If you want to do super big picture macrohistory, humans have really had three eras:
1) Hunting/gathering
2) Agriculture
3) Industrial.
To over-summarize, hunter-gatherers, with some exceptions in nutritionally dense areas were generally egalitarian. They had high childhood mortality and a fair bit of violence, but they lived longer lives than any time period before the Industrial era, and were health. In some cases we still haven’t caught up (for example, the width of hips of their women was wider than ours, and that correlates to health and easier childbith.)
Agriculture started out OK-ish for about 2,000 years, but the nature of agriculture creates private surpluses and allows for large elites. It’s easy to appropriate food and service from farmers, because they can’t move away and they can’t hide their take well (crops are harvested at known times, and about how much land produces is also known.) For the vast majority of the population, living in an agricultural civilization sucked. Yes, there were more of us, but we were sicker, died younger and more likely to have a nasty overlord. Violence decreased (though these figures are controversial), but that’s because the lords and masters don’t want other people killing.
Humans in this period were essentially domesticated, and there’s some reason to believe the process weeded out most people who naturally rebel against control. This is little different from how wolves became dogs, and just as degrading.
We know the industrial era, because we live in it, but I want to invite you take the long view: imagine it’s a 1,000 years from now. Or 5,000.
What the industrial age looks like when you zoom out is “the petrochemical age”. We figured out how to harness coal, gas and oil, added in a few other sources of energy, and became clever at hooking machines up to our power sources.
The problem is that in a period of less than 300 years we’ve burned up so many petrochems that we’re overheating the planet thru the mechanism of climate changes gases, and our population is well over the planet’s carrying capacity, leading to a crush in ecosystem diversity and the absolute number of animals, plants and insects.
Since ecosystems + climate are what make the planet habitable for humans, from the long point of view, all the industrial/petrochem era looks like is a massive orgy: a predator species which has overshot the world’s carrying capacity.
If we can’t transition to a technological way of supporting ourselves which doesn’t destroy the world’s carrying capacity, then all this period will be looked back on as is a blip: a brief period of species-wide stupidity, where we exploited technologies and powers we were too foolish and stupid to control the consequences of.
Progress isn’t automatic, and it isn’t one way. When you look at charts of health characteristics in the western world from the stone age, on, one culture stands out: Greek City States. They live longer than anyone else, they are healthier on multiple metrics, and their civilization is destroyed by the Romans, who don’t have nearly as good lives.
The same thing can happen to us. We are not sustainably transitioning to a new way of living. Even when we do some right things like electrification, we don’t build items to endure. We’re dumping valuable minerals into phones and cars and consumer goods we’ll throw out in 5 years or so, and we don’t have the resources to waste. We’ve done nothing to stop climate change. We’re over-fishing. Over 90% of the insects in multiple areas (perhaps world wide) are gone, as anyone over 50 or so can tell you. The birds are gone, too. The big animals. The wild areas. The coral reefs are dying. The Amazon is dying and now a net-emitter of carbon, not a sink.
In theory we could probably still fix this. The technology either exists or is with in sprint to do so, but it’s about more than technology: we’d have to change how we live. Give up our consumption based society; get rid of planned obsolesence and use the same items for decades. Ditch exurbs and suburbs almost entirely, and re-wild or make it so that people who want land have to live by the rule that their presence must increase biodiversity.
The changes are radical, and there is no sign of anyone in power taking them seriously. Instead we build more and more crap, pollute more and more, spew more and more gases into the atmosphere, and salivate over drilling for gas and oil in the arctic, even as we run down or pollute our aquifers.
Our technology was a test: we were given (or gave ourselves) great power, and our task was to use it to benefit ourselves in a way which was beneficial, or at least not catastrophic, for the rest of life on Earth (our ecosystem) and to not destroy a climate which is the only one human civilization has ever known.
We failed in this task, and so the Petrochemical Age is likely to just look like a blip. Perhaps a new technological civilization will arise from our ashes: but if it is to survive and prosper it will have to do what we didn’t and give at least as much back to nature as it takes out (and rather more, to fix the damage.)
As for us, it seems unlikely most of our civilization will make it. Doubtless hi-tech enclaves will continue to exist, but ecosystem collapse, water shortages and climate change make it unlikely our civilization as a whole will survive another century. It may not even make it 50 years.
And looked at from afar, it’ll be a 4 century mistake, in which some people lived very well, but the near permanent ability of Earth to support life was damaged, making every future human poorer in a very real sense.
