Having volunteered to teach kids coming from single-parent household with no computer at home, I've seen how the inability to type on a QWERTY keyboard with any modicum of speed (hunt-and-peck) actually limits them when we encourage them to 'iterate', 'try fast and fail', 'just code a line of something', or 'what will that do?'. If expressing your thoughts and intentions to the editor is painful and slow, it is a concrete barrier to learning how to fail faster.
I can give you an opposite anecdote from personal experience. I learned how to program at 12 not learning how to touch type correctly. Guess what? I’ve been programming for 30 years and still can’t “properly” touch type. I’ve typed with one hand all of my life (not by choice) and it hasnt slowed my career down. With modern IDE’s and autocompletion, my typing speed hasn’t been a hindrance.
