Emacs is malleable, but it shows that it comes from a pre-CUA era. IMO, they should just drop the existing UI preset into a "legacy UX" package that old-timers can keep, and come up with a new preset that will be familiar to users of post-Win95 machines.

IntelliJ does this right. You are dropped into a brand-new, complicated editor, but the basics like the arrow keys, Ctrl+C/Ctrl+V, ctrl+arrow key movements, menus and lots of other bits are already familiar to you. You may remap the editor in any way you want, but you are likely to override a few presets and get on with your day, than rewire the entire thing.
