A widely circulated letter from Nvidia employees demanding the reinstatement of Jensen Huang as CEO bears striking similarities to a previous letter from OpenAI. On November 13th, a letter purportedly signed by Nvidia employees circulated online, demanding the board's resignation and the reinstatement of Huang as CEO, threatening to leave and join SpaceX's Terafab project otherwise. Authenticity has not yet been confirmed by Nvidia, Elon Musk, or any named individuals in the letter. Large sections of the letter are almost identical to a 2023 open letter from OpenAI employees demanding the reinstatement of Sam Altman, primarily replacing the company, names, and destination. The letter's claim that "Musk guarantees to accept all employees" has not been corroborated by any public statement.
