Keyboard Layouts

Lets say you have 2 computers, one uses qwerty layout and the other one dvorak: can you quickly switch between the two without getting used to one or the other?

I heard it is also good for english-speakers. Do you think its good, or does it have weakness in your workflows?

Like everyone I started with qwerty for ~ 10 years, then in college a friend introduced me to dvorak. I didn't pick it up at first, but after I started working and realized all my time was spent at the keyboard, I learned it in earnest and got back up to my original speed.

Around 2017 I learned about halmak, which was the first AI designed (genetic algorithm, not gen AI) layout, designed to minimize hand movement, and I learned it quickly and loved it for several years.

About a year ago I decided to try out a new one, since halmak has so many same finger bigrams. So I bounced around between a few, but now settled on graphite, as a lot of ppl on the reddit keyboardlayouts community recommended it. I've been on it for ~3 months now, and like it a lot.
