I know it's just one anecdote, but a Subway employee in SOMA once asked me if I knew anyone that would hire him as a DBA. The feeling in SF is that the tech world is inescapable, which some people seem to like.

I moved to SF two years ago. Since then I've had a discussion with the cashier at Taco Bell about the differences in the way browsers render on different mobile OS's. Had a discussion with a banker that learned Ruby to help with some of his reporting...

Tech is everywhere here.

That's a bit pedantic. It's pretty clear that the point the author is trying to make is that relative to other cities, a ton of people work in finance or startups so you will encounter a lot more of them. Not that every single person in the city falls into those two categories.

This whole article is written very clearly with a very specific audience in mind. "You will be come an early adopter!" Well, maybe. I guess if you work in tech and know people who work in tech, yes. But as you noted, there are plenty of people who don't.

I think the implication from the original was that you don't really meet the other people, in that sure, you encounter them, but they somehow don't matter or are less interesting.

I don't think the poster meant that, so I wanted to call it out to encourage us techies to see that we are part of a larger culture and context.

We depend on a hell of a lot of people, and a lot of infrastructure that's not just for us, but keeps the entire city going.
