I was scared to learn but then a coworker taught me the 4 commands I care about (jj new, jj undo, jj edit, jj log) and now I can't imagine going back to plain git.

Obviously the working tree should be a commit like any other! It just makes sense!

Do it. It's absolutely worth it. You can pick it up in 30 minutes and have full proficiency in an afternoon

It’s not so much biting the bullet as eating the delicious chocolate.

Took me a month to learn jujutsu. Was initially a skeptic but pulled through. Git was always easy to me. Its model somehow just clicks in my brain. So when I first switched to jj, it made a lot of easy things hard due to the lack of staging (which is often part of my workflow). But now I see the value & it really does make hard things easy. My commit history is much cleaner for one.

Well, Graphite solves the problem of how to keep your stack of GitHub pull requests in sync while you squash merge the lowest pull request in the stack; which as far as I know jujutsu does not help with.
