I hadn't heard about that but it sounds like what I'm talking about. With their ever expanding training corpus Google's net will eventually learn that dumbbells and arms are separate entities, but it will never deduce that on its own. And if it did it would not be able to generalize that to the fact that wedding rings and fingers are different (I hypothesize). Basically there is a whole other component of "intelligence" that feels absent from neural nets, which is why visions of AI lording over humanity don't exactly keep me up at night. (Autonomous weapons otoh...)
