I've used to work with a guy who had... dyslexia, I think? Dysgraphia? Basically, he simply couldn't type without typos, although he seemed to do fine with reading. Well, he relied heavily on copy-pasting code snippets around, those sometimes being as small as a single keyword. Quite a sight to see, to be fair.

My point is, being able to type 100 WPM without typos is surely nice, and so is e.g. having good vision (or vision at all, for that matter), but it's not strictly necessary and can be worked around. Although, of course, if you can come into possession of those qualities reasonably cheaply then sure, go on and obtain them.
