Also keep in mind that Microsoft hasn't actually given OpenAI $13 Billion because much of that is in the form of Azure credits.
So this could end up being the cheapest acquisition for Microsoft: They get a $90 Billion company for peanuts.

Why would anyone in their right mind invite such a man to lead a commercial research team, when he's demonstrated quite clearly that he'd spend all his time trying to sabotage it?
This idea that he's one of the world's best researchers is also somewhat questionable. Nobody cared much about OpenAI's work up until they did some excellent scaling engineering, partnered with Microsoft to get GPUs and then commercialized Google's transformer research papers. OpenAI's success is still largely built on the back of excellent execution of other people's ideas more than any unique breakthroughs. The main advance they made beyond Google's work was InstructGPT which let you talk to LLMs naturally for the first time, but Sutskever's name doesn't appear on that paper.
