I'd like to believe, given that the largest part of the brain is devoted to visual processing, that it gets freed up for memory\creativity etc.

Given the right kind of guidance and development people with "disabilities" could bring a very unique perspective and new ways of thinking to problems and algorithms.

Deaf people for example think visually from birth as they have never heard sound. And we still don't even have a good way of representing sign language on paper or digitally.
