I definitely think it’s interesting that it’s possible for N-D-substrate-computations to imagine / intuit N+1-D, but yeah, I feel like that’s mostly a given because we have the concept of N+1-D in the first place.
There are different levels of “imagine / intuit” though. Some people have particularly good or bad intuition for the 3D space we live in. I took your claim to be something like “the average brain could intuit 4D just as well as 3D, maybe requiring slight modification”. I think the modifications to reach true parity would be pretty extensive, because of how much 3D-specific architecture (as opposed to weights) human brains have. I do agree the modifications are theoretically possible, but the modifications to give a fruit fly human-level cognition are also theoretically possible with arbitrary modification.
