All of these are missing the point imo. The biggest advantage of modern IDE is the ease in trying new plugins and functionalities. Everything is a menu away, and fuzzy searching makes it easy to find out commands and learn their shortcuts. This whole process just doesn’t exist in emacs. To get a plugin, it’s a huge step (setting up custom elisp to get melpa) and then it’s a huge learning curve just to try a plugin.
I like that kind of stability, makes it possible to move my focus away from the editor, towards the problems I'm trying to solve.
