alt Hacker NewsClaude has really helped me improve my Emacs config (elisp) substantially, and sometimes even fix issues I've found in packages. My emacs setup is best it has ever been. Can't say it just works and produces the best solution and sometimes it would f** up with closing parens or even make things up (e.g. it suggest load-theme-hook which doesn't exist). But overall, changing things in Emacs and learning elisp is definitely much easier for me (I'm not good with elisp, but pretty good Racket programmer).
I used Emacs for about a decade and then switched to VS Code about eight years ago. I was curious about the state of Claude Code integration with Emacs, so I installed it to try out a couple of the Claude packages. My old .emacs.d that I toiled many hours to build is somewhere on some old hard drive, so I decided to just use Claude code to configure Emacs from scratch with a set of sane defaults.
I proceeded to spend about 45 minutes configuring Emacs. Not because Claude struggled with it, but because Claude was amazing at it and I just kept pushing it well beyond sane default territory. It was weirdly enthralling to have Claude nail customizations that I wouldn't have even bothered trying back in the day due to my poor elisp skills. It was a genuinely fun little exercise. But I went back to VS Code.
