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 haven't written a whole lot of nonfiction, but what I have written leads me to believe that it's an entirely different muscle. The ongoing paradox is that sometimes it's harder to get to the emotional truth of something when you only have the facts at your disposal.

I think of this a lot in the terms of books. Of course there's a big to-do culturally about e-books versus print books, sales models. The paradigm has changed but my perspective on it is that there's not going to be another paradigm to alight on because everything will continue to evolve so quickly that our brains won't be able to keep up with it.

One of the great things about the Bible, one of the things I think keeps people coming back to it, is that it's nothing if not perpetually topical. You don't have to dig too deeply into today's paper to find slaves and masters, evil authorities.

All of which raises the question – your task, burden, privilege, call it what you like – a question which men and women, great and not-so of every color, creed and sexual persuasion have asked since they first had the language to do so, and probably before: Does Anything I Do Matter?

Most of my writing is an effort, one way or another, to figure something out about myself, and often when I read dialogue between my characters I recognize it as a discussion between two aspects of my own personality, aspects which are too often at odds.

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.
