “I don’t see AI helping us make cars any time soon,” he said. “At that point … there’s no point in any of us working.”

Earlier this week, Musk had appeared to confirm via Twitter reports that he is recruiting a team of AI technologists to build a competitor to OpenAI’s text-based ChatGPT.

ChatGPT, which has been making serious noise across social media platforms ever since it made its debut, is backed by Microsoft Corp. Not only at Twitter, but similar AI-related systems are under development at Alphabet Inc’s Google, Meta Platforms Inc and other large technology platforms.

According to a report in the Information, Musk has approached AI researchers in recent weeks about forming a new research lab to develop an alternative to ChatGPT.

Tesla and Twitter chief Musk has been recruiting Igor Babuschkin, a researcher who recently left Alphabet’s DeepMind AI unit, the report said.ChatGPT is a text-based chatbot developed by OpenAI that can draft prose, poetry or even computer code on command. Musk, who had co-founded OpenAI along with Silicon Valley investor Sam Altman in 2015 as a nonprofit startup, had left its board in 2018, but chimed in with his take on the chatbot, calling it “scary good”.

In December last year, Musk had said that humans “are not far from dangerously strong AI.” He amplified those concerns for the audience of Tesla analysts Wednesday.

“I’m a little worried about the AI stuff,” Musk said at the event held on Wednesday. “We need some kind of, like, regulatory authority or something overseeing AI development,” Musk said. “Make sure it’s operating in the public interest. It’s quite dangerous technology. I fear I may have done some things to accelerate it.”
