We certainly have come a long way.
I agree that at times it can easily be taken for granted, but at the same time these progressions have of course been made based on growing needs and refinements.
Not everyone will need to take advantage of these progressions, but there are enough people/businesses/governments/universities etc. that do or that can benefit from it, and so they still benefit everyone as a whole.
It wouldn't surprise me if there are still plenty of places stuck with dialup in the US though, as their ISP situation seems to be a mess that keeps having money thrown at it but without much change actually taking place.
