  1. 1966ELIZA — The First Conversational ProgramJoseph Weizenbaum at MIT built ELIZA, a natural-language conversation program. Its most famous script, 'DOCTOR', imitated a Rogerian psychotherapist by reflecting user input back as questions through simple pattern-matching. Many subjects in early sessions reported feeling that the machine 'understood' them—an effect Weizenbaum found unsettling enough that he later wrote *Computer Power and Human Reason* (1976) in part to caution against it.
