Lawyers for Elon Musk have claimed that the billionaire “does not use a computer” after OpenAI accused Musk of not complying with the discovery process in his lawsuit against the company.

In a letter addressed to the judge overseeing the OpenAI case in Oakland, Musk’s attorney, Jaymie Parkkinen, accused OpenAI of making false statements when the company asserted that Musk’s legal team had “no plans to collect any documents” from either Musk himself or xAI, his competing artificial intelligence firm.

In the letter, Parkkinen disputed this claim, saying the lawyers for Musk had informed OpenAI that searches were being conducted on Musk’s mobile phone and that the billionaire didn’t use a computer.

“Plaintiffs sent Defendants a letter informing them that Plaintiffs were conducting searches of Mr. Musk’s mobile phone, having searched his emails, and that Mr. Musk does not use a computer,” the filing reads.

There are several pieces of public evidence to suggest that Musk does indeed have a computer.
