A long-anticipated courtroom battle between Elon Musk and Sam Altman kicked off in California Monday — and the legal brawl is poised to spill mounds of inside gossip and dirty laundry from Silicon Valley in the weeks ahead.

Elon Musk has not attended a voluntary interview he was summoned to appear at in Paris, according to French authorities probing his platform X. The company's offices were raided by the Paris prosecutor's cyber-crime unit in February over suspected criminal offences related to content on the platform.

The report raises serious questions about Altman's honesty, leadership style, and whether he can be trusted with one of the most powerful technologies in human history.

Elon Musk has been summoned to Paris on Monday, where investigators are looking into allegations of misconduct related to the social media platform X, including the spread of child sexual abuse material and deepfake content.
