It might be that the cortex operates in much the same
way in different regions, barring certain specialities such as
the cytochrome-oxidase blobs in V1. But the rest of the brain
is modular and task-specific. I don't know which is harder to
deal with - uniform computational principles in a distributed
non-modular design, or diverse modules.

BTW, Marr's contribution is inaccessible to scientists nowadays -
his 1982 book /Vision/ has been out of print for decades,
and used copies sell for about $300. I don't have one.
