I guess the remaining medium which you can't just numb your body out to is the written word? Books (esp. classics) are still just as intriguing and engrossing as they were when they came out. You can't _really_ binge a book like a TV show. Books don't have live concerts where the point is entirely other than the enjoyment of the content. Books benefit from all the technological advancements of today (e-readers, e-ink, digital copies, etc) without having to become vapid background scenery as a result.
And of course, books make way way way less money than movies and music as a result. Not sure what I've proven here, but just the thoughts I had while reading this article.
