Sam Altman Returns as OpenAI CEO. Here's How It Happened

Over five chaotic days that transfixed Silicon Valley and beyond, the world's leading artificial intelligence company, OpenAI, appeared to be on the verge of imploding in a power struggle. The maker of ChatGPT, the sensational chatbot, had a mission to safely develop smarter-than-human AI. But that mission looked in jeopardy on Friday when OpenAI's non-profit board of directors fired Altman, suggesting he had been dishonest in his communications with them. To many spectators, the future of not just AI but also humanity hung in the balance. Finally late on Tuesday night, after three CEO changes and a full-court press by Microsoft, the board gave Altman his old job back.
