Science fiction is not predictive; it is descriptive.... Prediction is the business of prophets, clairvoyants, and futurologists. It is not the business of novelists. A novelist's business is lying.... Open your eyes; listen, listen. That is what the novelists say. But they don't tell you what you will see and hear. All they can tell you is what they have seen and heard, in their time in this world, a third of it spent in sleep and dreaming, another third of it spent in telling lies. —Ursula K. Le Guin
