So, in the early days of computing, Alan Turing, one of the most influential Computer Scientists of early computers, proposed the "Turing Test" for AI systems. Basically, it said that, if you are interacting with it and you can't tell whether you're interacting with a computer or a human, that's true "Artificial Intelligence". The problem was, it was beaten pretty quickly by a program called "
Eliza", named after Eliza Dolittle from
My Fair Lady and Pygmalion because they taught it to talk.
Basically, Eliza assumed the limited social context of a Rogerian psychologist and attempted to imitate the psychologist. You know, you say "I hate books" and they/it responds "Why do you hate books?". Well, if you look, it didn't even change the input very much, it just kicked what you said back to you (think the Lucy Liubot episode of Futurama (3.15)). Eliza licked the Turing Test hollow, but it was the stupidest program you can imagine. A few hundred lines of code and no actual knowledge of psychology and barely any of grammar. Eliza is a very famous program, not because it's AI, but because it showed the Turing Test wasn't much good, not because computers are smart, but because humans can be pretty dumb. It turns out that, if the social forms are rigid enough, it's tough to tell the difference between a smart computer and a dull human. In fact, Eliza was so famous, when I first learned about IMbots (like the
WSJ or
Moviefone bots), my plan to build one was to filch somebody's Eliza engine and hook it up to an AIM account.
Well,
somebody beat me to the punch (HT
Instapundit), except they didn't mimic a Rogerian scientist; they mimicked members of a dating chat room and used it to steal personal information. The AI researcher in me (a former life, as computers go; 5 or 6 years at least) is curious to know if the social rules of flirting in a dating chat room (which, given the limitations of text, I assume are pretty rigid) are more or less rigid than a Rogerian psychologist. Did they just change the rules in the ruleset, or did they have to do any actual work?
Then I realized that I don't really care enough to investigate. It's funny enough as it is.
