I think we'll see AI assist in the 80% of design work that is bland/generic and get out of the way for the other 20% that is interesting/obsessive/fun.
I think this is the same question of "Why isn't there a bar exam for medical doctors". "Being qualified" for software requires nothing less than hands-on training.
Until software moves to more apprenticeships/residencies, I'm afraid we stuck in this "infancy" of a field.
