Your life has more blue in it than a James Cameron movie.

I wonder if kids growing up now are actually going to have that - if they're ever going to be able to unplug and have that ability to concentrate, or if it's just never going to happen for them. It's a little unnerving, frankly.

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

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.

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?

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.
