I want to study this a lot more. Some years ago I read that Earth can only support one billion humans and not have permanent impact on the ecosystem.  It is a fact that we are on the brink of major breakthroughs in genetic engineering and artificial intelligence. If the human species is to survive then different models and paradigms must be found.  The entire world must unite under some one government. Warfare must cease and (in my view which many abhor) warfare must cease even if it means using weapons of mass destruction to permanently alter the ethnic and cultural landscape of the world on a grand scale.  We must reduce human population to one billion or less and live in a fashion which makes minimum impact upon the ecosystem and non-renewable resources. If possible a new strain of humans must be genetically engineered in which irrational passions leading to violence are minimized or eliminated. The paradigm of the citizen will not be that of a farmer nor of a factory worker. Robots will perform much of the work. Artificial Intelligence will be a tool to do our thinking and perhaps our governance for us. Look at China's population problem and the one child policy where not enough females are born. As the world changes so freedoms change and are redefined. In the Wild West everyone carried a gun out of necessity. In our modern cities only few carry guns. In primitive societies a person might take several spouses and have as many children as possible.  Live on Earth only has something like 500,000 years before the sun, as a white dwarf, grows in size and becomes too hot. People like Steven Hawking are trying to urge people to think toward that future but the majority are only moved by personal greed and fear and very short term goals. Most people say "what do I care about 500,000 years from now?"  When the Earth becomes uninhabitable then Plato, Shakespeare, Euclid... all human culture and history becomes meaningless.
