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.

I'm definitely excited by big ideas, both in what I write and what I read. Most days, reality is so mind-numbingly dull that I don't understand why someone would write strictly realistic stories, given the almost limitless freedom fiction provides. I don't see the point of making believe if you're not going to actually make believe: hang your ass out in the wind, push at every boundary, make almost unreasonable demands on your reader's willingness to suspend disbelief. This is dangerous, and prone to failure, but that's part of what makes it fun.

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.

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.

I tend toward the pessimistic end of the spectrum, and unfortunately there's little in human history to convince me that pessimism is unwarranted.

Singularity is seen as an event horizon. There's everything that comes before it and everything that comes after it and never the twain shall meet, in much the same way that Judeo-Christian theology presents its notion of the afterlife - there's a very clear and impermeable demarcation there.
