OpenAI employees threaten to resign if current board doesn't quit, following former leader Sam Altman to Microsoft. About 600 of OpenAI's 770 employees signed a letter expressing concern over the competence, judgment, and care of the current board. Microsoft, which owns nearly half of OpenAI, plans to bring Altman and co-founder Greg Brockman to lead a new AI research team. #finance #tech #engineering #ai #startups #business
