OpenAI unexpectedly dismissed its CEO, Sam Altman, over the weekend, leading to a potential brain drain crisis for the company. Altman has since joined Microsoft as the CEO of a newly established artificial intelligence division. Accompanying him are the President of OpenAI and its core engineering team. OpenAI employees have collectively signed a letter demanding Altman's reinstatement, threatening to resign en masse otherwise. Microsoft has pledged to offer jobs to all OpenAI employees willing to join. This could potentially weaken OpenAI's leading position in the AI field but strengthens Microsoft's AI capabilities.
