I was never trained as a touch-typist. I still have to look at the keyboard as I type, and have never become a master CLI maven.

But it hasn’t prevented me from writing thousands of pages of prose, and millions of lines of code.

I think it has probably also saved me from RSI. I have a friend that is a master engineer, that has to change their career, because their arms are all screwed up (multiple surgeries didn’t fix it).
