SCUSKU•7h ago

It might not even be an apocalypse.
stego-tech•7h ago
It’s also worth noting that Strauss, Howe, and Turchin all repeatedly stress in their books that firm dates aren’t a guarantee, that sometimes the cycle doesn’t line up correctly (like the Civil War cycle), and that none of their words are meant to be taken as literal predications so much as cautious warnings that history often rhymes.

Having finished both The Fourth Turning and End Times recently, Strauss and Howe’s specific guesses as to what might fuel the next crisis are laughably off track even if their broad strokes still paint a compelling (and at times, frightening) picture, while Turchin feels more prescient in his observations.

Ultimately, though, Turchin has the better message: even when a crisis destroys an empire, the world continues onward. That gave me some bleak hope to hang onto.

Plenty happens, but:

1. Events, including big ones like 9/11, don't unfold like in the movies as even direct consequences are often far removed.

2. Pax Americana + Hypernormalization + Cheap Food + Digital Escapism = a drug which convinces its users of neverending stability and order.

Very disingenuous to put second-coming style prognostications from religious nutsos in the same list as people trying to use science, pattern analysis, or surveys of scholarly literature to identify when society will gradually break down from writing too many checks the environment or the economy can't cash.

citizenpaul•6h ago
What qualifies moving from "pending" state to "active". There seem to be many predictions at the bottom that are only a few years out that are not "active" Some are even end of year.

I could see why the ones with several hundred years deadline are "pending"

kej•6h ago
Pending means we haven't reached the start of the predicted time range for that event yet. If I predict a collapse in November of 2025, it would be pending for the rest of October, then active on November 1st until either the collapse happens and it becomes successful or December 1st arrives and it becomes failed.
wartywhoa23•6h ago
It can show 0 successful predictions all it wants, but we'd been through global lockdowns and forced vaccination, there's an ongoing war in Europe with casualties in hundreds of thousands on both sides, Gaza is being demolished by Israel, Internet as we knew it is about to turn into whitelisted fiberoptic/5G TV, surveillance is rampant, and the rise of the global technofascist police state as the public is being entertained by the clown shitshow of top level politicians is not obvious only to those who've been trying to save their sanity by remaining in denial.
jungturk•6h ago
Don't disagree with any of that, and I don't want to minimize the seriousness of the issues you've cited, but that kind of reinforces the implication of the scorecard?

People are persistently presented with perils (plagues, parasites, pollution, power-hungry politicians, propaganda, plutonium-powered projectiles, etc...) and humanity keeps finding a way through (though certainly at great personal and population-wide cost sometimes).

Some pretty serious chokepoints in the full history (including research suggesting that something reduced our ancestors numbers by ~99% a little under a million years ago) and yet this particular strain remains.

I've been in the "doomer" camp for over a decade and been surprised how many things I thought were far off in the future have come to fruition earlier.

But, the one thing I always find interesting, philosophically, about believing the world-as-we-know-it is coming to an end is that all of the things people are concerned about will happen no matter what.

Being afraid of the end of the world is ultimately being afraid that we will lose the things we have, that our work will be lost to time and history, that ultimately we will return to a void and all of "this" will have been for nothing.

However, all of that is true either way. You will lose everything you've ever loved over time in life, all the work you've done will be lost to time, in the end all of your efforts will be for nothing and even that won't matter.

The "end of the world" scares people because it forces them to discard the normal tools they use combat these many existential anxieties, but the world continuing to go on doesn't actually resolve any of those anxieties.

mfro•6h ago
'The world continuing to go on' is the status quo and has been for millenia at this point. Sure, the argument can be made that the world will end eventually, but if we do not have our reference timescale, what do we have? People aren't afraid that the world will eventually end (because 'eventually' should be thousands of years from now), people are afraid the world will end NOW, which does nullify your experience and efforts on the subjective human timescale. Life as we know it continuing to go on without ambiguity on our confidence to prevent world-ending events does resolve those anxieties.

