I am living in SF now and this confirms a very clear pattern that I have seen emerging, particularly of tech workers. I would say that >50% of the people I know who were living in the city have left, or are in the process of leaving. Some examples (there are countless):
1) All three of the roommates that I had are choosing to leave either permanently or temporarily.
2) A friend who works for google who is going on a 6 month road trip in a camper van
3) A friend who is moving to Santa Cruz just to be closer to surf while we are remote
4) A friend who moved home to Australia because of how the US is handling the virus.
5) A friend who is going month to month in different cities, staying in Airbnbs, and still paying less for housing then his one bedroom in the bay area
6) A friend who moved to Austin to live with her sister
What I am seeing here is very clear also. The SIP order has removed many of the greatest parts of SF, the food, the bars, the culture, the density to be able to go anywhere and see your friends easily, and whats left are many of the problems that the city has, trash, homelessness, and exorbitant housing prices.
