I don't think this is what the person you responded to is asking.

Their question is more, "why would I buy a digital camera that takes pictures in a new format that only a few cameras understand? All my tooling, 3rd parties, and other camera I own use the standard format. Even though I can see why the new format has advantages, I am still going to have to use the other format for all these other photos I have to work with, and there aren't equivalent tools in the new format for all these other photos things I need to do. Even if I buy this new camera, I am still going to have to work with the old format, so I'll have to learn how to use two formats now, and get used to two tool chains. Since the existing format is something I am going to have to use either way, how is it worth it for me to have to use two formats?"

[stavros]

You don't have two formats, though. Jj transparently works with git. I use it for everything and none of my collaborators is even aware that I'm using jj.

[mcepl]

If you say that you can work only with JJ and never use git, you are delusional. For one, where is that JJ forge (i.e., the equivalent of Sourcehut)?

[Macha]

GitHub, or sourcehut, or whatever you prefer.

Maybe you feel that jj git fetch and jj git push are using "git" but it means you avoid the git cli in favour of the IMO better designed jj cli.

I could respond to this uselessly pedantic comment, but then nobody wins.

[mcepl]

I didn’t mean to be pedantic. My experience with Jujutsu was as bad as with Mercurial (and hg-git, I believe?) … after couple of hours working with my repo (https://git.sr.ht/~mcepl/m2crypto), looking at it with git, I got incomprehensible mess of destroyed multiple unmergeable heads (especially for Mercurial), and completely destroyed other branches, where I was not planning to work (Jujutsu). The only resolution in both case was export my work to plain patches, rm -r the checkout, clone again with git and forget anything about those other VCSes.

So, I claim that Jujutsu actually doesn’t work well with git repositories (and forges) very well, and I would like to see a native one.

[stavros]

It works fine for my use case, all my Github repos are in the state I'd expect, and I sometimes use git in my local repos as well, and that works fine. Hell, sometimes I use jj to fix a mess I made in git.

The only issue is being in detached HEAD all the time, but in practice it's not a big problem for me.

[steveklabnik]

I am very confused as to what happened to you here, that’s not usual.

Most of jj’s stuff is purely local. I woke on GitHub with jj just fine, the only thing people notice is that my autogenerated branch named are a bit odd.
