Yes, it does. There are tons of things that we don't know how to get e.g. robots to do in the physical world and it seems that animals have a library of heuristics that let them do them cheaply and accurately. We totally want to be able to learn those heuristics of search for them and find them somehow. And that's why my point was that we don't know how to come up with heuristics: because we currently don't. Edit: if you mean that we can probabilistic-recall all those heuristics, that's not right. Because such heuristics are tacit knowledge that is very difficult, maybe even impossible, to articulate with enough accuracy to reproduce in a computer. We certainly can't get LLMs to learn them from the web because the web doesn't have text that explains e.g. how to control your muscles to climb a tree.
