I think that your reasoning can be applied to a lot of people, independently from the "above average smart" condition. Still, I believe that one can both recognize Musk's abilities and give due credit to the people in the company.

As for being at the right place/time, I hope you agree with me in saying that success is a mix of hard work and luck. But again, this is not the point of my first comment.

Btw, I had a hard time understanding what you wrote so forgive me if I got the wrong meaning out of it.
