Do you know the anecdote about Feynman and John Tukey doing a mental counting task and the one being able to talk while he's doing it and the other not, and then the reveal is they are using a completely different mental representation:

worth a read, to me it kinda indicates that different abilities can be enabled by differences in how to mentally represent something. but yeah its debatable how much of difference in ability comes from/with a difference in experience but I my gut feeling is a lot more than you'd think. feels really hard to prove it as we only know what it's like to be us.
