I’ve been loving it for personal projects. But for work, some of our homebrew tooling relies heavily on hashes. So any operation that causes snapshotting to occur tends to lead to breakage that utterly confounds Claude. I tried giving it rules and instructions to make sure to sync git up to the correct commit for the current snapshot, but as soon as the signal for that is too week in the context it blows a gasket trying to figure out what has gone wrong.

> Trying out jj is super low-risk--since it uses git as a backend, you can test it out and bail back to git without any drawbacks other than a detached head state.

Btw, the risk of trying out other modern version control systems is nearly as low: most of them are compatible with git and you can convert back and forth. That definitely includes mercurial etc.

People tried mercurial. They went back to git.

Some did, sure. I made a more limited claim: you can convert back and forth between mercurial and git.

> Some did, sure.

Not some. I mean, even the few source code repository services that supported mercurial started dropping it.

See Bitbucket's announcement:

https://www.atlassian.com/blog/bitbucket/sunsetting-mercuria...

> According to a Stack Overflow Developer Survey, almost 90% of developers use Git, while Mercurial is the least popular version control system with only about 3% developer adoption. In fact, Mercurial usage on Bitbucket is steadily declining, and the percentage of new Bitbucket users choosing Mercurial has fallen to less than 1%.

I tried Sapling (Facebook's fork of mercurial with more polished git-compatibility layers) and never looked back for any of my own projects.

I recently started a new job where the vanilla git CLI is the only git frontend installed on company servers, and the regressions in user-experience are painful :(

I tried out with a tiny project. It is the muscle memory built up with Git that kicks in and wish that JJ does it. I went through all the raw mistakes and doing things the hard way with Git, that, my mind plays trick trying to use JJ with the Git mindset. For now, I have mapped all of my Git aliases to JJ equivalent. But I would like to learn it the right way and do it the JJ way. This is going to take time, I’ll go slow.

I really recommend just ripping off the band-aid and using jj "as intended". It took me only a day or two to adapt, and a week to feel like I am now a jj native. It's really a tiny cost to pay, and way less than the overhead of maintaining a bidirectional mental mapping between jj and git.

As others have said before, I used Magit in emacs and thay already feels like a superpower compared to git alone.
