Interesting! Gauging from the original Reddit post, it seems that people exist on a spectrum regarding this for whatever reason.

This could explain a lot about why some people learn certain stuff faster than others. For example, maths encoded into language is just a set of meaningless rules you have to memorize, but when you process it in concept-space the ideas behind maths make so much more sense. So, if you have someone who processes stuff mainly through language, their speed of learning math is significantly slower than someone who processes them in concept-space.
