I spoke at the Poptech 2012 conference in Camden Maine. I spoke about my pyramid “theory”, why the pyramids in Egypt are three? I write more about that in my book Dreamland. How we become addicted to destructive industries and stupid ideas. How can we explain how scientists from the top universities of the world can see that we have gone too far already in our stress on the planet while people from the same institutions produce people that see the plan to triple global production of everything in the next 20 years.
