Re: This is where we are now
"I think it's fair to say that if we had already wired up the globe with fiber internet,"
In the US there is loads of dark fiber just waiting to be used. Fantastic amounts of money was spent to criss-cross the country and engineers figured out how to multiply the information going along each fiber to the point where much of what was installed became redundant.
Places where there is enough density to support wired high speed internet, it's available. In the out of the way places, there are still options including satellite. The big swaths of unserved land is in areas where very few people can afford it.
