I'm getting pretty good with Emacs, but I find its Treesitter handling a bit obtuse, and the auto-installation package I found slowed the editor down a lot for reasons I can't determine. (I mean, everything slowed down, and it all sped up again when I uninstalled the package.) I'm looking forward to revisiting this when Emacs 31 comes out, though.

I also don't think I'd ever call configuring Emacs "trivial" compared to more modern editors. Matching the out-of-box experience of something like VS Code or Panic Nova requires some work. This isn't really a knock against Emacs, but I think Emacs fans -- myself included -- need to be honest about that. It's quite possible I would have picked up Emacs years earlier if I hadn't been given the impression that it was just super duper easy, especially once you picked a starter pack. It is not, it probably never will be, and I've come to believe that starter packs are actually a bad idea for most new users. If you don't understand just what it is you're putting in your init.el file and why, then if you run into problems, it's going to be way harder to figure out how to fix them.

Being many things, even if "easy to install" individually, can add up to a hassle to pick, research, install, and configure them.
