“Science fiction is not predictive; it is descriptive.
Predictions are uttered by prophets (free of charge), by clairvoyants (who usually charge a fee, and are therefore more honored in their day than prophets), and by futurologists (salaried). Predicition is the business of prophets, clairvoyants, and futurologists. It is not the business of novelists. A novelist's business is lying.”
