A ten-year forecast

You met Herbert Simon's forecast in Module 2.

In 1957, he predicted that a computer would become the world chess champion within ten years. He had just watched an early program prove mathematical theorems, something that had looked like human reasoning.

The prediction was late, but not absurd. Deep Blue eventually defeated the reigning champion in 1997.

This chapter asks why broad intelligence seemed so close from where Simon stood. Why did one working program make the remaining distance look so short?
