Sort of like the manifold hypothesis in deep learning.

Huh?
As you increase the dimensionality of a sphere, an ever-increasing proportion of the sphere is within epsilon of the surface.
This 3Blue1Brown video addresses enough related stuff that the rest should become reasonably comprehensible: https://www.youtube.com/watch?v=zwAD6dRSVyI This particular result is tossed in as a side note around 23:25, so it's not addressed directly, but it'll help.
I feel like this would have to be true in a very high dimensional space, since an infinite dimensional orange is all skin.

This sounds really fun, could you try explaining a bit more about it?
Thanks for sharing.
