If you really typed 20 hours a day for three years (or anything close to that), it weren't the rubber domes what damaged your fingers, it was you. Typing without breaks, stretching and proper technique is... insane.
I am a coder. I take giant breaks all the time. I always have to invent some new algorithm that requires long long periods of thought. So I took lots of breaks. Besides my legs or feet or knees would get sore if I sat down for very long at the puter (typically 1 hour, restless leg syndrome) so I would not just take a typing break but actually take a break from the whole computer and go for a walk to think or eat.
And when I did those 20 hour days I would sleep for 12 hours typically.
But they were not all 20 hour days. Some days were only 8 or 12 hours.
In any event I never said it was the rubber domes that hurt me. It was the
impact of smashing a hard piece of plastic down into an immoveable object. This is referred to as a "collision". The force graph looks like this:

See how it just suddenly turns into a straight line upwards? That is called smashing. If you encounter 70cN of resistance and then suddenly hit 1000 cN of resistance that is called smashing into a wall.
BTW professional musicians often have similar issues — in that case, they're usually told to go back to their teacher and relearn proper technique. Better tools (keyboards, keyboard layouts etc.) can't replace that, only reduce consequences.
To answer your question, I didn't have to train myself at all. I started to type like I always did (I never smash keys like if my fingers were hammers),
I don't think anyone does that. Except maybe keyboard gamers?
I am not a keyboard gamer. I use a proper controller or I don't play.
... and it felt great.
u just sat down at cherry reds and did not bang the key into the metal plate? The one that is 4mm away from rest position? Dewd u r awesome.
