Not op, but had a very similar story. Got crippling RSI to welcome me into my 30s. Couldn’t work for several months and ended up getting a Glove80 because I needed to make a living.

This definitely does not describe me. I typed around 100wpm, sometimes quite loud, often times quite a button mash, and frequently not lifting my fingers quickly after each press. Didn’t have any notion of “correct” typing
