The comparison is good. Humans are also stacked in volumes and we still measure population density over a surface because the third dimension is less significant in this context.

I got the answer from the AI I was looking for & it makes sense. You can try to map the volumetric density to areal density but the mapping is not canonical so it doesn't say anything about the physical reality of actual transistor density since the reality is that it is a volumetric measure that gets fudged for marketing purposes. 3D volume for chips is going to keep increasing so they will eventually transition to measuring density over volume instead of area.
