In uni, my friends used the phrase “simple solutions for complex times” as an insult for political ideas. Cutting the Gordian Knot only works well if your father spent half his life perfecting a new military doctrine for you.

Yes, it will surely all end in calamity, whether anyone here experiences it themselves or not. Humans have a major (among many) flaw, in the nasty tendency to believe they not only have a sufficient understanding of sufficient enough things, but that they also know the effects their perceived perfect choices and actions will have on such a complex system. Many religions have stories capturing this folly, the most famous possibly being the Tower of Babel, which were are furiously building in spite of what many humans call God, while others believe they have no more need for a God greater than themselves.
