@Paradox The last part is what's interesting about this: If I think about it in terms of AI or cognitive algorithms, he had ridiculously little training data and still his brain implemented an algorithm to extremely efficiently & effortlessly do math at an extremely high level.
Maybe math is just algorithmically shallower than we usually think?
@niplav Nah, I don't think that's it. We're still the ones coming up with the algorithms. Math is pretty much just coming up with a bunch of rules and trying to build things within those rules. Sometimes you have to use different rules for different things, like Euclidean and non-Euclidean geometry.
I don't know anything specific about Ramanujan's math, although I have been reading Matt Parker's book about math and he talked about Ramanujan for a bit. It might be that Ram used a different set of rules from the norm, and I think the symbols were different too, although that probably wouldn't have helped him make anything groundbreaking, just obscured the data from others unintentionally.
