Nobody really knows when the body dies. After brain death, and then organ failure, and all the electricity's gone, a rotting corpse still feeds the world, mother's diesel for the biological engine of life. Who knows where the internet will go, or for how long, or in what strange aeons it will return? Who can say if ours was even the first?
