About Marines beating a DARPA robot by hiding under a box, and AI lacking common sense.

I would put it in terms of continuity of state rather than continuity of function: we use our current ML models to approximate the real world by assuming that state is irrelevant. However in reality, objects exist continuously and failure to capture ("understand") that fact breaks the model in unpredictable ways. For example, if you show a three-year old a movie of a marine crawling under a cardboard box, and when the marine is fully hidden ask where the marine is, you will likely get a correct answer. That is because real intelligence has a natural understanding of the continuity of state (of existence). AI has only just started to understand "object", but I doubt it has a correct grasp of "state", let alone understands time continuity.

An AI shown a video of a marine crawling under a cardboard box correctly says where the hidden marine is.
