"Meet your descendants. They don't know what it's like to be involuntarily lost, don't understand what we mean by the word "privacy", and will have access (sooner or later) to a historical representation of our species that defies understanding. They live in a world where history has a sharply-drawn start line, and everything they individually do or say will sooner or later be visible to everyone who comes after them, forever. They are incredibly alien to us." (Charlie's Diary)
