That's not a fair example at all since hearing doesn't have an obvious relevance to coding, it's a mostly mental/visual activity (+ the physical activity of typing the code).

Schizoprenia on the other hand impacts the exact same faculty that is the most important one for programming, the brain. I don't think it's ignorant to be fascinated over how his illness so severly impacts his though processes while writing (and living), but apparently not while coding.
