Post-Scarcity? What is that? Well it is a tricky concept to pin down, even though it means exactly what it says, a civilization or economy in which scarcity of resources no longer exists. Now sometimes people mean no scarcity at all, but generally it is meant to mean low scarcity.

In a finite Universe with entropy, which appears to be what the one we live in is like, you inevitably have scarcity issues so you cannot be completely without scarcity. Once you put that qualifier on things you then have to think of it in more relative terms, which means a big decrease in scarcity. But that has happened before, many times, arguably all the way back when we invented fire and could start living and hunting in colder climates and storing food better. Ditto irrigation and canals dealt with a scarcity of water, a huge bottleneck on agriculture back at the dawn of history. Any number of inventions have decreased scarcity since then. Of course the population typically rose at that point until that commodity either became scarce again or something else did that wasn’t too scarce before.

You get low on land to grow food on and someone invents cheap nitrogen fertilizer made using fossil fuels and the population rises from that and now the demand for those fossils fuels rises for their other applications like cars and electricity. Or you invent a new and better strain of a staple crop that produces 20% more food and the population rises 20%. It is not a zero-sum game, you’ve got more people, but you hit a new scarcity. So we can conclude first that any post-scarcity society either needs to be relatively young so that they haven’t grown to create a new scarcity or is zero growth. Relatively young being the key word there since between improving efficiency of using those resources and an expansion into your solar system and galaxy increasing those resources you might maintain a slow stable growth for millions of years before you hit a scarcity wall again. About the only exception to that is an infinite universe, and even then only one where those no travel bottleneck on par with human lifetimes. For instance, if the speed of light holds you cannot be shipping humans from Earth constantly off to new solar systems since they’d need thousands of years to arrive and eventually you would have systems that were settled long enough ago to have population problems of their own that were much closer to the new territories.

If there were for instance an infinite number of Earths, and we could just open portals up to them with a snap of the fingers you could pretty much just keep sending folks off to new worlds, but there is still scarcity there since only so many could fit on Earth. You might have a billion portals connecting the original Earth to a billion previously uninhabited copies, each of those connected to a billion more themselves as they filled up, all pumping resources in and waste material and heat out but it still fills up eventually. So there is an assumption that any post-scarcity society is either in a temporary growing phase or has stabilized to some level. Fiction tends to show us this at a very tiny number, a few billion people on a planet, but if you saw the Ecumenopolis episode we sort of killed that image. It is a big popular one too, much like the idea of matter replicators from Star Trek, where you just order your tea, Earl Gray, hot, and bang there it is.

3D printing has been making that seem like a potential future reality, but we will poke some holes in the latter later in this episode. 3D printing is awesome technology but it is not a magic wand and probably will not be in the future either. But we are getting ahead of ourselves. We have said post-scarcity cannot be viewed as an eternal absence of any and all scarcity. There will be some scarcity of some things all the time and since the Universe appears to be finite you do eventually have to stop growing.

We have also noted that post-scarcity events have occurred before in human history, with fire and irrigation for instance. So as we try to define this concept for useful discussion we have to have a definition that assumes we are not post-scarcity yet and that it does not require a total absence of any scarcity. There is also often seen to be a psychological aspect to post-scarcity, not in every version but it is a common theme, that people have a bit less of a materialistic view or at least do not go through life focused on Keeping up with the Jones es. Part of that image of post-scarcity comes from people just not going through life focused on having the best and shiniest new toys.

We do want to look at some individual versions of post-scarcity, but they are often in conflict with each other, like most Utopian visions, one man’s heaven is another man’s hell. We also to need to make sure as we dig into this that we are keeping in mind that scarcity of commodities is not just food and widgets. Privacy is a commodity, an expensive one in high tech civilizations too. Being valued by other people can be a commodity, having a good reputation can be as well. These are hard to put exact prices on, but we do sell these now. You can, for instance, hire a Public Relations firm to improve your reputation.

Post-Scarcity Society

Post-Scarcity Society

So we want to avoid an overly-simplistic view of economics and scarcity that assumes we are just talking about material goods. We should probably ask ourselves then what people value. In that context we will just use Mallow’s Hierarchy of Needs in the Theory of Motivation. Now a lot of folks dispute the ranking of needs on his pyramid or the specific labels for them, but he’s the most well-known and generally viewed as solid, so we will use his.

We will get to that in just a moment, to what those human needs are and how they get prioritized, but first let me list off the conditions or criteria we have identified so far for Post-Scarcity Civilizations.

1) Wealthier than now. Everyone is much wealthier or has access to far more resources than right now, as we assume for this video we are not yet post-scarcity, even in our richest countries. We will add to this list as we go along.

