Not parent, but for me it was a couple hours of reading (jj docs and steve's tutorial), another couple hours playing around with a test repo, then a couple weeks using it in place of git on actual projects where I was a bit slower. After that it's been all net positive. Been using it on top of git, collaborating with people via Github repos for ~11 mos now. I'm more efficient than I was in git, and it's a smoother experience. Every once and a while I'll hit something that I have to dig into, but the Discord is great for help. I don't ever want to go back to git. And yes, jj on top of git in colocated repos (https://jj-vcs.github.io/jj/v0.27.0/git-compatibility/#co-located-jujutsugit-repos https://jj-vcs.github.io/jj/v0.27.0/git-compatibility/#co-lo...). If you set explicit bookmark/branch names when pushing to git remotes, no one can tell you use jj.
