Back when this was high tech, people were already thinking about artificial intelligence. One of the first attempts at what we would now call a “chatbot” was Eliza. Eliza was developed back in the 1960s and the first reference I could find was a paper written about the simulation and how it applied natural language to computer programming.
By today’s standards, Eliza is not very smart; it’s pretty easy to see that she analyzes the sentence structure looking for verbs and then creates questions based on the words after the verb. But for 1966 that was pretty hot stuff. In fact, Eliza was built on a then-prominent psychological method where the therapist provides as little feedback as possible. In that vein, she works remarkably well.
Hundreds, if not thousands, of nascent computer geeks fed Eliza’s code into the home computers of the 1970s and 1980s, either through cassette tapes or by typing code in from a book. When the program ran, the result was thrilling; these largely male hobbyists had come as close as possible to building a real girl!
