It’s been a chaotic few days for the folks at OpenAI, including now-former CEO Sam Altman. To recap, on Friday the company’s board announced it had let Altman go, citing a lack of confidence in his “ability to continue leading OpenAI.” Several staff members then resigned and hundreds of others threatened to do the same if Altman wasn’t reinstated as CEO. That option is pretty much moot now that Microsoft — a major OpenAI investor — has hired Altman to lead a new AI research team along with former President Greg Brockman, who resigned in solidarity.
