I switched from Qwerty to Dvorak in my 20s, and now from Vim to Helix in my 30s. Both transitions were rough for a couple of weeks, but honestly less difficult than expected. Neither choice turned me into a 10x developer, but neither one has ever caused a problem that I cared about either.

Do you spend a lot of time on systems that you don't control? Dvorak discourages other people from helping themselves to my keyboard, which is honestly worth more to me than being able to go the opposite direction.
