Historical contribution
What Weizenbaum contributed
Joseph Weizenbaum's ELIZA, developed in the 1960s, used pattern matching and scripted transformations to sustain text dialogue. Its DOCTOR script became famous not because it understood psychotherapy, but because users often supplied meaning and empathy to a responsive textual form. Weizenbaum later used the experience to criticise misplaced confidence in computerised judgment.
