Emacs seems to be in the same position as LaTeX: Outdated paradigms that would probably need an entire redesign from the ground up to start "making sense" in the modern world. This starts with (nowadays) non-conformant shortcuts, includes window/buffer management (the terminology alone is archaic: panes are windows and windows are frames), and ends with elisp, which even Lisp programmers themselves rebuke.
But such a do-over is impossible in both LaTeX and emacs, since that would also mean throwing all the thousands (ten thousands?) packages--and lots of core functionality--away. Stuff that has accumulated for many decades and that is the reason why we're sticking with it: Everything else feels very limited in comparison.
And it's not just the "big" things. When I want to sort a few lines in a region and immediately discover that I can just call "sort-lines", because of course I can, I know that I'm not going to bother waiting for some other editor to catch up in all those little things.
Admittedly, I haven't tried modern distributions like spacemacs and DOOM Emacs, but it's a bit hard for me to imagine that you won't need to come face to face with "emacsism" at some time.
