“Have you thought about what it means to be a god?" asked the man. He had a beard and a baseball cap. "It means you give up your mortal existence to become a meme: something that lives forever in people's minds, like the tune of a nursery rhyme. It means that everyone gets to re-create you in their own minds. You barely have your own identity any more. Instead, you're a thousand aspects of what people need you to be. And everyone wants something different from you. Nothing is fixed, nothing is stable.”
