Busted my Corne-ish Zen yesterday, going back to an Ergodox EZ (until I received 2 new Corne, including one as backup) I can tell that leaving a comfortable and efficient hand based setup is literal pain, both physiological and cognitive. I write and code using Vim (so navigation with keys) and browse with Tridactyl (same principle). It's very rough going back.<p>Also I work in XR and rely heavily on hand tracking and I'm precisely trying to use that accident so re-consider what does typing mean without a keyboard. How can one use hand tracking in XR as input without relying a virtual keyboard, which is so slow and lacks tactile feedback.<p>Anyway, all this to say yes, ours hands are impressively precise, fast, flexible. We take them for granted but it's definitely worth spending a bit of time training them, considering the interfaces at different level, ergonomic, physical interface, firmware, then the software with its UI.
