The Evolution of Chatbots

One of the first and most famous early chatbots, Eliza, would not have passed the Turing test. She was programmed by Joseph Weitzenbaum in the mid-1960s. Psychotherapists were fascinated that several hundred patients an hour could be handled by a computer system. And indeed, cognitive behavioural therapy is now administered by chatbots, such as Wobot,. There's no pretense that they're human.
