You're not wrong; I've actually thought about that.
Fortunately my RSI is starting to get better. Therapeutic massage and shoulder rehab exercises have made a big difference (I had a bike accident a few years back, and my shoulders were in pretty bad shape).
I stopped typing on my 2018 MacBook Pro's keyboard (which I think contributed to my problems), and exclusively use an ErgoDox. I've also been taking Magnesium as well as NSAIDs to reduce inflammation. Still a daily struggle, but I can type posts like this one without too much pain.
