Marvin Minsky, MIT professor and AI’s founding father, says today’s artificial-intelligence methods are fine for gluing together two or a few knowledge domains but still miss the “big” AI problem. He says the missing element is something so big that we can’t see it: common sense.

In his forthcoming book, The Emotion Machine, Minsky shares his accumulated knowledge on how people make use of common sense in the context of discovering that missing cognitive glue.
