I only use a handful of packages, a smidge of Org mode, minimal customisation, & run Emacs in the terminal, so switching to something more modern should surely give me everything I need & many more features in spades. But nothing else scratches the itch despite my best efforts to move to something else.
Perhaps for me Emacs is like an old pair of slippers: comfy, familiar, does what I need it to without fuss. I can't say whether it's a good choice for anyone else, but this grey beard engineer likes it.
