I feel like the symbol of the 2020s is Chesterton's Fence[1], people chafing against restrictions and then having to reinvent them. I'm sure that some people are indeed fleeing California, and will then immediately start reinventing it.
Not that that's necessarily a bad thing. The reinvention could be like a clean-sheet reimplementation that's better than maintaining a smelly old code base. But that only works if you know all of the reason those code smells are there, and don't simply re-start the same process to recreate the same bugs.
