ELIZA was one of the first (and longest) BASIC programs I typed into my then brand-new 16K Apple II in 1979. Originally created at MIT by Joseph Weizenbaum in 1966, this pioneering natural-language-processing simulation of a Rogerian psychotherapist impressed my family and friends every bit as much as Siri does now. I was curious to see how they would get along.
Here is a transcript of their first encounter. Despite their 45-year age difference and two-million-fold disparity in RAM, I thought they understood each other remarkably well.
