How are you going to watch HD Netflix? Let alone 4K. Forget about it.
We won't and this is by design. Right now, if Americans want video entertainment, we mostly turn to cable TV companies. These companies have monopolies in their areas. Like a group of rival mobs, they've carved up the territory so that they don't compete with each other. They also have bribed... I mean lobbied politicians to pass laws to benefit themselves (the cable TV companies) at the local, state, and national level.
Now, with this level of control, the cable companies have enjoyed an almost unimpeded ability to charge whatever they decide and to offer services however they like. If you didn't like this, you had virtually nobody to go to. You could get TV from a satellite TV provider, but Internet was likely just the cable company or the phone company and the latter was increasingly going the high-priced mobile route.
Enter the Internet and high speed access. Now, consumers started realizing they don't need the high priced cable service. They just need a fast Internet connection. The cable companies are scared (though they won't admit it publicly - can't spook the shareholders) so they are trying to keep speeds slow, institute caps "to manage network traffic", and take other measures (such as messing with connections to Netflix) to minimize how many customers flee to Internet video solutions.
So not being able to watch HD Netflix or 4K? That's a cable company feature, not a bug.
