If we all like play, or tinkering as he puts it, then why is there anti-intellectualism? Surely knowledge is the most interesting tinkering and perhaps infinite. I can not imagine anything more creative than two ancient people sitting there and thinking, hmm we do need to keep a record of how much crop we are making so that we can be prepared for natural disasters and not starve. I've noticed that usually in the summer we do good, but in winter not so good, how much do we need to survive winter? And then sitting there and thinking hmm well I suppose if I make a line on this thing that means x amount, two lines mean well x amount. Basically they are both agreeing on a communicating system through symbols. If that is tinkering, then what is creativity? Is creativity imagining what alien life looks like? Or is that tinkering? Is perhaps creativity the synthesis of many tinkering? I simply don't get it, but then the guy studies pseudo-science? It seems he is merely speculating and very subjective. What do I mean by subjective? Well subjectivity is thinking of what creativity could be. When one indulges in subjectivity they start making their own rules, they start fantasising and lose track of reality. In my opinion, that is what this guy is doing.
