Altman reporting to Nadella is certainly going to be a fascinating political struggle!

Part of me thinks that Nadella, having already demonstrated his mastery over all his competitor CEOs with one deft move after another over the past few years, took this on because he needed a new challenge.

I'd wager Altman will either get sidelined and pushed out, or become Nadella's successor, over the course of the next decade or so.

It's an interesting time!
