Machines Like Us

Chatterbots from MyCyberTwin can respond to questions about you when you're not online.

Historians of artificial intelligence never talk about AI's progress in the 1960s without a reference to Eliza, the first virtual personality. Eliza was a text-chat program written in 1966 by MIT AI expert Joseph Weizenbaum to parody a Rogerian psychotherapist, largely by turning every statement by the "patient" back into a question. If you tell Eliza "I am feeling blue today," it's apt to respond, "Do you enjoy feeling blue today?" To modern users, the pattern is obvious, and the illusion of talking to a real person drops away almost instantly. (See for yourself here or here.) Yet many people who used Eliza when the program was new were convinced, at least temporarily, that it was a real person.

Now there's a Web-based service that, in essence, lets you set up your own Eliza and train it to mimic your own personality. No one will be fooled into thinking it's you, but MyCyberTwin, launched earlier this month, does a decent job of acting as your stand-in or virtual public-relations agent when you're not reachable. If you embed your cybertwin in your blog, website, or MySpace profile, visitors can learn about you through an open-ended conversation. You can program your cybertwin with as much factual information and as much of your personality as you like. If you think visitors to your blog might ask "What are you doing Saturday night?", you can train it to respond "Going to see Harry Potter with friends. Why don't you join us?"
