You build a business that big and let us know what you do as CEO. I'm guessing Elon has replaced himself many times over the years with competent people. That is a skill in itself. Finding and managing competent people is a skill.In fact can we just admit that most CEOs don't do much real work for their companies? Seems like their real jobs are to hoover up money and talk about how great they are while shitting all over their workers.
