gollark: I think a useful component of AGI would be being able to efficiently offload subtasks to specialised algorithms instead of just doing them inefficiently in neural networks, but I have no idea if this is very practical or anyone's doing it.
gollark: There are tons of non-learning algorithms which are good for logical reasoning. The fuzzier stuff which humans do easily seems to be what's harder to implement.
gollark: Just encode data in otherwise irrelevant details of the text which tokenisers remove/ignore.
gollark: It should randomly use a generated goose or actual goose and see how often people can tell the difference.
gollark: Someone should make the command more efficient by checking the goose's direction for you, automatically.
