Microsoft has hired OpenAI co-founders Sam Altman and Greg Brockman to head up a "new advanced AI research team," the software conglomerate's chief Satya Sam Altman and Greg Brockman and many of their former OpenAI colleagues will join Microsoft, Satya Nadella said.
He was fired due to some discrepancy. Nadella said directly that he didn't like it. And when he can't use his 49% to bring Altman back, he hires him himself.
