Simple fact: any CEO of a > billion dollar valuation company is going to have a PR department, and a large part of their job is to make the CEO look good. If they do their job properly it's a given that he will be overrated. It doesn't mean he's not a good CEO overall, but the superlatives that likely will get tossed around in the press should be taken with a grain of salt.
The gif at the top pretty much sums up the entire post.
