I can guarantee you that many billionaires will be looking at Elon Musk with abject terror.
Contrary to what his stans will tell you, the most notable thing about Elon is not his wealth, competency or ingenuity. His overriding feature is his boundless narcissism. The wealthy are highly class conscious. Entire fields, marketing, PR etc. have arisen to launder and filter the public image of these people, because they know all too well that real, unconsolidated power lies in the masses who could be galvanised if the unwarranted privilege of the ruling class was properly known.
Elon is completely fucking the whole thing up. Think about how many billionaires there are. How many of them have known faces, names or legacies? There is a reason most of these people eschew the limelight, and it's because they want to avoid precisely the kind of bad publicity that Elon is receiving.
Keep talking about him. Keep highlighting his daddy's slaves paid for with diamonds, his lack of technological credentials, his union busting, his complete hypocrisy vis a vis free speech, his kid who hates him, his failed relationships.
These are the people that our culture celebrates and enriches, so let them expose themselves, and don't let people like Mark Cuban, an partial exception to the rule, become the public face of the billionaire class. He is not representative and I won't be surprised at all if positive media about him begins to proliferate.
