His talk is exactly what he talks about: he presents ideas at a level of understanding of those listening to him. Instead of being scientific or philosophic, he gives interesting examples such that people immediately get it.

Alan's all about looking at the big picture and not getting lost in irrelevant details. He tries to get his point across right away by showing how NIMH is so focused on canonical mental health problems that they don't think about where these problems come from, nor about even bigger mental "problems"(such as the 99,77% if you watched through the talk) and what mental means in the first place.

He may not know how to fix healthcare, but he shows what is necessary for us to think about if we ever want problems to be solved. He then follows with examples from the areas he's more familiar with, namely tech and education, to show how to get to solutions without brute force.

Human critical thinking at its very best.
