It absolutely is hardly any training for the types of problems humans have solved. Ramanujan did not need to consume the entire corpus of mathematics or even had much formal education whatsoever. He did so, again, on very few calories compared to pre-trained AI models. I am not claiming learning how to pick up a rock does not help you in any way to understand continued fractions but it is pretty unreasonably to compare an AI as has been demonstrated as being anywhere near the same sort of thing.
