I agree that there is a trend away from California, doubt it is related to NIMBY-ism, governments. When Hewlett & Packard or Steve & Steve kicked off their businesses in the Bay Area it wasn't because government was friendly or NIMBY-ism was lacking.

Now it's simply too damn expensive to live in the Bay Area, too expensive therefore to hire.

That's the cost of success and why the 3 to 4 (5 to 7?) decade trend.

Austin will become too expensive and everyone will head to North Carolina (or wherever) in a few decades....
