It really depends on the individual. I barely watch any TV and have been like this for the 30+ years that I’ve been old enough to own a display. For a while, I did go fully in with media centres. Even running XBMC on an original Xbox. But I honestly just don’t really care for video content all that much regardless of how it’s delivered.

But I also know a hell of a lot of people who still massively prefer watching content the traditional way. As in, not just TV shows, but on a TV too. And I have no more right to tell them how to consume video content as they do to tell me how I should consume the stuff I want to read.

Lol, your position is, don't watch tv, just watch YouTube. That's not really a radical shift.

Fine if it works for you, but TV has plenty of things going for it... big screens, watch from 10 ft away on a couch, watch with other people, regular schedule (i.e. Jeopardy on the same time every day), live sports, local news, shows with generally high production values. But probably most importantly, passivity - yes that is a feature.
