ELIZA — the illusion of intelligence.

In 1965, a professor at the Massachusetts Institute of Technology built a machine that listened. Joseph Weizenbaum's ELIZA could not think. It could not understand. But it could reflect language back so fluently that people began to trust it, to confide in it as though it were alive. Weizenbaum called this the ELIZA effect: the distance between fluency and capability, and the cost of confusing the two.
