I agree GA over-promises jobs to unqualified students with no relatable, professional experience.
However, I do think anyone can do “UX” because they will have to. As more and more companies are adopting lean methodology practices, you end up having whole teams rooted in UX principles. Now I agree specialists (i.e. interaction designers) need more formal training and that you can’t just take a course and become a UX expert overnight. But in my opinion the traditional UX designer role — while hot right now — will die eventually, and cross functional teams will practice design thinking together with designers teaching the way. As you say, “Alternate perspectives allow for more diverse and original thinking.”
