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.

I don't see a trajectory to "head of Microsoft Research".
Their asset isn't some kind of masterful operations management and reign in cost and management structure as far as I see. But about the fact they simply put, have the leading models.
So I'm very confused why would people want to following the CEO? And not be more attached to the technical leadership? Even from investor point of view?
