alt Hacker NewsI think I'm missing some major selling point of jj, to me it's just git with a different flow that might be more suitable for a rare few cases where heavy parallel work is happening, and even then git is fine if people know what they're doing, the idea of no staging areas doesn't appeal to me, mutable commits seems actively negative to me personally.
I understand if people are enjoying it great, but the amount of praise and 'this is revolutionary' comments I see makes me really feel I'm missing a beat.

Don't necessarily need heavy parallel work, or even anything parallel, to make use of jj; it's very nice for even just manipulating one local sequence of commits (splitting commits up, reordering them, moving files/hunks/lines between them or into/out of the working copy, without needing to checkout anything).
Won't get you much if you don't like to mutate commits in general, of course; at that point it's just a different committing workflow, which some may like and some dislike. (I for one am so extremely-happy with the history-rewriting capabilities that I've written some scripts for reinventing back a staging area as a commit, and am fine to struggle along with all the things I don't like about jj's auto-tracking)
As a fun note, git 2.54 released yesterday, adding `git history reword` and `git history split` in the style of jj (except less powerful because of git limitations) because a git dev discovered jj.
Did you read the article?
> Basically, in the megamerge workflow you are rarely working directly off the tips of your branches. Instead, you create an octopus merge commit (hereafter referred to as “the megamerge”) as the child of every working branch you care about. This means bugfixes, feature branches, branches you’re waiting on PRs for, other peoples’ branches you need your code to work with, local environment setup branches, even private commits that may not be or belong in any branch. Everything you care about goes in the megamerge. It’s important to remember that you don’t push the megamerge, only the branches it composes.
> You are always working on the combined sum of all of your work. This means that if your working copy compiles and runs without issue, you know that your work will all interact without issue.
You don't even push the megamerge to the origin. Or perhaps you don't even need to push it. You can just... work off it.
You have to look at it from the workflow side not compare the tool on your current git workflow. Check out https://www.stacking.dev for a description of stacked commits, which is more the everyday workflow on jj than the octopus in this article.
