I don't have a whole lot to add. I find it hard to believe people would consider Elon stupid and that the author feels it necessary to take anyone seriously that did.
I understand there's partisan hate for Elon, and I get that he's duplicitous at levels mostly proportional to his wealth and agency (king kong takes bigger smellier shits), but he is undeniably one of the most entrepreneurially industrious and generative people alive, right?
