It's totally compatible though, and that's a big selling point. I use jj and nobody else at my work uses it and that has never been an issue.
For jujutsu, it's fine on your own computer, but you probably have to use git in the CI or on remote servers. And you probably started with git, so moving to jujutsu was an added effort (similar to dvorak).
That's not a problem, just switch to Qwerty when you use a different computer. For me at least, it's not hard at all to switch between Dvorak and Qwerty.
Sure, but you had to learn both. And what benefit did you get from learning Dvorak?
I feel the same with jujutsu: I have to learn it on top of git, and I don't see a lot of benefits from knowing it.
Same deal with jj vs. git. I've learned git. I've used it for 15 years. I'm proficient with it. I'm sure jj is better - but I'm not sure it's better enough to be worthwhile.
More comfortable typing, less wrist strain, etc. It's just a better layout.
