“I am naked as I type this. I was naked writing the whole damn book.”
Peter Watts, Echopraxia

Scott Kaelen
“Ah, Drilos. I wanted someone to talk to, but I never counted on a conversation quite so hilarious. Not only are you saying I’m the multiverse, but also that I’m becoming something devoid of existence? Ridiculous. Right now I’m just a disembodied consciousness, but as long as I exist in a void then the void won’t be a void. Right now I consist of energy rather than matter; it’s just nature’s way of compensating for the random space-time shifts of a being it apparently doesn’t want to die. Fission, fusion – I don’t make up the laws. The where and when of me are easy questions to answer. What am I? That’s a bit more difficult, but ultimately I was born a human, and nothing can change that. The how and the why of me – now there are two questions that are impossible to answer.”
Scott Kaelen, The Hyperverse Accord
