Have a look at this MS revenues [1] and consider why for a moment there is any 'conventional wisdom' like this?
MSFT stock price did languish during this time of amazing growth which I guess validates that 'conventional wisdom' was in fact sour, but it's hard to see why it was.
Robert Shiller, in a recent interview on the FT alphaville podcast [2] indicated how so much of valuation was based on 'narrative' and that a lot of this narrative is in fact fiction.
For whatever reason, the industry press never liked Ballmer, and I guess they like Satya. Surely, there have been some changes afoot, but in terms of fundamental business orientation, I don't see any reason why Satya is 'better than' Ballmer. At HN, we might see things like VS Code and open sourcing Chakra as 'important', and although they are relevant, those issues are small peanuts in the MS bigger picture.
