Note, you’d need to train such a model on data teaching it about the relationship of every number to every other number when run through every function. Yes, infinite synthetic data, but you’re just memorising stiff you can already generate
Or build a model that has "peripherals". Oh, I'm being asked to do math. Let's put it in my calculator app. Everything doesn't have to be in one uniform network.
Evidently the brain works that way: the cortex is built on top of older components, so it doesn't have to figure out basic metabolism the same way it has to learn to identify people.
