Elon Musk spent three days testifying as the first witness in his trial against OpenAI.

Musk’s lawsuit challenges OpenAI’s evolution under Sam Altman. But during jury selection, several potential jurors voiced negative views of Musk himself.

The judge also warned Musk and Sam Altman to curb their “propensity to use social media to make things worse outside the courtroom” after both sides traded attacks online.
