Widespread gigabit is a recent development, and it's still expensive. Whatever technology takes advantage of it is a few years out. I had megabyte cable ~5 years before YouTube launched.

> gig internet is already widely available

I don't have it available and I live in an urban area. Hell, I don't even have a viable alternative to my cable company. There's a ton of bureaucracy around all of it.

Political nonsense aside, we rarely see the use for something when it first comes out. That includes really useful things. e.g. all of the super important inventions that were straight up accidents.

Sure, it could take years, but I can't imagine having faster communication between more people not having a huge effect.
