It took months before I was 'up to speed'. I thought I would type significantly faster, but that is'nt the case as I often think slower then that I can type. It's much more about comfort. I don't regret it, it really is more comfortable. I switch between QWERTY and DVORAK-IU often so I am bilingual. Typing in alphabetic shorthand (for example Yash) with yet another optimized layout is another possibility. Or Yash with morse code or braille mapped like chording or just chording. https://www.artofchording.com/layout/chorded-keyboard.html
Soon we will be talking to our LLM's a lot, so it's not a real big deal, but the nerd in me likes to optimize. Still I think, perhaps I could have designed the very best layout for my personal style and Dutch en English and the latest theories regarding what's more optimal (rolls, hand alteration, compression, chording). Perhaps an LLM can help? Not sure if I want to learn a new layout again. In the meantime alternating between QWERTY and DVORAK-IU suits me well.
