I mean, just look at California's history. If people were willing to upend their lives since the 1800s to move their families to the other side of the country on vague things like the promise of striking it rich somehow, those people probably had distinct personalities. Every one of California's strongest industries have been because people escaped where they were to go strike it rich (in money or fame).

Wine, Movies, Farming, Banking, Education, Tech.

California is just a state with a long history with a weird mixture of entrepreneurs you won't find elsewhere.
