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.

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.

And knowing that the only alternative to your grief is the nothingness that’s fast approaching, you try to embrace your own sorrow, to be open and empty and let it all pass through you. This is the key, you have learned – to relinquish control, to relinquish the desire for control. Even in this late drama, to try to control is to go mad. And so you do your best to let it all go.

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 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.

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

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.
