OpenAI's CEO Sam Altman was fired in a surprise move by the company's board, reportedly due to disagreements over the speed of commercialization and concerns about safety. The board's decision was allegedly orchestrated by Chief Scientist Ilya Sutskever, who had been arguing for a slower approach. The move has led to the resignation of several key employees, including President Greg Brockman and three senior scientists. Microsoft, a key investor, is said to be furious about the decision.
