Or Nvidia comes out of this damaged but not nearly as much as if they were glued to Jensen. "Superstar" CEOs that have complete control over a company are only benefits until they become enormous risks.

Reminded me to that Osborn scene at 2002 Spiderman.

There is no way that would have been possible. And as I saw another commenter mention, even if NVidia were founded much more recently when dual share structures became much more common, you rarely (or maybe never, I can't think of any cases) see that dual share structure in very capital intensive industries like hardware where you have to sink a ton of money into the enterprise before you even see any revenue. Software is a whole different ball game.

But Elon Musk has supermajority through dual-class shares in SpaceX which is obviously a capital-intensive business even more so than making GPUs.

You are correct, and I was wrong. I originally thought SpaceX was a bit of a special case because the board (pretty much Musk loyalists) gave Musk a ton of restricted stock right before the IPO, but the voting rights vested immediately. But the part I was wrong about is thinking that was just an IPO thing. All the many billions that SpaceX got pre-IPO was done with investors being fine having Musk alone having majority voting control.
