Have you looked at all the video ? This talk is actually about children education ( to build a better future). But then he brings deatchcamps, his dentist not removing plastic protection often, francis bacon new science, aristotle not knowing the number of teeth of his own wife, brings some statistics in the middle about mental disorder, etc etc.

It may be human critical thinking, but then please it needs some structure and a feeling of progression in a reasonning, actually leading somewhere ( and if that something could be anything new, more than just « computers could be better learning device » that would actually help).
