There's also the validity of learning methods, despite what studies may claim, there's no scientific "grand theory of meta-learning", and if ideas are misapplied/misused there's a risk of falling into scientism, which would be just as harmful as economically driven credentialism. At worst it is just the austerity version of education—learn it yourself because we can't afford the school resources to teach/coach/nurture subjects.
