Even ignoring the posts that just straight-up assume all tech workers (or at least all the ones worth considering) are in Silicon Valley, I've seen so many posts that assume, in various ways, that tech workers live in cities. Or even that basically everyone lives in cities.
From people talking about self-driving cars ignoring that rural roads (including gravel and dirt roads) exist, or that roads exist that might not get plowed/sanded immediately after snowfall, to people talking about employment and compensation just assuming that any tech worker can instantly find a new job paying as much as or more than their previous job if anything goes wrong, to people talking about nutrition, health, and food assuming that everyone has access to a wide variety of great supermarkets and specialty stores...
The bias is real, and it's so deeply disappointing a lot of the time.
Even worse are the people who appear to genuinely believe that we would be better off if no one lived outside of cities. They never seem to have much answer to questions like, "Then who's going to grow the food?" beyond handwaves.
