> The nervous system is cross-wired [...] I asked my doctor last week why this should be, all I got was a shrug. So I asked Catherine Carr, a neuroscientist at the University of Maryland, College Park. “No good answer,” she replied. After reading the piece, as he's proposition a potential theory based on mathematics and elegance of the solution, her reply still feels totally apt. That makes the title slightly misrepresent what he's trying to convey. We don't get the why, just a maybe. Otherwise I'm not sure 3d mapping simplicity is enough of an answer when the brain can also adapt to way more complicated configurations when receiving partial damage for instance. It also feels like we have very few organs that developped along the most simple solution
