Famous "mother of all chatbot" programs by wikipedia:Joseph Weizenbaum. Eliza was in fact a generic engine for producing / conducting interactive dialogues. The "DOCTOR" script became the legendary example of a "Rogerian" psychologist employing mirroring technique to converse with its user as patient.
