Singularity theory is something that I do believe will come to pass, sooner or later, although whether or not in our lifetime I don't know, and I'm not sitting around waiting for my father to be resurrected. Readers probably have the impression from the book that I'm a lot more a of a techno kook than I actually am. It became a convenient fulcrum in the story, sort of a kaleidoscope through which to address religious and spiritual questions.

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 know well what faith really means to people in their daily lives, as there are many people in my family whose lives are permeated by their faith: it dictates the way they behave and sustains them in tough times, of which we've had too many lately.

On a micro level, if we're not terribly lucky, this sort of thing can happen to us quite frequently - the political becoming the personal in dramatic and irreparable ways. I remember the first time I went out into the desert, passing by all these mine fields and getting the history on them from my guide and realizing all these murderous mechanisms were real, were just sitting out there waiting for a victim, and some of them had been for sixty, seventy, eighty years.

If I had a nickel for every time someone told me apologetically "I don't read fiction," I wouldn't have to write fiction anymore. And I share that fascination with the truth. I'm not looking down my nose at it.

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?

You wish they understood, as you do, that there is no escape and never was, that from the moment two cells combined to become one they were doomed. You wish they understood that there is joy in this fact, greater joy and love in just this one last moment than they experienced in the entirety of their lives. Because even in this last moment there is still Everything, whole galaxies and eons, the sum total of every experience across time, shrunk to the head of a pin, theirs for the asking, right here, right now. And so anything, anything, anything is possible.
