I remember Detroit feeling really unsafe, feeling scared a lot. Our house was broken into, our car was stolen, we had to get a watchdog, we would get beat up in the street, I had my bike stolen. There was just a lot of real anarchy on the streets and sidewalks.

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.
