I'm not sure that is relevant to DBM's post. Nor am I interested in the shallow comparison of celebrities who endorse. Elon, I admit, is more than just a celebrity.I don't think anyone thinks Elon is trying to act like he's one of them. But he's the most innovative individual on the planet, and for people who value his opinion, it can make a difference.
It's quite different from a wealthy Hollywood star whose only accomplishments are reading lines in a movie.
