When I start writing a new imaginary future, I have no idea what it is. The characters arrive first. They help me figure out where they are living and I get to fill in the gaps with that and where we are. So when I get to the end of the process of composition, if I feel that I have really done my job, I have no idea what I've got - and I then spend essentially the rest of my life figuring out what it might mean.
