Microsoft's corporate structure and company culture is actively hostile to innovation of any kind. This was true in Ballmer's era and is equally true today, no matter how many PR wins Nadella is able to pull off. The company justifies its market cap by selling office software and cloud services contracts to large corporations and governments via an army of salespeople and lobbyists, and that is what it will continue to be successful at. It got lucky by backing OpenAI at the right time, but the delusion of becoming an independent AI powerhouse like OpenAI, Anthropic, Google, Meta etc. will never be a reality. Stuff like this is simply not in the company's DNA.
