I would claim that the majority population of techies probably do desire to live in cities and hubs in which there are large communities of other techies, you're right. My point is just that there is also a sizable community of people who work in tech who also enjoy living outside the city, and can still enjoy a city lifestyle from time to time as well.

I often notice that this sizable community is brushed to the wayside because they aren't the in-crowd of city-based IT enthusiasts, with their regions being considered "flyover" and their opinions devalued. Yet still, in small towns, we do have Slack and hackerspaces and lots of professional development, just like the cities.
