20% work in tech? I think that’s gone up quite a bit since I last spent a lot of time there in 2015. I would see these articles from time to time and think, people are getting the wrong idea if they haven’t been there, when I think of SF I think of middle aged Chinese people and alleycat bike races and music venues and book stores and drug dealing and gays, though tech bros are also present (and overlapping). But damn, 20%, that’s a lot bigger than finance bros, maybe tech really is ruining the city. Shoot.

I think that’s 20% of the workforce not the population overall. That’s still a large number but its not the whole city. Also nobody is ruining the city, SF is doing just fine these days.

I mean, the author just pulled that 20% number out of his ass. Not saying it's wrong or right, but... c'mon. Let's take all of this with a big helping of salt.
