Very good point. I strongly suspect as an individual's autodidactic capabilities increase, the need for highly-attuned teachers decreases, and by college-level academics MOOCs may be far more effective in that context. I think ironically however, that the need for high-attuned mentors comes up later, as the academics segues into field practice.
