The second-generation Roadster sports car was first announced in November 2017 but has been repeatedly pushed back, with Musk (Tesla’s CEO) recently saying that a new version will be unveiled by the end of this year. Musk first responded to Altman’s post by writing, “You stole a nonprofit,” a criticism that he’s directed at Altman and OpenAI before — not just in tweets, but also with lawsuits and takeover bids seeking to stymie OpenAI’s attempts to restructure as a for-profit company (a process that OpenAI recently completed, with its non-profit arm still retaining control over the for-profit public benefit corporation). Musk even started a rival AI startup, xAI, which is suing OpenAI and Apple over allegations that the two companies are colluding to stifle competition. (Altman said the accusation is “remarkable … given what I have heard alleged that Elon does to manipulate X to benefit himself and his own companies and harm his competitors and people he doesn’t like.”) In addition to repeating his criticism of Altman and OpenAI, Musk also suggested today that Altman’s screenshots didn’t tell the full story: “And you forgot to mention act 4, where this issue was fixed and you received a refund within 24 hours. But that is in your nature.” Techcrunch event
