I’ve never had an issue with that. I spend more typing that thinking unlike a data entry person or someone who types all day long, my fingers get plenty of rest between using vim for everything and just being a developer.
It seems to mostly be a problem with home-row typists having to twist their wrists to hit some keys.
I'm self taught through online games like StarCraft and don't use the home row - my hands settle in a different location, I use the edges of the keyboard for positioning (mostly through peripheral vision rather than touch), and I use my elbows and shoulders in addition to my wrists to move across the keyboard. Don't have to stretch or twist my fingers and wrists into awkward positions that cause strain, never had the issues others describe, and so far no hint I'll develop them.
