I use it. But honestly the reason why is because in 2005 or so I got a web job and my manager sat me down at a Solaris sunray running thr Java desktop environment (gnome) and told me to click on XEmacs to edit code.

Now I stay because lsp makes it good for every language and then org mode and tramp and babel and eshell are just game changers.

I don't see too many emacs users. My old director at Walmart Peter was one iirc.
