Am I a technocrat? Im just a guy who went down to the bookstore and bought a couple of textbooks on TCP/IP, which is the underlying protocol of the Internet, and read them. And then I signed on to a computer, which anyone can do nowadays, and I messed around with it for a few years, and now I know all about it. Does that make me a technocrat?

I'm strictly a one-project-at-a-time kind of guy. If I came up with a compelling idea for a different book while working on a project, I'd probably abandon the first project and go with the new idea.

An old market had stood there until I'd been about six years old, when the authorities had renamed it the Olde Market, destroyed it, and built a new market devoted to selling T-shirts and other objects with pictures of the old market. Meanwhile, the people who had operated the little stalls in the old market had gone elsewhere and set up a thing on the edge of town that was now called the New Market even though it was actually the old market.

Even the best of us have certain psychological mechanisms that can suddenly kick in and turn us into monsters. That to me is the basic message of events like the rise of Nazism, the Salem witch trials, and so on: not that bad people do bad things, but that good people do bad things. It's distressingly easy for those mechanisms to be triggered, either consciously by demagogues, or naively by people who think they're trying to do the right thing. Which is why I think it's more akin to tic-tac-toe.

'It’s, like, one of them drug dealer boats,' Vic says, looking through his magic sight. 'Five guys on it. Headed our way.' He fires another round. 'Correction. Four guys on it.' Boom. 'Correction, they’re not headed our way anymore.' Boom. A fireball erupts from the ocean two hundred feet away. 'Correction. No boat.'

How could your cover be blown in Canada? Why even bother going dark there? How could you tell?

Early on, I settled on the first-person strategy as a way to deal with exposition and world-description issues. As long as the book is, it could have been far longer had I gone with an omniscient third-person narrator, or multiple point-of-view characters, since either of those would have enabled me to impart much more detailed information about the history and geography of the world.
