The Oryx and Crake idea has been discussed seriously by Nick Bostrom. One thing to keep in mind is that for some metals things will be easier the second time around. The really prominent example is aluminum. It takes a lot of technology and infrastructure to refine aluminum (for most of the 19th century its price rivaled or exceeded that of gold). But, aluminum once it has been purified is really easy to work with. So one would have all sorts of aluminum just left around ready to use. Nuclear war makes that situation slightly worse because a lot of the aluminum will now be in radioactive cities. But overall, you’ll still have easily accessible quantities of a light, strong metal that no one in the middle ages had anything like.

(And aluminum is nice, but compared to ‘all oil everywhere being inaccessible except with a highly developed oil industry with centuries of refinement’...)
He mentions it www.nickbostrom.com/existential/risks.html. I think he has mentioned before that this is an aspect of existential risk that should be more closely evaluated and I think he’s briefly talked about it in other locations but I don’t have a citation.
Re: Aluminum, yes true, but don’t underestimate the helpfulness of having a really light and strong metal. Much of modern technology depends on that. And aluminum isn’t the only example of such a substance which will be easier to work with now that it has been refined. Titanium falls into a similar category. Both of them can be worked with at temperatures one can reach using coal.
Re: Aluminum, yes true, but don’t underestimate the helpfulness of having a really light and strong metal. Much of modern technology depends on that.
I ask because a lot of that modern technology seems predicated on cheap oil and all its derivatives like plastic or lubricants etc., such that aluminum is only a small benefit and nowhere even close to a bit of oil.
What’s the signal use of aluminum? Airplanes, but how are you going to economically power aluminum-built airplanes? Or skyscapers—but what’s the point of such dense expensive buildings if you are in an Industrial Revolution which is stalling out because the forests have been burned, the easy coal mined out, and oil completely unavailable? (Checking Wikipedia for aluminum, the lede highlights… ‘aerospace’ and ‘transportation’. And a lot of the other cited uses seem like they have viable alternatives, like copper—also available easily in the corpses of cities.)
A old comment of mine that seems somewhat relevant:
If a form of civilization based on agriculture is maintained after the technological fallback the next time around it seems plausible that we may also have a higher IQ and be generally better adapted to life in mass society. Human brains are pretty good at finding substitute resources.
Good observation that easily accessible energy is what makes technological machine based civilizations go. Speaking of which in the long term there would still be wood to burn, wind and water power, animal and human muscles. Also remember you can use selective breeding to make animals (and plants) better suited to human purposes.
Much better.
Maybe no industrial revolution, but at the very least given enough time… Also there is still coal, lots of coal, much of it hard to reach though.
If the human brains adapted that much genetically during the existing relatively fast ramping up of civilization, powered by cheap accessible energy sources, then it can unadapt in the event of collapse and subsequent slower ramp up, starved of cheap energy.
Human brains are pretty good at finding substitute resources.
We demonstrably are not pretty good at finding substitutes! Look at how well the existing highly experienced and technically sophisticated civilization has done at the task!

Cheap energy had very little to do with our massive changes. We are talking about consistent trend of people getting more adapted to civilization from the Neolithic through the Iron age and up until the 19th century. Freeze technology in any point between, humans would keep adapting to that level. And as long as populations continued to rise and new long distance trade links where being established, according to the 10k explosion hypothesis, faster. But I see your point, eventually as humans reached a new equilibrium and became decently adpated to life in static civilization and since there wouldn’t be a lot of change, intelligence may no longer be needed for stuff like farming, human evolution would start slowing down and veering into odd directions. I’m just not sure this [stagnant civ] would actually happen given the absence of say fossil fuels.
Arguably genes for high IQ became maladaptive basically at the same time when we got cheap energy and launched the industrial revolution. Sure there is the possibility that evolution goes ahead and changes us into something like farming, herding mammalian ants in the absence of cheap energy, but why is this so much more likley than say the idiocracy scenario of Azatoth doing horrible things to us in the presence of cheap energy? (depending on how one interprets history we may have evidence in favour of both btw)

On a time-scale of what, a century? In the absence of oil and coal I can’t imagine say 18th century European civilization stagnating on a time scale of millennia. These are cosmic eye blinks. Canals, wind-power and watermills had already basically created a mini industrial revolution in some places. I also can’t imagine say Aztec civilization stagnating in the absence of easily obtainable gold or copper.
On the grand scale, over time carrying capacities will generally rise as the crops and animals used are improved, people will get better at living in cities, merchant and priestly casts will keep getting smarter, farmers and herders will keep getting more resistant to infectious diseases and better adapted to their diets. And this should accelerate as long as population keeps getting larger.
Writing will be developed and continental scale empires may rise, if no earlier (because of say lack of iron) then when horse/camel/animal X riding hordes start extracting tribute from cities, or very very virulent religious memeplexes arise. The Mongolian peace and the Arab golden age where basically what happens when you tap into and connect a whole bunch of lands with differing intellectual traditions and make trade safe between them.
Eventually civilization will spread to harsh places like say parts Africa or Siberia where gold, silver, gems and even iron are still to be found. If scrap metals have been something known for millennia, and have probably become very high status items, how long before these smarter, perhaps more profit minded humans (at least their merchant caste) don’t eventually find a way to smelt them?
And you still have human selecting animals and plants. Combine this with an 19th or even 18th century of knowledge of heredity and you will be able to do really amazing things with domesticated animals on time scales of millennia. I wouldn’t put things like dogs breeds that specialize in sniffing out cancer, or parrots that are very very good at simple arithmetic and can be trained to communicate this beyond such a civilization. Not to mention all manners of beasts of burden or very fast birds with very good sense of direction that deliver messages across vast distances. And remember like dogs have been all these animals would basically be developing a human friendly user interface (behaviour a very simple understanding of how humans behave) over time. All of these examples are things that have sort of been done with animals, but we barley got started on before they became obsolete. Remember given enough time speciation would have occured between the breeds. What exactly are the limits?
Even places where not many animals where available for this such as the Americas, things like guinea pigs where domesticated. As long as you have at least one domesticated mammal or perhaps bird, your options are huge on the time-scale of a few thousand years (thing for a second of how dogs in various environments and of differing breeds have been used for everything from food to source of energy for transportation). So the process could easily eventually get started and I think once it does sooner or later, given writing and decent IQs, the knowledge of heredity will follow.

