I think I can make an argument that trying to do most things on a keyboard will result in faster workflows and less wrist strain, but to do so feels similar to the arguments I have about avoiding super-googlifying your life, preference for using communication solutions like Signal rather than captured applications like messenger or instagram, recommending libre software, etc. For whatever reasons, normies just wanna slide fingers on trackpad / upload their faces to companies / give up their software rights!

Maybe I'm off base but I really feel similarly about keyboard usage as I do to other "nerd shit" like above. The best argument I've ever heard for it though was from the World of Warcraft days: people who click their spells with their mouse, rather than using extensive keybindings (you have more than 9 spells so need to involve shift, ctrl, and start using the keys around wasd as well), you would simply never be as good as a keyboard user. We called mouse-users "clickers" as a derogatory term. I started as a clicker (like most kids I'm sure) and was so astounded by how much better I got at the game, and how much easier it was to play, when I got used to keyboard bindings for spells, that I started trying it in other software, like MS word and power point. "Clickers suck" was a trueism there too, and so from like age 13 on I've always been the kind of person to invest maybe 5 minutes to an hour learning a new software's keybindings and I think it's paid dividends.
