There is a lot of talk in publishing these days that we need to become more like the Internet: We need to make books for short attention spans with bells and whistles - books, in short, that are as much like 'Angry Birds' as possible. But I think that's a terrible idea.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
