Having addressed humanity's future here — https://steemit.com/energy/@freeradical/you-want-100-solar-energy-it-s-coming-and-we-re-going — I have to say that I very much agree with the creator of this short video — http://www.kurzweilai.net/we-are-probably-one-of-the-last-generations-of-homo-sapiens-yuval-noah-harari?utm_source=KurzweilAI+Daily+Newsletter&utm_campaign=defdf609f1-UA-946742-1&utm_medium=email&utm_term=0_6de721fb33-defdf609f1-282113745 — as humanity will surely face extinction if it doesn't evolve beyond its present state through intelligent design.
After all, we're facing extinction at this very moment, what with enough nuclear weapons to wipe out our and god-knows-how-many other species at the press of a button.
Why?
Because while we are endowed with the faculty of reason, this does not ipso facto make us rational. For as science fiction writer Robert Heinlein wrote over 60 years ago, "Man is not a rational animal; he is a rationalizing animal." And because of this — because we are driven more by emotion than by reason — we are capable of justifying, and therefore of doing, anything, no matter how heinous. Surely human history and current events bear this out, not least by the existence of the entity that designed and built nuclear weapons — the state — which is nothing more than institutionalized aggression: the initiation of force and the threat thereof.
Indeed, the state claims a territorial monopoly on the initiation of force, in keeping with Mao's brutally honest dictum: "Political power grows out of the barrel of a gun." Not just communist political power, mind you, or socialist political power, or fascist political power but all political power. Thus does the legalization of the immoral lie at the heart of what rules the human world. For as theft is considered immoral except as the state commits it, it is clear that those who are thereby "licensed to steal" are accordingly "licensed to kill.*
Thus does irrationality rule our world, and thus will it culminate, if not in nuclear armageddon, then in our trailing, Neanderthal-like, into an evolutionary dead-end. Which is why we have to intelligently design our ourselves beyond humanity as we know it. That is, we must merge with our machines so as to evolve into truly rational beings, beings driven first and foremost by reason, so that our emotional lives can extend beyond the "getting and spending" by which we "lay waste our powers — https://www.poetryfoundation.org/poems-and-poets/poems/detail/45564 — mindful that we have barely crossed the first field of our fantastic voyage.
