A world without books

Still getting used to a generation of animation students who don't rely on books. While there is a huge amount of material and tutorials online, I wonder how they "index" it all in their minds.

And I don't just mean bookmarking websites. Growing up with books made me learn how to "index" which specific material was in which particular book. My point is, what will they do when they are in a situation where they might be cut off from the web? Of course that might be in the midst of a huge natural disaster. Don't mean to be so gloomy, but what will the human race become?

 "Books? Yes, we have books."
