I think it come down to intelligence augmenter is hard to separate from skill augmenter. Reading a chess book can make a beginner much better at the game, where following the instructions of a chess engine doesn't have any enduring impact on skill. Computer as orical such as with chess engines, or weather models isn’t actually improving intelligence any more than a truck is improving strength.

Word processor, email etc, can speed up how quickly an author gets stuff done, but they don't turn the average person into a good writer. You basically need to become an engineer before CAD tools let you design a state of the art car engine.
