Following high-profile testimony from billionaire Elon Musk last week, one of OpenAI's co-founders testified Monday in the California lawsuit brought by the world's richest man against the creators of ChatGPT.
Musk's lawyers called Greg Brockman to the stand in an effort to show the jury that OpenAI's founders manipulated their original benefactor to transform a philanthropic mission into a money-making enterprise worth hundreds of billions of dollars.
