> JJ might be good (this article couldn't convey why in the "What is jj and why should I care?" page) but it's not 10x better than git, so it will likely die. Sorry, nothing personal, Mercurial/hg was a little bit better than git and died too. Network effects.

The difference is that I can (and do) use `jj` with existing git repos today without needing anyone else using the repo to change what they're doing. There's no need to replace something when it can exist alongside it indefinitely.

Unless you need to work with a repo that uses submodules or lfs.
