Between NIMBY antics with housing development and absurd levels of gov overreach in situations like this, SF is going to end up cannibalizing its tech industry.
So many cities would kill to be the center of such a fast growing and high paying industry, and they're squandering it because their old guard is a bunch of gate-keeping snobs.
Oh well. NYC, LA, Austin, and other cities will gladly grab the fruits of tech talent.
