Because not everyone has time to dedicate to a skill with diminishing returns after a certain point, and on top of that many people do not at all care about the life of their keyboard.
I touch-type, but still occasionally struggle with some things eg. using the right shift key instead of always preferring the left. I don't see much benefit in addressing this, since my typing speed is never the blocker with regard to my programming output.
I'm eternally grateful for Mrs. Walker's 2nd grade class, where they shoved us in a room full of Apple 2e's and made us play a typing game (and if you finished, you got to play Oregon Trail). I'm a bit surprised/disappointed that touch typing isn't universally taught in school.
Isn’t it distracting to have to look and visually think about the keyboard in the midst of working? Genuinely asking. I literally can’t imagine having to look at the keyboard. And how much of a commitment is it really?
It might be a bit distracting, depending on the person. Personally, I am still thinking about stuff and perhaps seeing the image on the screen or another one of some concept in my mind, when I check the keyboard. Sometimes it might even help to not look at that screen for a moment.
