I definitely still use Sublime. It's not my go-to for everything now, but my job has drifted in a way that means I don't DO those kinds of tasks that often anymore. For writing I've gravitated towards tools with better innate outlining and/or Markdown support (Obsidian); my work notes are still mostly in emacs/orgmode.
But if I need to open a big-ass text file, or process something in a pure text environment without anything helping me or trying to preserve formatting... yeah, it's probably still Sublime.
