Nadella changed the focus and direction of Microsoft. The company increased in value 10x. Maybe "anyone could have done that", in hindsight. Heck, if I went back in time with a detailed copy of Apple's history, I could have done what Jobs did.
But without that guide, I would have destroyed Apple. I'm just not that good.
All I am saying is we don't know that it was his decisions that caused the value increase and not something else, and we can't know because we can't do a controlled experiment in another otherwise identical universe to rule out other factors.
