After watching this I can kind of understand how a blind person would write new code. But I find so much of working on a team with a large codebase is about hunting through mass quantities of code without really knowing what you are looking for, which always seemed like a very visual process to me. Sometimes I find myself scrolling through a 2000 line file looking for a particular shape of the code that I would not even be able to articulate but know it when I see it. I'd be really curious to know how a blind person navigates a large, unfamiliar codebase.
