Beyond the Wrist: Debugging RSI

You don't hear much about it now. Is it because treatment improved, or we use keyboards with much less travel, or there's better general awareness of ergonomics, or that there's more mouse/trackpad use mixed in with typing now? Or is it something else?
Device of choice did not make a big difference, except for one: having a secondary standing desk with a treadmill. I took that from an old Linus Torvalds interview, it's a small monetary investment, but a big health one. The biggest downside is that it takes a lot of space. In my case, the main problem was linked to prolonged pressure on a few key points, a problem that doesn't really occur when moving.
Before that, I used to have a laptop so that I could spend the work day in different postures, move to a couch, etc.
Regarding the article, I can confirm that pain was in different modes during these different periods, but that also matches the risk of physical damage. I feel that as long as you're just doing a half-hearted effort that is just an attempt to deceive your body, pain will only worsen. It's only after you learn to listen to the pain that the real progress is made.
In my case it took me a good 5-6 years to figure this out. Then I started working on my overall posture, and my issues virtually disappeared over night. A friend of mine, who was also struggling with RSI a couple years later, ended up following the same protocol and he, too, is 100% painfree these days.
Where does one get one's posture checked? I'm 100% serious is this something a doctor can do?
Second, if we assume my posture is terrible - which well, I basically walk looking down at my feet all the time - so you can think of me as the human equivalent of the Leaning Tower. How do you go about fixing it? I mean, I can walk straight which feels weird, but I'll forget about it in 5-10 seconds and go back to being the human equivalent of the Leaning Tower.
What did you do to fix your posture?
If you work for a large company and they don't provide this, well, they don't care about your health.
Maybe someone else knows how to get an ergonomic assessment done outside of the office
The most important changes I made in my life which fixed RSI related issues (carpal, tendonitis, etc) permanently were:
- Proper ergonomic keyboard (consider a split layout)
- Posture (Alexander technique, Taubman technique)
- Trigger point therapy (with a Knobble tool)
I can highly recommend this book:

Then he quit the job he hated, got a job he enjoyed (both coding), and his RSI went away in a week. Sometimes it really is psychosomatic (which doesn't mean the pain is fake).
Personally I've had mild wrist pain since college (10+ years). Decent posture, a reasonable keyboard, letting my arms form a natural angle, and floating my wrists above the keyboard seems to help. My hands cramp up after 20min of typing in a narrow airplane seat for example. But I can type for hours on my ipad magic keyboard in my lap or my ergonomic mechanical keyboard just fine.
Maybe half a thinkpad would be a decent keyboard format, if it's wireless and a bit ergonomically formed to fit the legs?
Try a combination of heavy weightlifting, HIIT, and optionally SSRIs.
