I am not your God. Or if I am, I'm no God you can seek out for deliverance or explanation. I'm the kind of God who would eat you without compunction if I were hungry.

The urge to move is natural and understandable. As will be the case throughout your life, no matter how long or brief, the choice is, in the end, yours. Simply bear in mind that most every choice will have consequences, and in this instance those consequences would likely be quite grave.

When you're a child - and my understanding of it is very basic - but when you're a very young child, the stimuli around you prompt your brain to form synapses. Once they're there, they're there, but if they don't form by a certain age, they're not going to.

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.

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.

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

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.
