That means AI is not capable of producing meaningful _new_ content like discovering new mathematical theorems, because AI does not understand maths, whereas humans can come up with something meaningful based on _understanding_ of the content they have learned from.
This is why when you ask e.g. ChatGPT about something it has not been trained, it can only come up with garbage, whereas a human would likely be able to provide meaningful answer based on looking at the same training data, if that makes sense.
