Satya reverted the course spectacularly - and most importantly, he did NOT miss the "once-in-a-lifetime" opportunity which he had. Unlike Billg (who missed the dawn of the Internet) and the chair-throwing dude (who fumbled Mobile), Satya is making sure Microsoft does NOT miss AI. Which is even more impressive as Google was kind of expected to be the winner initially, given the whole company's focus , mission statement ("to organize the world's information and make it universally accessible and useful") and a considerable (at the time) lead, if not a moat.
I dare to compare his turnaround to Jobs'. Sure, MSFT wasn't weeks away from insolvency when he took over, and some of their current successes were indeed started before his tenure, but just look at where Windows 8 was going.
*Edit: Just as a clarification: Not an employee, I actually dislike them profoundly and would never join them. I'm not sure this move is the best outcome for mankind - but credit where credit's due, they were shrewd, smart and right on time. Hats off.
