You're bad mouthing someone who regularly lands rockets on ships in the ocean and has bootstrapped the first electric car company. I think Elon deserves the benefit of the doubt here.
That doesn’t mean it doesn’t sometimes happen, but at this point there’s no evidence that the Boring Company is really doing anything particularly novel at this point...
SpaceX was also not really novel. Their engine, construction method and most things were pretty standard and not very impressive.
I guess if we're being pedantic, he also didn't bootstrap Tesla.
He has a knack for attracting nice attention and generally is a great marketeer for his brands and himself as a brand.
He's also great at extracting government funds.
