One of the most insidious and dangerous assumptions we have is the silly idea that human history has a direction. That in some meaningful way, life in the 21st century is fundamentally different (even "better") than life in, say, the 14th century, or the 21st century BCE for that matter. That human events follow a more or less predictable (at least in hindsight) trajectory from "primitive" to "advanced", and that it does this because of some sort of natural law that governs all kinds of progress.
This idea is pure bunk, and should be stamped out with extreme prejudice wherever you see it. It is the kernel at the center of the centrist's inaction in the face of injustice, the unfounded presupposition behind violent wars of "regime change" and "nation building", and the morally vacant justification for colonialist thinking. It is the reason we are taught that the evils of slavery and genocide are "in the past" while the forces that drive them simmer in communities around the world.
History has no arc. It is not a story about a protagonist species who learn and grow. It has never been guaranteed that tomorrow will be more just for you than today, or that the next century will bring more opportunity for your descendants than the last one had for your ancestors. This should be plain to see as we watch the entire allegedly "free" world slip farther every day into the same patterns of mistakes and collapse that have recurred time and again since anyone bothered to remember anything.
Even when disaster is averted, for all our apparent progress we have never actually made a difference in what it means to be human. Sure, we have the power to blow up the planet, the power to fling ourselves uselessly into orbit, the power to talk to each other across insurmountable distances. But so what if we can do all this, but give up the ability to feed our children, or the time to appreciate a sunset once in a while, or the courage to speak to our own neighbors? What have we gained, exactly, and why do we imagine that to be "progress"?
