I come out of the woodworks every now and again whenever I see Dvorak mentioned in any context. I really despise its popularity as an alternative keyboard layout because I feel it wasted a good year of my life.

1) Few people will have benefit of learning Dvorak. What benefits they see comes from learning how to properly touch type by forcefully breaking bad habits with their original (usually QWERTY) keyboard layout.

2) Switch to Colemak or any more modern layout that takes advantage of bigrams/trigrams better. Colemak is genuinely superior to QWERTY beyond just learning to touch type.

I used to type 170~ WPM on QWERTY. Sustained. By all means an accomplished typist. I learned Dvorak well enough to get back up to 120~ WPM but saw no real benefits of using it: I already knew how to touch type. But QWERTY was causing my hands to cramp up over time and so I was on the search for improving that. I gave Colemak a try and it was a great relief. I only type 150~ WPM on Colemak after some years of using it but the lack of pain from typing for long periods of time is worth the small hit to my typing speed.

Almost every single person I see who touts benefits of learning Dvorak was typing <60WPM in QWERTY and did not know how to properly touch type. The benefits they see weren't from using Dvorak: it was from finally learning how to touch type properly.

Apologies as I know Dvorak wasn't really the focus of your post here. But in an attempt to perhaps make it still relevant: change every now and then is good. It can break you out of bad habits you didn't know you had learned and sometimes open you up to new ways of accomplishing something. As other replies have mentioned - I'm a big fan of Helix and gave up Neovim for it.
