You can exit Emacs by clicking a button, by making a mouse gesture, by telling it via voice command, by key-press, by modal key-chord sequence, by writing into a file, by selecting a menu item, by directly evaling (kill-emacs) command, by cookie in a file you merely visit, by a keyboard macro replayed from a register, by an abbrev whose expansion hook quits, by evaling an Org-mode source block, via a timer, via built-in solar and lunar calendars, by a shell command run inside Emacs that kills its own parent, by SIGTERM or SIGHUP from outside, by closing the last frame under the WM, by an LLM agent with an eval tool, and by pulling the power cord.
"I don't think" is never a good argument for making wide claims about anything.
