Pretty much everything you do often enough will be automated away from conscious thought.

It ends up in a weird situation where if someone asks what the keyboard binding for, say, inserting a row into a org-mode table, I wouldn't be able to answer. Something with maybe a c in it, and a '-', not sure? Yet, once in the situation that needs it, the fingers move by themselves.

Also related, musicians don't spend two seconds figuring out how to play a note.

Musicians also regularly play all the notes on their instrument. There are many once/week tasks that you’ll spend more time trying to remember the shortcut you used last week than just grabbing the rodent.

Sure, but one of my most commonly used keyboard short cuts is the one that pops up a fuzzy search over all the available actions/settings. Whereas with the mouse i have to dig trough a ton of sub menus and often even have to google to find what I want.

I guess that study from 1989 didn't take up existence of fzf into account.

"Sure ctrl z everyones got down. "

Not really.
