ELIZA

ELIZA is an automated psychoanalysis program based on the psychoanalytic principle of repeating what the patient says and drawing introspection out the patient without adding content from the analyst.

Weizenbaum invented ELIZA more or less as an intellectual exercise to show that it could be done. He was disturbed to see it used in serious psychological settings. He believed a computer program shouldn't be used as a substitute for a human function that requires interpersonal respect, understanding, and love. Thus, he rejected its use, not because it was technically flawed, but on ethical grounds.
