I love this stuff as a hobbyist, but professionally I can't help but think this is all obsolete in the age of agent-driven development. I wish jj was around a decade ago.

I disagree. Easily reviewing and combining multiple streams of parallel work is more valuable than ever.

Been trying to get into jj lately, but I rely a lot on VS Code's git gutter to review changes as I code. Doesn't look like jj has an equivalent in VS Code. Anyone got tool recommendations?

With jj worktrees, you can even have agents working on each of those sub-megamerge branches in parallel.

I've been playing around with agent-native source annotation to specifically address the massively parallel work problem. Check it out here: https://github.com/draxl-org/draxl

Great writeup! I've been using `jj parallelize` [1] a lot (and wrote about it here [2]) to fan out a sequence of commits to set up a megamerge, but your stack alias sounds super useful to create them on the fly, rather than at the very end of a work stream. Thanks for the tips!
