I am pretty sure wireless is really going to change this in the next few years. Most of those locations probably already have LTE coverage and many times its better than the wired tech in the area.

Everyone is just waiting for a good unlimited plan and many will just move over to hotspots / LTE routers. It has the benefit of going with you when you travel or move and the carrier like it because last mile is so expensive to upgrade.

I know a lot of people working remotely in RV's moving around the country and it's only possible because of good wireless coverage that's getting better very fast.

I think with more remote work and better wireless coverage you could see floodgate open of tech workers moving to rural areas, I know I want to.
