"Certainly it's great to be able to talk to your friends about something. They might mention a film, and you can find all about it, and you don't have to wait months until you can find a book that might cover the subject and keep it in your head. You can have that kind of immediacy. But there's also something about it, where all the knowledge seems kind of fleeting. All the stuff I learn about in that way, I can be interested in for a day and then it's gone."
