These days I see a renaissance of sorts. First, the development progress is excellent. Second, Emacs turned out to be the ultimate material for AI. I no longer write my own Emacs functions. I tell AI to modify the Emacs behavior the way I want. I now have a development environment that I fully control. Windows open where I want them. Keystrokes do what I want them to do. I have tools for annotating Claude Code plans in Emacs and plenty of other functionality. Without AI, I would never be able to implement all these tiny fixes and improvements. It would cost me too much time. And in other IDEs, I would have to "ask for permission", because not every behavior is exposed and modifiable. In Emacs, almost everything is, and you can change the behavior of other packages, too.
It feels great to have a development environment that I am in control of and that won't disappear tomorrow, like so many other IDEs did.
Since I started using Ghostel, my Claude Code and Codex sessions started gradually migrating into Emacs. They work just as well as in a terminal and managing them is more convenient. This is also why I can't really find any use for all those newfangled tools that are intended to help with managing multiple coding sessions.
you don't need that, you can use an acp (agent-client protocol) client like agent-shell - https://github.com/xenodium/agent-shell
I've tried it with cursor and it works okay.
I don't use it much for development these days, but I always have a bunch of buffers open and I do a lot of residual work on it.
If I install Linux on my computer, the first thing I always do is install Emacs, it's like a kind of default environment for doing everything text related, and it feels incredibly unfamiliar not to have it open all the time.
