No idea. Elon Musk is a capitalist with a fanbase to me. Ancaps love him to pieces and since I deal with ancaps a lot online, that’s how I know about him.
But it’s just as likely I wouldn’t know much about him otherwise. I don’t know if he’s influential or not worldwide.
I know Tesla is because electricity spans the globe for almost 200 years and the battle between AC and DC is well known worldwide. Tesla represents the Electric (even though it should be Westinghouse) and Edison the DC. Tesla the Geek and Edison the Entrepreneur.
These are universal themes.
