If you call, spraying bullsh!t around, finding bold new ways to line his pockets with other people's money, sponging off US government's money and technology, "earning", then you;re right.
With respect to Tesla, it lost money for years. Despite that, the stock radically increased in value. When he ran out of US funding and tax breaks, he built a factory in China.
With respect to his battery, "gigafactory", that's was, in part or in whole, funded by Panasonic.
With respect to Space X, he.quite frankly, fell heir to huge amounts of NASA technology. The primary reason for that is, NASA was forced to take NASA, of the US budget.
As far as his "breakthrough, land themselves, recoverable boosters", that's his engineering staff's "triumph", not his.
The joke here is,that could have always been done, save for the fact that to save fuel for landing, you have to sacrifice payload capacity. Oh, BTW, the computers on the moon landers, were barely comparable to an Atari 800. They're much, much, better now. Do you think they helped? Because Musk didn't "invent them" either
As for Twitter, that's a deal he ran his yap about, tried to wriggle his way out of by bashing the platform, on that very same platform, found out he couldn't, then "magnanimously" offered to go through with it.
You, and many others here seem to think he's, "playing with his own money". He's not. He had to do what everybody else does, and beg for money to finance the deal.
Which goes back to what he's really the "GOAT" at, and that's taking money out of other people's pockets, and putting it into his own. In this instance though, he found he couldn't bullsh!t his way out of it, without stepping in the big pile of crap that he himself laid.
If we go back to this lawsuit, I actually think he's right, assuming that the 60 day severance was actually dispersed. As to the semantic point that, "60 days severance is equivalent to 60 days notice", that is for the courts to finally decide.
