The real issue is humanity is pumping out more and more content each year, to the point where it would take several lifetimes to consume it all. This means there is no big central pillar anymore, simply everyone is into just their own stuff. Everyone's tastes are so unique that other than some cursory similarities in taste most people still have wildly different preferences. It was always this way, but now with near endless content of books, blogs, websites, news, tv shows, movies, music, and video games people have more choice than ever and each choice means they are missing more and more other content by making that choice.

Its so overwhelming its making some people check out of media consumption nearly entirely.
