With 5G, I think there's even less motivation for ISPs to provide fiber to those out of range. To the point where they'll just jack up the installation prices until no-one bothers them anymore.

At least that's the feeling I'm getting now. A friend of mine recently moved into a new building, which isn't too far from a fiber central. It's also out in the suburbs, so no extensive infrastructure like you'd find in the middle of a city...well, he requested a quote, and the company said - "hey, it'll cost you around $20k for [short stretch], but we're also offering wireless broadband for only [2-3 times the price of fiber, and 1/5th the speed)"
