I lost track of what happened there (moved to Vim back then), was it VSCode that killed it?
For what it's worth, I went from ST3 -> VSCode -> ST4, and have been happy since. I've found that I prefer my text editor with minimal extensions, and with Sublime Text's LSP Plugin, I'm pretty content. The performance and customizable UI make it more worth it to me than VSCode.
With that being said, just a quick look at, for example Stack Overflow 2025 survey tells me it doesn't have the same mindshare it once had.
There needs to be a critical mass of people using it for things that aren't core to stay updated
The key plugins I use are some LSP servers, and they work wonders. The few languages I mainly use (yaml, json, TS/JS, python and Go) I get great language support for via the LSP servers and the editor is blissfully fast always.
I could live without even the LSP stuff, but the one feature I can't live without is Sublime's excellent recovery support. Every once in a while my system will crash, and even though I've had multiple unsaved buffers Sublime recovers them every single time. Saved my butt more times than I want to know!
I remember the extremes of the utter unconstrained chaos of Emacs and the rigid ultra-high-boilerplate approach of the Eclipse IDE. Emacs was fun to hack on, but impractical to use as an IDE, because if you installed enough plugins to make it useful as an IDE, it was broken half the time (my experience, many years ago.) Eclipse had a robust architecture, but writing plugins for it was a dispiriting slog, even when I got paid for it (again, my experience, many years ago.)
Unironically, maybe VS Code.
Everything simple you can do with it, either comes built-in, or within Github/Microsoft ecosystem, or has an official plugin that gets recommended and featured by the editor itself. Plugins from individual hobbyist developers I have, I can almost count in one hand. (VSCodeVim being the most important one)
Now I compare this to my Neovim setup, and that one is basically running on charity from OSS developers.
I have completely opposite experience with [modern] Emacs. Of course, it wasn't smooth from the day one, but neither was my ride with different IDEs. Somehow, I keep coming back to Emacs because no IDE ever provided all the machinery I need to be productive. For me (and I suppose for many other people), Emacs is far more sweeter spot of an IDE than any other alternative.
I still use it, it is maintained and it is very good and fast, and that it didn't try to reinvent itself is a good thing for me. But it is not a full IDE (not Jetbrains), it didn't jump on the AI bandwagon (not Cursor), and it is not free (not VSCode), so it is not surprising that it lost some market share. But it is not dead.
Well, OK then. Back to Emacs I went.
As for people in general, safe bet in almost any topic is that most people won’t care. :) So yes most people use VSCode.