I am reminded of Roy Scranton's essay Learning How to Die in the Anthropocene [1]

> I found my way forward through an 18th-century Samurai manual, Yamamoto Tsunetomo’s “Hagakure,” which commanded: “Meditation on inevitable death should be performed daily.” Instead of fearing my end, I owned it. Every morning, after doing maintenance on my Humvee, I’d imagine getting blown up by an I.E.D., shot by a sniper, burned to death, run over by a tank, torn apart by dogs, captured and beheaded, and succumbing to dysentery. Then, before we rolled out through the gate, I’d tell myself that I didn’t need to worry, because I was already dead. The only thing that mattered was that I did my best to make sure everyone else came back alive. “If by setting one’s heart right every morning and evening, one is able to live as though his body were already dead,” wrote Tsunetomo, “he gains freedom in the Way.”

For me the problem is managing the transition minimizing unnecessary suffering.

The world is inevitably going to end, our work isn't going to be forever preserved into the future and there will be no "end of history" until there are living humans.

The thing is that the world can end in many ways. My world can end in many ways. I'd rather pass on with a clear consciousness, with my faculties preserved more or less, and with a legacy of having at least tried to make the lives of other that tiny bit better, so I'm aware if I'm not vigilant I can spend my final days suffering from an avoidable disease or accident or regretting I wasted my life chasing a better tomorrow that never came while neglecting what I already have today.

This is virtually the same for all society. It's going to fade into oblivion, but it matters a great deal that the process is as gentle as possible for everyone involved.

People like Ray Kurzweil, Jürgen Schmidhuber, Leopold Aschenbrenner, Paul Christiano see a pathway out of this inevitability through technological singularity. In their vision humans are a seed to something greater, something noticeable on cosmic scales. In their vision, like early humans who emerged on the other end of genetic bottlenecks, today's humans will have a disproportionate effect on the future. According to the current models of cosmology heat death of universe in still inevitability but that's on a completely different timescale than human life.
the_af•3h ago
Please don't take this to be dismissive of your comment, because that's not my intention, but...

I think people like Ray Kurzweil are essentially religious. Instead of a messiah and heaven, they think of salvation in terms of a singularity, immortality, or a way of ascension. It feels very religious to me, and as such, detached from reality and physical possibilities.

A bit in the doomer camp, and what worries me the most are the lifestyle changes needed to not fuck up the climate in the next few hundreds years. I believe I heard that we should slash 7/8th of our emissions (as individuals living a modern lifestyle) to keep the wet bulb temperature in check worldwide by the end of the century. This is, in my opinion, a target that we'll surely miss and it won't be nice.

Europe is already struggling with few millions people trying to enter over several years. I can't imagine what happens when large parts of India/Pakistan/Bangladesh become literally deadly during the hot season. That would displace ~1B people basically at once (if you stay and you don't have Air Conditioning you die). The following turmoil will be like nothing we ever saw before as a species (IMHO).

ipaddr•4h ago

_carbyau_•4h ago
As a society if we care about our fellow humans - generally seen as a virtue to have - then we need to reduce our emissions etc etc.

As a rat race where the competition is between humans then rich people have a comparative advantage regarding how to survive the ravages.

So the future is less about avoiding climate catastrophe completely - that won't happen when the rich and powerful don't care.

The future is about surviving the issues until enough people die that emissions takes care of itself.

Either a lot of people die thus reducing emissions, or specific groups die thus reducing the capability to generate emissions on behalf of others. Or maybe enough tragedies happen that moral conscience does hold sway. Likely a combination of the above.

For supporting the continuation of my genes, maybe I should invest in property in Siberia/Alaska/Canada/Greenland/etc etc.

That's why global nuclear disarmament seems only slightly more plausible to me than (e.g.) global artillery disarmament.

The Limits to Growth book is an interesting read. To quote Box, "All models are wrong, but some are useful". I wouldn't take the dates-ranges estimated from the modelling that seriously, but the modelling assumptions are worth reading about and reflecting on. The overall modelling and dynamics seem pretty plausible to me.

