And yet, here you are, not ignoring people who are apparently fad-followers!

jj is not new, nor a fad. And, moreover, its not "just" an abstraction - you would know this if you actually read my comment. jj is built on top of git and incorporates concepts from mercurial and elsewhere. There's ample writing in the github readme, docs and lots of thoughtful essays and manuals created about jj. But becoming informed is clearly not something you have much interest in.

Most laughable is that you seemingly created this account JUST to make this comment.

Thanks for providing a perfect example of the most common detractors of jj

you do you, friend
