"So, humans. Only sapients on our world - this is not essential to the not-suckery, just an incidental feature of the situation. They start out as just really intelligent biologically successful apes with absurd brain capacity, a lot of which is used for intergenerationally transmissible firmware and anomalously abstract reasoning. But their lives, modulo complexity of politics and techniques, are still not hugely different from chimpanzee lives - stay fed, stay warm, evade danger, evade illness, evade ostracism, have kids, help the next generation."
"Then one guy - be it regretted that history lost the many true names of the people who were this one guy - was like, 'You know how plants just keep growing over and over again, under the right conditions? Maybe we could just reliably create those conditions and then we'd have a predictable harvest and we wouldn't have to worry about wandering around for food so much anymore.' As it always is, it was way harder than it sounded, but that one guy - bless his many instances - was so right that most of the holdout bands who didn't adopt farming initially were eventually physically displaced by those who did. Those who weren't physically displaced, were out-reproduced and overshadowed. It turned out there was a lot more to farming than just allowing your little band to stay in one place. You could support quadratically more people in the same land area by optimizing both the growing conditions and the heredity of the crop plants themselves."
"Agriculture was more time-intensive per calorie than hunting-gathering for a while, and settlements had people who didn't know each other by name, and that created new problems that had to be solved with new institutions of arbitration, but if the effect of settlement was really overall bad for the people in it, they would genuinely have just gone back to living the other way. If you live in a settlement, even if more of your hours are nominally eaten up by food production than would have been the case for your hunter-gatherer ancestors, the rest of your hours are entirely, predictably, structuredly free. Want to get really good at just making shovels? Plows? You can do that, in those extra hours, without worrying that it'll end up advantaging you literally not at all in the end, because hey, your city will predictably be here, and predictably need these things, basically, regardless of what happens in the next few years. People had a sturdier social foundation on which to build things, and they did. And so there were better shovels, better plows. Eventually, techniques for making better metal and better stone. Preparing food faster, washing clothes faster, making cheaper paper . . . and each of those industries became a social-island-of-stability-and-predictability unto itself, a platform for further optimization by experts within it who could then see something to gain thereby."
"Your world is already to that point, I know. My meaning is - people in your world don't have enough choices, by a long shot, as to what they'll do with their lives - which of course is dependent on who they can associate with, because anything you produce for money must be sold to some reliable consumer who understands that, be that the market or your boss - but they have vastly more such choices than their ancestors who lived in the first settlements, who had vastly more such choices than early humans who scraped by in bands of 50 people - assuming your lineage's group size wasn't too different from our own."
"Take that process, of settlement, of increasing industry, that your world has already undergone, and extrapolate it, and it turns out that within a few thousand or hundred years, you get almost-costless universal food, almost-costless universal housing, with plumbing and effortless temperature control and light at night, cheap clothes and transportation and childcare and info-recording-storage-and-transmission, cheap easy-to-use self-defense weaponry so even the physically weakest people don't have to worry about meeting overwhelming force, and - it looks like, pretty soon - immortality."
"But the structure underlying all that technology, the essential thing to why life doesn't suck here nearly so much anymore - is that even the least trainable people have multiple bosses to choose from. Our least-skilled have thousands of of times more options for bosses, than when our world was around your world's level of development, if I'm reckoning right."
"If you run a factory, and your employees have other factories they can go work at instead, you can't be a tyrant even to your dumbest employees, or they'll take that choice - at a wage cut, even - and you'll be left at a disadvantage and, in the limit, run out of business."
"Thus, the future dissolves tyranny. Not perfectly, yet. Wherever there's a monopoly, because somebody's figured out how to do something new, little tiny tyranny-bubbles still happen. The future future is expected to be better. We're working on it."
