He bought a company that got bought by PayPal. He didn’t build anything he didn’t run anything. He bought an existing company that got bought out. At SpaceX and Tesla they have entire structures created to stop Elon from fucking up shit and to manage him. If you need your company organized to manage the owner and stop them from fucking shit up you don’t get to claim to be smart or to build amazing stuff.
