All my life I've encountered people who were obsessed with one particular class of object or experience, who were constantly pursuing that thing. Since I was a little kid, I hadn't afforded myself the opportunity, I guess, to have a hobby.

I'm very primitive in terms of economics. The kind of new business in which stock gets more valuable because the company grows, but there must be limits to growth. But if publishing is expanding to fill that retail space, it seems like there may be a necessary and unpleasant correction waiting down the road. How many books to people WANT?

Dreaming in public is an important part of our job description, as science writers, but there are bad dreams as well as good dreams. We're dreamers, you see, but we're also realists, of a sort.

Part of the core of my system, is a way of trying to give the characters more control. If I'm practicing making up what the characters will do, it's never good. In fact, when I catch myself doing that, I try to get rid of that section, and try and let them start making the decisions.

Sometimes, I feel like a time traveller, cause the only way that we can really travel in time is just to get older.

Maybe I've been a small part of the democratisation of celebrity, because I've been fascinated by it, and when it started to happen to me to the very limited extent that it happens to writers in North America, I was exposed to people who had the disease of celebrity. People who had raging, raging, life-threatening celebrity, people who would be in danger if they were left alone on the street without their minders. It's a great anthropological privilege to be there.

You know what your trouble is? You're the kind who always reads the handbook. Anything people build, any kind of technology, it's going to have some specific purpose. It's for doing something that somebody already understands. But if it's new technology, it'll open areas nobody's ever thought of before. You read the manual, man, and you won't play around with it, not the same way. And you get all funny when somebody else uses it to do something you never thought of.
