Im near a major city in georgia and at&t is the only provider of my town i am lucky I live 1000 feet from the exchange and can get 25/3 alot of people here stuck on 6/1 or 3/.5..........but I pay as much or more for 25/3 than people 10 miles away pay for cable and fiber 50/50 or 100/100.
The problem is ...most of the US still has shit broadband...I live right next to a major city and I'm stuck with att dsl. Many more are far worse on sat or data limited cell hotspots.
The conversion cost is to high. Solar panels are 20ish percent efficient. Converting to electricity and then to laser to hit a earth panel back into electricity....common now. Your losing all your power in transmission and conversion.
The thing is they are trying to install the fiber on the cheap......Google has given up on specific areas in the cities they serve when it gets to an area they have to invest in real work to install the fiber. They've done it in every city.
