Working with Martin has been a real pleasure, and we'll have some more stuff to talk about very soon!

I absolutely love jj (just check my HN comment history). One thing I'd love to see in jj though that git does better is copy tracking. If somebody renames a file upstream, and you go to rebase your commit that touches that file onto main, jj doesn't handle this very well compared to git.
Do you have any idea if this is coming to jj soon?
There is active work in this area, yes! https://github.com/jj-vcs/jj/issues/3386 is the bug tracking the feature request, and there have been some recent PRs working on implementing this, see here for one example: https://github.com/jj-vcs/jj/pull/9864

Do you happen to have or know of any good open source projects on any public platform like GitHub, gitlab or Codeberg, that uses Jujutsu/jj?
It's hard to tell since any given dev can just use jj locally, if they want to, while everyone else uses git.

Checkout Gisia https://github.com/gisiahq/gisia
If I remember correctly, Mitchell Hashimoto uses it for Ghostty (probably under the git backend).
jj uses git as a backend. None of those need to "use" jj. You can use jj in an existing git repo, with your git wielding friends.
excited for what you guys would be coming up with ;)
btw, did Martin leave google?
Thanks!
Martin left Google for this, yes.
Wasn't it partially owned by Google? Or are they just a contributer now?

Will this have any chance if Jujutsu/jj doesn't get more traction? The effort to learn a new VCS is less than for a programming language, but many developers have not learned git in depth, and Mercurial and others have not gained a lot of traction.
I'd argue that the reason a lot of developers have not learned git in depth is because it's actually kind of terrible from a UX standpoint (lots of inconsistent naming of things and somewhat leaky abstractions), and that Mercurial faced an uphill battle in large part because it lacked compatibility with what people were already using. I haven't used Mercurial, but from what I've heard quite a lot of how jj does things is similar to Mercurial, just in a way that's compatible with git. I haven't used git directly for over a year in favor of using jj despite exclusively using git repositories, and no one I've worked with has even needed to be aware.

Not really. I remember my early years with git and the favt was that I never needed more than clone, add, commit, pull and push. While I’ve done some mistakes that got ne to learn more, especially with creating branches and undoing. I’ve never needed a lot, even when I started using GUI which exposed more concepts.
Why? Because I have no understanding of version management and how it’s useful in a dev workflow/release process. I was just using it for checking in work.
Since then, I’ve read the “Pro Git” book, learned how devs and teams handle versioning and devel a good understanding of how git can help me in my coding process and general software development. And it’s very good at what it does.

They have less to walk away from then.
It doesn't require that everyone switch at the same time, unlike other VCSs.
