Science Fiction
Science-fiction writers are no better than anyone else at predicting what is to come. The future, after all, is unknowable. Often people try to extrapolate a recent trend straight into the future, but society and technology rarely change at a constant rate. Other foretelling techniques are similarly doomed to failure. Science fiction, however, does recognize the value of prognosticating: it tends to reveal the preoccupations of the present.
