I am reminded of the scene in Idiocracy[1] where we see the receptionist picking conditions from a board containing a few dozen colorful icons. There certainly is a sense in which you could abstract e.g. medical diagnostics in a way that makes illiterate people better at getting an LLM to give advice to a patient. But to go back to my 3-part statement: do people who can't organize and express their thoughts really deserve to be in charge of your medical diagnosis?
Or in other words, are UX designers catering to an audience that ought to not exist in the first place.
