A lot of the despair we feel watching the news every day flows from our sense of helplessness, and as a fiction writer you get to control things, if only on the page. You get to run the show. You can right wrongs, bring departed loved ones back to life, even take vengeance on God, if that's your thing.

Oscar Pistorius is now infamous for reasons that I think everybody knows about, but when I hit on his story and put it in the book, what I found fascinating was a description, from one of the scientists who helped Pistorius, of what the Paralympics will become. Because they don't place any restriction on enhancements for athletes, in the very near future the Paralympics will bear a closer resemblance to NASCAR than to the traditional Olympics. There will be a human-machine melding that will result in crazy feats of athleticism.

I think that anyone who grew up reading and being taught the Bible, as I did, can't help but have their prose shaped by it later in life. I still have deep, almost primal responses to the language of scripture, and I think that comes through in all my writing.

We're not cognitively equipped to deal with it. And it's becoming a problem, frankly. It's part of the reason why I quit Facebook. We all hear these things and read reports about how our attention spans are shrinking. It makes me wonder about the generation growing up now, how it will affect their brain development.

As an atheist and lapsed Catholic, I feel the absence of faith in my own life quite acutely.

People have invoked the ghost of Hemingway quite a few times in writing about the book. I could get into sticky territory here if I let myself go on about this subject. The more I hear it, the more it rankles, frankly.

Some people believe that everyone will experience judgment day. But it's my understanding that the Judgment Day or Rapture that I'm going to experience, as a nonbeliever, is not going to be the good part. That's the essential difference between the Singularity and what we're usually told about the fate of our eternal souls.
