Musk is a bullshitter who has bootstrapped his way to success, admittedly successfully. However, when you look at his well covered statements (too darned many of them :) post-Twitter, it’s obvious that he, for example, knows nothing about software, datacenter admin, nor the world of advertising. I’m willing to extrapolate to believe that he knows little more than the veneer of science and technology that’s necessary to persuade others to finance him.
