After a flurry of weekend negotiations, Microsoft said it hired Sam Altman — just two days after the board of OpenAI abruptly ousted him as CEO — while OpenAI recruited Emmett Shear, most recently chief executive of livestreaming platform Twitch, to step in as interim CEO. Altman will lead a new artificial-intelligence research team at Microsoft, alongside former OpenAI president Greg Brockman (who had quit after Altman was fired on Nov. 17).