From memory, the rough argument was that society depends upon input flows of energy, resources (metals etc) and food. Society needs to allocate resources and energy to extract these inputs. Energy sources such as fossil fuel reserves are finite stocks, some are cheap to extract (high energy return on energy invested). Over time we consume and deplete the high EROEI reserves and have to move on to consuming the lower EROEI reserves. This means that the fraction of energy society needs to allocate for energy extraction increases over time, so there's less energy for other uses. Similarly, we deplete the cheap to extract stocks of metal required to build and maintain industry, leaving stocks that require higher inputs of metal and energy to extract. Similarly for agricultural yields, as we mine and deplete accumulated stocks of nutrients out of the soil.

The business as usual scenario leading to "overshoot and collapse" behaviour is that we have increasing population, increasing industrial capital and increasing demands for energy, food and resource inputs, while the fraction of energy and resources that need to be allocated to energy, resource and food production grows over time. The fraction of remaining surplus energy and resources that can be allocated to things like education, healthcare, research, art decreases over time. At some point the growing fraction of energy and resources that needs to be allocated to energy and resource extraction becomes so large vs the existing population and industrial base that there simply isn't enough surplus to maintain healthcare, education, research, etc at the same level.

The "Overshoot and collapse" dynamic describes stocks of population, industry etc growing to peaks well beyond sustainable levels before the above dynamics catch up and cause them to rapidly decline.

The researchers did a bunch of modelling of alternative scenarios, exploring how to avoid these "Overshoot and collapse" dynamics.

kulahan•5h ago
One mildly interesting fact that MANY Christians get wrong:

There is no lead-up to the apocalypse. The Messiah will return "like a thief in the night" and "nobody, except my Father, knows the hour of my return" (I probably butchered those two quotes). Either way, the Bible is pretty clear (as was Jesus): there will be zero indication the apocalypse is coming. None. It'll just... start.

If someone plans to, they should first read Revelation 22:18–19.

Understandable, but citing the Bible is fairly important in theology, though it should be done within context.

Sure, Judaism was word of mouth a long time, and that’s great. I personally can’t remember much, so I think referencing text is fine.

See, that's when you use literal reading. "I'm not adding anything to the text, I'm just interpreting it."

Ezekiel is clearly about events in our past, though.

>Understandable, but citing the Bible is fairly important in theology, though it should be done within context.

For anyone curious about academic studies of historical societal collapses, check out Joseph Tainter [1]

> As described in Tainter's Collapse of Complex Societies, societies become more complex as they try to solve problems. [...] Such complexity requires a substantial "energy" subsidy (meaning the consumption of resources, or other forms of wealth).

> When a society confronts a "problem," such as a shortage of energy, or difficulty in gaining access to it, it tends to create new layers of bureaucracy, infrastructure, or social class to address the challenge. Tainter, who first identifies seventeen examples of rapid collapse of societies, applies his model to three case studies: The Western Roman Empire, the Maya civilization, and the Chaco culture.

> For example, as Roman agricultural output slowly declined and population increased, per-capita energy availability dropped. The Romans "solved" this problem by conquering their neighbours to appropriate their energy surpluses (as metals, grain, slaves, other materials of value). However, as the Empire grew, the cost of maintaining communications, garrisons, civil government, etc. grew with it. Eventually, this cost grew so great that any new challenges such as invasions and crop failures could not be solved by the acquisition of more territory. [...]

> It is often assumed that the collapse of the western Roman Empire was a catastrophe for everyone involved. Tainter points out that it can be seen as a very rational preference of individuals at the time, many of whom were actually better off. Tainter notes that in the west, local populations in many cases greeted the barbarians as liberators.

Was the Bronze Age Collapse a doomsday event? Mount Toba eruption? I think they were.

I'm not saying anyone predicted those or something. It's just that the notion of doomsday is quite vague.

I'm trying to broaden some notions here. Prediction might not be exactly absolute prediction, and doomsday might not be exactly absolute doomsday.

Perhaps some great threats were averted precisely because someone predicted them (for example, the great leaded gasoline poisoning).
