Most other people don't have access to nearly the same levels of capital that would allow them to fail at multiple millions, now billions, of dollars investments. And of the few that do have that money they are generally fairly risk adverse to losing so much when they can get near guaranteed returns rather than making huge gambling risks. Especially when doubling your millions of dollars would mean basically nothing in terms of quality of life improvements.

I.e. Musk did it and they didn't. Musk gets the credit.
