I think for some CEOs it is actually applicable. Bezos being one of them. He has build Amazon from scratch. Sure he hired lots and lots of people to help him. But hiring the right people at the right moment is not easy and very, very important. Many startups fail at exactly that point.
I think Bezos is great and probably the right person but I also think Amazon was inevitable. If it wasn't Bezos it would've been someone else. Maybe not in 1994 but shortly thereafter. Amazon is not invincible either. They started amazon.cn in 1998 but they are now shutting down that division/business.
