A dozen years ago or there about, Bill Gates became worried about Climate Change and gave a TED talk on what the world had to do to save us from extinction. In that presentation Gates stated that one of the variables in his equation had to go to zero to stop Carbon Dioxide from killing all of us. Now keep in mind that Gates does not have any degrees and knows little about anything but making money with software. We do however recognize that he was very good at that but we must also understand that he had no formal training or studies in anything else.
Gates’ vision is a world with less than a billion people and probably closer to 500 million. This world will be very clean and use only solar PV or Wind to power this Utopian Dream. Everything will be perfect and safe for those that reside in that world. Dreams of that kind are neither practical nor doable but that never stops those that have these visions: like Karl Marx who also had a vision of a perfect world Marxism. Unfortunately that vision brought us WW I, WW II and the cold war and hundreds of millions of dead people, and Marxism has still not been eliminate as an evil system.
