In aeons to come, I think historians from whatever many species humans have become will be fascinated by our era. I personally think we monsterously privileged to be alive right now. We, as a species, have entered our adolescence.
For most of our past, our ancestors have lived as ignorant children in the garden of Eden. We were mere intelligent animals, living out our evolutionary instincts in an era when they served us well. Unremarkable beside our countless other cousins in our biosphere.
Since about the end of the middle ages, we have entered a scientific revolution that has wrought huge changes in our species. I think future historians will look back on the era ca. 1500-2500? as the time when we ate from the tree of knowledge for our species. It is us, right now, who must do this. There is so much we must overcome. Now that we have the power to destroy ourselves, humans have never and will never again be as painfully vulnerable. Will we survive another 500 years of natural disasters and weapons of mass destruction? What is "The Great Filter" of civilizations, and will we survive it? Our evolutionary predispositions, like social divisiveness, religion, aggression etc are a continual source of problems. Might they go away as our collective wealth and knowledge increases, or may we have to eliminate them through genetic engineering? We do know there is currently practically no evolutionary pressure on humans, and that may be bad for our future. What's very interesting is that humanity has never been as interdependent and collectivized as it is now, and after this era, will never again be. I pity our libertarians. Perhaps they will be the first to abandon us and colonize some small objects in our solar system where we will never find them. If the colonization of the Americas is anything to go by, it will be the groups with non-mainstream political and religious beliefs who lead the way and have least attachment to home.
If we are successful in maturing, the tiny little organism we call Earth, for whom we act as gonads and central nervous system, will spread its seed throughout the cosmos. It is the first of a species which will someday - quite literally - be as numerous as the stars of the sky. Humanity will transition from a fearful, instinctual childhood when we were unremarkable beside our animal cousins, into an adult civilization that can will inherit the cosmos. What do you think?
