intelligence/understanding is when one can postulate/predict/calculate/presume something correctly, from concepts about it, without that thing (or similar) ever been in the training/past (or even ever-known).

Yeah, not all humans do it. It's too energy expensive, biological efficiency wins.

As of ML.. Maybe next time, when someone figures out how to combine deductive with inductive, in zillion small steps, with falsifying built-in.. (instead of confronting them 100% one against 100% the other)
