Yup, don’t. People already covered why. I will add that I tried learning dvorak for quite a while and it didn’t stick until I went cold turkey. It was very frustrating hunting and pecking for a couple days, but I made pretty quick progress. IIRC I was back up to 20-30 wpm after a week which was “usable” at least, and back to 60-70 wpm after a month. I had regular wrist pain before switching, and it was basically gone after. I don’t think it helped my typing speed. Like I can do 90 in bursts for a bit longer, but generally I “cruise” much slower than that. ;)
