That trope is really annoying. California has become more liberal because conservatives have left, so putting all of them into the same basket is dumb. Though I guess conservative Californians aren’t moving to ultra liberal cities like Austin for ideological reasons.
Not sure. There aren’t that many conservative software developers, and those that are are more likely to wind up in Provo or Boise. On the other hand, there are lots of conservative Californians outside of the Bay Area and outside of tech who have left the state, they are more likely to have wound up in Texas.
Let’s hope the Bay Area can lose a million or two people to bring some sanity back to traffic and housing prices.
