As a concrete example: I'm racking my brain trying to think of any instances of a working realtime whole-desktop translation overlay application, and I don't think such a thing exists.
Translators for specific chunks of the screen, yes. Selectable translators, sure. Translators you can configure to work with one application at a time.
But rewriting all text in the entire windowing environment? While preserving selection, copying, and editing? Without hooks to the underlying apps? Functionally preposterous as a proposition.
