Text-based interface with fuzzy contextual autocomplete is the best of both worlds. Think of an IDE's autocomplete popups, but for terminal commands. Or how the Command Palette in means I almost never have to memorise where some obscure setting because I can just type the first few letters and find it as a top match. No such UI exists for terminal emulators because they don't work that way, but I'm convinced if someone made a program entirely around text with autocomplete it would be just as accessible to non-technical people.
