> I see analogy to guitar playing here. No matter how well you figure out finger positioning for a complex passage, you won't be playing with ease unless your elbow, wrist and spine are also positioned properly.

This is a good analogy, and instrument players all hit the fatigue issue.

On top of posture, a lot of the pro players seem to manage it with a mix of:

- regular muscle training to protect articulations

- regular resting periods and avoiding activities that hit the same moves

- medication as soon as there is any sign of things going wrong

I think there is no magic bullet (or magic keyboard/mice combination), and switching to an "ergonomic" setup is only a small part of the solution for most of us. ATP had a pretty good take on this in their 'ask app' section https://atp.fm/377
