Elon Musk and Sam Altman facing off
  • Elon Musk is suing OpenAI and its CEO, Sam Altman, years after leaving the startup.
  • Despite Musk's allegations, legal experts say his case against OpenAI appears weak.
  • But Musk's lawsuit could still hamper OpenAI, tying it up in court and airing dirty laundry.

It was last May, and Elon Musk was sitting down for an interview with CNBC's David Faber.

When asked about Altman and OpenAI, Musk grew visibly frustrated.

"It wouldn't exist without me," Musk said.
