Yes, and I think this just shows how a 3d representation on 2d gives our brain the _illusion_ of 3d. This doesn't work for 4d, because our brain doesn't have an internal understanding of 4d objects.

I agree and I think it will never have. We can certainly speculate but ultimately it'd be like an animal with monochromatic vision trying to see colours.
