Rashida Jones

There's people who watch shows while they're preparing their dinners, and they don't want to focus, and they don't want to be challenged, and whatever. And then there's people who want to really sit down and get into a character in a world, and feel like they're expanding, or they have complex relationships, or whatever.

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.
