My take on celebrity CEOs is that they are likely terrible as political leaders for all the right-side-of-the-brain, damn-the-process, lets-build-a-barn-and-put-on-a-show, stuff.
I get that people love them some Elon Musk. The Earth to Mars tv show, Twitter and other social media has been coaching me for years on how great he is. Henry Ford would have been shit as a political leader. I'm not down with that model of leadership at least until the current unpleasant experiment in fascist demagoguery passes away into the dustbin of history.
