But it was just a bit too much cognitive dissonance for me to try it.
It seems like the next big thing is parallel coding... I've tried GitButler, Spectator, Vibe-Kanban, and Conductor in the past week. And there is now FleetCode.
I liked Spectator's idea (use a separate docker container for each) but it didn't quite work right. So back to worktrees which seem to work just fine.
At some point, we will probably consolidate on 2-3 dominant tools in this space.
I wonder if even work trees will be needed if we can do a "create a copy-on-write version of my code folder" which would result in nearly zero-cost copies of the repo.
