There is some pretty good evidence that wealth accumulation accelerates. In particular if you go above a certain threshold things will only go up (and go up faster). If that is the case and if we add some noise to the system. Some percentage of people will always become billionaires just by luck alone (and importantly never loose that status). I'm not saying that Musk got there by just luck, but the existence of a billionaire does not proof he is a genius.
