A trial is underway involving Elon Musk and OpenAI, with Musk testifying against the company and its leader, Sam Altman. The judge has issued warnings to lawyers, including a reminder that the trial is not about the technology of AI itself, and has also cautioned them about their conduct in court. The case appears to involve allegations of wrongdoing, including claims that Altman stole a charity, and has touched on broader concerns about the risks of AI to humanity.
