I think Elon Musk just wants to be Tony Stark and cultivates the appropriate image for that.
And possibly a genuine obsession with (rightwing-ish) meme/youth culture, which I think got him a lot of his initial followers on twitter/reddit/4chan/etc.
A lot of people miss how much of a tit Tony Stark (at least the Robert Downey Jr. version) was.
Smart, but not as smart as he thinks he is. Not good with anything interpersonal. Flair for the dramatic (and dad jokes) at the expense of those working with him.
Is there a difference? I mean, he may be Tony Stark to himself but end up an oppressor to others.
Musk is a complicated character. He's had nerdy times programing, fascist turns including the famous salute, emperor delusions - he was named after The Elon, a fictional ruler of Mars.
He thinks he's Tony Stark but he's actually Justin Hammer.
