With the advent of ELIZA, Joseph Weizenbaum's first psychotherapist chatbot, NLP took another major step with pattern-based substitution algorithms based on simple regular expressions.

My lecturers in compuational linguistics talked about #ELIZA in a different way. According to them, Weizenbaum's intention was to demonstrate how easily people can be tricked into believing that they are communicating with a sentient being.
To do so, he used a peculiarity of Rogerian psychotherapy: The therapist tends to mirror what the patient said.
So Weizenbaum's achievement with ELIZA was not a breakthrough in NLP but a warning to us.
It's timely to remember his warning as we see lots of people making false assumptions about imagined cognitive abilities of #LLM-driven chatbots just because they produce fluent text.

As you might read the longer text included in the slides, I don't disagree with you ;-) .And yes, the fatal effect that people are easily tricked to overestimate the machine's "intellectual" capacities is exactly what I am talking about to the students pointing towards today's popular LLM-based chatbots...
However, ELIZA was a first simple chatbot and thereby a milestone in rule-based NLP of that time (i.e. the 1960s)
@lysander07 Sometimes I forget that other people's toots are limited to 500 characters. Apologies!
Eliza war aber kein Therapie-ChatBot, sondern ein ChatBot, der eine einzelne Schule der Therapie persiflierte und mit dem Weizenbaum auf Technologiegläubigkeit hinweisen und davor warnen wollte. Er war entsetzt, dass Menschen diesen simplen Pattern-Matcher wie einen menschlichen Therapeuten behandelten.
