Elon Musk takes a dig at Sam Altman saying he'll have to use Microsoft Teams after he was fired on Google Meet

• Elon Musk poked fun at Sam Altman and OpenAI following his shock departure.
• Altman was fired by the board over Google Meet, despite Microsoft investing billions in OpenAI. 
• Musk, who has warned about the risks of AI, has said the board should explain its "drastic" action.

Just like the rest of us, Elon Musk can't stop watching the drama around Sam Altman and OpenAI — and now he's poked fun at the AI startup and its former CEO after he was fired over a Google Meet.

"Now they will have to use Teams!" Musk wrote in a reply to Microsoft CEO Satya Nadella's announcement that Sam Altman and Greg Brockman would be joining the company — a reference to the fact that OpenAI's board apparently relies on Google's video calling tech, despite Microsoft investing $10 billion in the AI startup.

Musk seems to have been reveling in the drama surrounding the firing of Altman. The two helped start OpenAI together in 2015, but Musk left in 2018 and later slammed the company over its deal with Microsoft.

The Tesla CEO has been in an online spat with Altman in recent weeks after the ex-OpenAI CEO poked fun at Grok, the AI model built by Musk's company xAI, which he set up earlier this year to compete with OpenAI.

Altman was fired by OpenAI's board on Friday, after board members said he had not been "consistently candid" in his discussions with them.

It has been reported that one of the potential reasons for Altman's firing was the growing tension between OpenAI's commercial push spearheaded by Altman and parts of the company that were concerned about the dangers posed by AI technology.

Elon Musk has expressed similar concerns in the past, and has called on the board to explain its reasoning for firing Altman.

"Given the risk and power of advanced AI, the public should be informed of why the board felt they had to take such a drastic decision," he wrote in a reply on X on Sunday.
