California: Tesla CEO Elon Musk, the world’s richest man and co-founder of OpenAI, took the stand on Tuesday (US time) in a high-stakes trial involving a bitter feud between himself and former friends Sam Altman and Greg Brockman that could change the future development of artificial intelligence.
The feuding billionaires’ appearance in federal court in Oakland heralds the start of a legal drama that is expected to be full of intrigue and potentially embarrassing details about the two tech moguls. Musk, along with Microsoft, filed a lawsuit against Altman and Brockman in 2024 over his investments in OpenAI.
The civil lawsuit claims Musk is the richest person in the world with an estimated fortune of $778 billion ($1.08).
