Verizon (and all the others) throttle between 20 and 30 gigs at peak usage times. So if you're a light TV watcher it can work as your internet connection. I have a work colleague who does this -- he just puts his Verizon phone in hotspot mode. And he telecommutes from home, writing software, so he needs a rock solid connection.
It's not quite a Moore's Law pace, but bandwidth gets cheaper every year, wired and wireless. It was just 5-6 years ago AT&T and Verizon phased out their unlimited plans (angering lots of customers) because they didn't think they had enough bandwidth to support them even at 3G speed. Now everybody's got more LTE bandwidth than they know what to do with, which is why the unlimited plans (and yes, throttled at 100 gigs or whatever) have been reintroduced and are so cheap. If you're only an occasional watcher of TV, you really can use it as your home internet.
Just 7-8 years ago I was getting a solid 15 megabit Fios connection and that seemed awesome. Now for pretty close to the same price Fios offers 960 megabits in certain markets. Five years ago I was getting about a 20 megabit connection from Comcast, then it went to 25, then 50, then 100. 100 megabit is basically Comcast's most common internet these days. As Comcast rolls out Docsis 3.1, their sweet spot will probably be 200 megabit.
5G is at least 5 years away but some markets will see experiments sooner. But that will be revolutionary because there will be fewer towers broadcasting at much greater range, and the volume of bandwidth will be vast by today's standards. Probably 5G will be viable for home internet. Plus there are all kinds of hybrid systems being tried in urban areas like Netblazr -- wired network backbones that deliver the last quarter mile wirelessly to rooftop antennas. Much cheaper than maintaining cable to everybody's house.
