Earlier quoted context omitted.
I, and I think many other people, didn't really 'work' at learning to type. We just practiced as a side effect of using the computer rather than, say, taking typing lessons. For someone like me, QWERTY has a difficulty curve. I think seno technically wouldn't have a curve. The inability to hunt and peck means that without explicitly setting aside time to train in steno, there isn't any way to make real progress. Math…
I never learned to write on a keyboard in a controlled way and I still can't 'touch type' naturally. I tried to learn in, but I always fall back to my old habits since my right hand hurt otherwise. I don't think I will ever bother getting fast. It is probably way better to learn it properly from the beginning.
Forcing myself to stop looking at the keys initially increased error rate to an unacceptable/demotivating level, but in a couple of weeks I was touch typing quite a bit faster than I could hunt and peck with no loss in accuracy.
