Fresh from the clogged tubes of teh intarwubs…
"I read too many SF books about future worlds that differ from our own in only one or two aspects. Otherwise they have the same sort of economics, faiths, politics, prejudices and so forth that we have now. In my own lifetime I have seen our world transform radically in many, if not all, aspects of life. I wondered if I could do a more realistic evolved society than the norm, and I set out to push our world a few decades into the future in my imagination. This is a hard job because everything affects everything else, and I had to do a lot of rewriting."
