It's possible he's special, but you often see the pattern that someone starts a highly successful company, but then go on to start other companies that don't do well. That they can't replicate their success suggests luck or circumstance was involved.

And there is always the possibility that the CEO wasn't the one to make the company successful. A company isn't one person.

Mainly because some people loathe the idea that they aren't entitled to a share of what Bezos created so they prefer to view his success as something anyone could have done if only for xyz.
