There are, however, atypical linguistic outputs that are much easier to simulate. An early, eerily real-sounding program was Weizenbaum’s ELIZA, which simulated a Rogerian psychotherapist. (Rogerians take a passive approach, which mostly involves taking what the patient has just said, and turning it into a question.) Another domain of discourse which seems ripe for simulation is professional sports-talk, which seems to consist largely in repeating the same clichés over and over, with 20/20 hindsight.
