It sounds like the author is projecting. The author may live like this (and I know many others that do) but quite a few still watch tv shows, still watch cable shows, still follow news programs, etc.
In 10-20 years, the author may be correct but, right now, the trend is not true although it might soon be.
Probably so. Lots of young adults don’t care about news at all. I think that is why the computer and Netflix stuff is so popular. No one wants to be exposed to anything unpleasant or bothersome. I imagine it will eventually just be movies and sports. For those that do want news, it will just end up being what they want to hear and agree with.
