Like? This isn't explained, I'm curious on why I would want to use it, but this is just an empty platitude, doesn't really give me a reason to try.
IMO, the authors and evangelists of Git are essentially correct when they argue about its power.
However, I think that it's extremely difficult to gain practical experience with using Git in a high-powered, high-agency way, mostly because there are a lot of abstract concepts at play and there is no easily accessible place where these concepts can be "discovered".
Basically, Git is as good as it's cracked up to be, but only if you're an expert.
If you're interested in becoming a Git expert, I cannot recommend Emacs Magit strongly enough.
If not, I think Jujutsu could be an quicker road to a high-agency version control workflow. It's at least worth considering. I feel confident that Jujutsu can succeed, in particular because of Git's harsh difficulty curve.
And then Jujutsu came along and casually doubled my VCS productivity. I didn't see it coming!
I am interested to know, because there seem to be a small number of people who really seem to like it, and up to this point I haven't been able to understand what it is that they are all so excited about.
In git, if you get a conflict, you feel like you have to resolve it now.
With jj, most of the times I get merge conflicts, I simply ignore them and deal with them later. A conflict is not at all a blocker.
I guess I view that as a positive rather than a negative. I'm not saying that dealing with merge conflicts is a picnic -- it isn't. I just find it difficult to believe that ignoring them and resolving them later will improve the situation in the long run.
But really, it’s about something deeper: rebase is a first-class operation in memory, and not a serious of patch applications via the file system. They’re therefore lightning quick, and will always succeed, which is nice. If you get partway through resolving a conflict and want to change to something else for some reason, that’s possible and simple.
with jj, you have the option to fix half of it and come back later. you can take a look and see how bad the conflicts are if you go a certain route and compare to another option
Typically for me, "later" means "immediately after the rebase command has finished", which is very similar to git's "while the rebase command is running", but has some subtle and important differences.
For example, because the rebase completes first, I get to see roughly what the end-state of the rebase is before I start doing the hard work of fixing conflicts. This is useful as a sanity check - sometimes the reason I'm getting a bunch of merge conflicts is because I was rebasing the wrong things in the first place and included an extra commit somewhere. Seeing the result first gives me the chance to sanity check what I'm doing.
Another thing is that my repository is never in a broken state where I can't continue doing other things. There's no way in git to stash a rebase, say because I've realised a different approach might work better or just because I urgently need to work on something different. I either need to cancel the rebase and start it again later, or keep on going until it's over. In jj, because the conflicts are automatically checked in as part of the commits, I can easily jump backwards and forwards between the work I'm doing resolving my conflicts, and anything else.
Another way of thinking about it is that git is very modal. You check out a branch and are in the "branch" mode, and then you start a rebase and are in the "rebase" mode, and then you do a bisection and are in the "bisect" mode - it's difficult to move freely between these modes, and there's certain things you can only do in some modes and can't do in others. In contrast, jj has exactly one mode: "there is a commit checked out". The different operations like rebasing all happen atomically, so you never see the halfway state. But because things like conflicts can be encoded in the commit itself, you still have all the same power that the modal approach had, just with a simpler conceptual model.