Carrying capacities may increase, but so what? You don’t see a whole lot of innovation out of Africa. Per capita is what matters, and per capita there is no long-term upwards trend. To quote Clark’s Farewell to Alms:
The wage quotes from 1780–1800 do seem to confirm that technological sophistication is not the determinant of wages. English wages, for example, are above average in the table, but not any higher than for such technological backwaters of 1800 as Istanbul, Cairo, and Warsaw.7 English wages in 1800 on average were about the same as those for ancient Babylon and Assyria, despite the great technological gains of the intervening thousands of years.

I also can’t imagine say Aztec civilization stagnating in the absence of easily obtainable gold or copper.
I disagree. 18th century Europe (by which I mean, of course, England, as the starter of the Industrial Revolution) was already dependent on non-renewable energy, and had been since roughly the late 1650s. Look at the charts in http://www.voxeu.org/index.php?q=node/6781 and notice where ‘coal’ exceeds firewood+water+other-renewables. (Firewood began falling in absolute terms; Easter Island comes to mind.)
I just realized we may be arguing about different things. I tought we where arguing about technologically progressing civilization that eventually leads to an intelligence explosion or life leaving Earth, while you may have thought we where arguing about escaping the Malthusian trap and increasing average living standards beyond sustenance.
Carrying capacities may increase, but so what? You don’t see a whole lot of innovation out of Africa. Per capita is what matters, and per capita there is no long-term upwards trend. To quote Clark’s Farewell to Alms:
Carrying capacities matter because according to the 10k model, larger populations in novel environment > faster biological evolution.
More people > more brains > bigger economy
And this should accelerate as long as population keeps getting larger.
I was referring to the speed of their adaptation.
Carrying capacities may increase, but so what? You don’t see a whole lot of innovation out of Africa.
Don’t see why Africa matters here. India and China created plenty of innovation. Higher IQ in the priestly and merchant classes will drive technological, scientific and memetic innovation. It will not be as explosive as the historic development of European civilization, but then again that’s pretty anomalous.
You say we aren’t good at finding substitute resources. This may be so.
In the absence of civilization bigger brains where a robust trend among hominids for millions of years. Bigger can be better when it comes to smarts.
And the whole idea of transhuman intelligences being so dangerous is that they are so because intelligence is overpowered in our universe. Would you feel safe dumping say an AI that was quite a bit beyond genius level on a resource starved rock (if stripped of all knowledge beyond that of stone age humans)?
And were you aware that your trend broke down 30,000 years ago, and the brain has shrunk?
Since the Late Pleistocene (approximately 30,000 years ago), human brain size decreased by approximately 10%; yet again, this decrease was paralleled by a decrease in body size
And were you aware that your trend broke down 30,000 years ago, and the brain has shrunk?
Yes. (“Dataset: all measurments of moninin cranial capcity available in the literature as of September 2000, for skulls older than 10,000 years old”).
Bigger can be better when it comes to smarts.
It was part of a overall argument that humans have probably been getting smarter for the past few million years. And that this trend had nothing to do with the availability of fossil fuels or iron until perhaps very recently. It seems likely that this would have continued in their absence. And it seems likley that bigger brains would translate into better tools and more complex social organisation as they tended to have in eons past.
I think it would basically fill the role of mithril. Neat very very expensive weapons/armour held as a royal treasure. A status symbol far too valuable to actually be used. With the occasional exception (radioactive hobbit stumbling into some in the swamps of N’ork).
Well, if one was using it for armor it wouldn’t be that hard to get a lot from the old cans and cars lying around. And the melting point isn’t that high. So it might actually be a common form of armor.
The Oryx and Crake idea has been discussed seriously by Nick Bostrom. One thing to keep in mind is that for some metals things will be easier the second time around.

The additional marginal value of human-architectured intelligence is questionable outside of a modern context. See http://www.gwern.net/Drug%20heuristics#modafinil

“Evolution of the human brain: is bigger better?” (this doesn’t include the bigger-brained Neanderthals either)

Accessible, sure, but what can you do with it once you’ve got it? Aluminum you can’t effectively work is still basically useless.
Aluminum has a lower melting point than copper, so once it’s refined it should be castable with medieval technology.
