The intelligent computer was a hot topic in the sixties and seventies. After the most optimistic prophets had lived to see that their “in twenty-five years” predictions of an intelligent computer had failed to appear, the few remaining are cleverly dating their forecasts several hundred years into the future. In addition there is also a change of content in their predictions of computer intelligence. Many have now moderated their statements, now mentioning “applications that would have needed intelligence if humans were doing the job.” But that is something quite different. The Vikings, for example, navigated by using the sun, moon, stars, and wind directions. Even bird flight and floating seaweed may have aided an intelligent or creative navigator. Today, we also use stars for navigating, but artificial stars, satellites, which send a radio beacon that is used by any GPS system to pinpoint the position on the surface of the earth with an accuracy of a few meters. It does a better navigating job than the Vikings just by computing a simple function, but no intelligence is needed.
