A Leap from Artificial to Intelligence

I am astonished that people who know what computers can do, and, especially, how they do it, still think we (humankind) will ever create a rational being, much less that the day is near. A program that can play winning chess or Go is not one. We all knew it would happen sooner or later. We are talking about a large but finite set of paths through a well-defined set. But such things are the work of engineers, not of the computer or its programs.
