Which then gets you pilots frobbing the autoland selector, not getting the mode right - and now what, if you have zero practice, having scripted yourself out of it? Now you fly the plane into the runway: https://en.wikipedia.org/wiki/Asiana_Airlines_Flight_214

There is a (prevalent) happy path where autopilot and autoland can get you the whole illusion "but the plane flies itself" - but the whole system is built around humans catching and handling all and any exceptions.