This is just our first and most general definition. There is just very little scarcity of the most basic needs like food and shelter. This takes us into Mallow’s Hierarchy because that is the bottom tier. Back in 1943 Abraham Mallow’s published the idea that most motivations and actions by people were based off needs they wanted to satisfy and these could be viewed as a pyramid, where the bottom-most level is purely physiological. Food, water, shelter, a dry place to sleep. We would assume no place classifies as a post-scarcity society if concerns for this need were not either non-existent or so minimal that you barely thought of them. They create no anxiety in anyone who is not emotionally imbalanced. Possibly these are provided by the government automatically, possibly they just make up such a minimal portion of income that it is just a footnote on your monthly budget.

For the purpose of the article we do not care about the specific economic or political system that exists, just that stress and anxiety for 99% of the population is virtually non-existent where the most basic physiological needs are concerned. If someone is stressing out about it, something very abnormal has happened. Like they got trapped on vacation somewhere and went hungry for a while and are a bit traumatized by that. This is handy one too because we have many examples of sub-groups of society for whom this is already true, even in historical times when most people had to worry a lot about where their food was coming from. Many an ancient king had to worry about food, but that was for his citizens or army not himself and his close friends and family.

We can look at the lifestyles and diaries of historical figures who were raised without that concern and surrounded by others without it to get some idea what that is like, we can look at much of modern culture in developed nations too. This will get harder as we go up the hierarchy. The next level is almost easier to think of as the long-term concern about physiological needs. Where my food is coming from in a decade instead of tonight, concerns that remove much of the immediacy which can cause desperation to interfere with clear thinking. The second tier up, there are five, so the fourth tier, is Safety. Physiological needs are our bottom fifth tier, needs for safety is the fourth. Safety from crime, financial safety, usually the kinds of safety with less immediacy. When you aren’t starving or freezing to death or actually being attacked you have time to worry about if your pension fund is stable. If your job is secure. If you live in a bad neighborhood. So we will add on another condition, our second condition.

2) Safer than Now. Post-Scarcity societies should have far lower concerns about violence directed against individuals as there is less desperation to drive crime and fewer concerns about long term safety and security. And I should add that when I talk about concerns or anxiety I mean rational ones. Doping your civilization up with bottled bliss and propaganda about how great everything is when it is in reality a total dystopian cesspit would not count. Alternatively, I would argue that a society where things were quite wealthy and safe but everyone freaked out about the smallest whiff of trouble would not count as post-scarcity.

As we go through these there is an assumption that both the perception and reality are decently close to each other. When they are not it might make for some good fiction, folks thinking they live in paradise when it is actually a horrible slum, or folks living in paradise who are nervous wrecks or spoiled brats, but I would not classify either as post-scarcity because I generally consider access to reasonably honest information and the ability to gain wisdom as commodities that should not be scarce either. So we’ll toss that in as number 3.

3) Access to abundant, honest information Post-scarcity civilizations have strong access to honest information and some form of education and life experience that tends to assure most folks are not going to assume photos of Bigfoot must be real because they saw them on Facebook. Okay, tier 3 of Mallow’s Hierarchy is the need for love and a sense of belonging. This is when a lot of post-scarcity models starts to get less complete and diverge.

For instance, a more Marxist flavored post-scarcity civilization assumes everyone getting their needs for food and safety, short and long term, provided by the government while a more libertarian one is assuming everybody still pays for them it’s just they are so minimal as concerns though only very strange events could cause it to be otherwise and you’d have a government safety net or private charities or friends and family to help. They both, along with all points in between, assume it is minor matter. When we start getting into love and a sense of belonging it is not just about how these things should be provided but if they even need to be for a civilization to qualify.

I would argue that one way or another these still need to be far easier to achieve than now to qualify a civilization as post-scarcity. How is somewhat irrelevant, also potentially creepy. Most of us would not be too sanguine about moving into a new town and getting a letter from the Department of Emotional Fulfillment giving us advice on dating. Dear Isaac, here is a list of single young ladies in your area and their phone numbers ranked by optimization to your mutual tastes, top of the list is Jessica Smith and her second favorite cuisine is Italian, your own number three, so we have made reservations for you at the local Bistro for next Tuesday. Please make sure to fill out both form 307, predating consent form, and form 308-E, your post-date satisfaction survey. I mean that would be just plain weird, coming from the government anyway, we not only traditionally put up with that sort of meddling from our friends and family but many modern dating websites apparently take it a good deal further and charge with access and have no shortage of customers.

This is also where the internet starts coming in, because it also includes belonging and these days that means you do not just need to seek a sense of friendship from a small pool of a few hundred folks in your home village, but that you have got an entire planet to connect with folks who share your hobbies and passions. Which is mostly a good thing, I think, we have examples like this channel, though of course it can breed echo chambers too. So how this gets done is impossible to say, just that a post scarcity society ought to be better at it then now, but I would imagine in the short term we will just see it get easier and easier for people to connect to those they can have rewarding relationships with even when their eccentricities and behaviors deviate greatly from the norm.

This was one of the great advantages of the rise of cities for instance, it was possible to find and meet up with folks with very atypical interests. A village cannot have a post-stamp collecting club, a large city can. Now you can find folks around the world who share your passion for stamp collecting, and it is getting easier to encounter those with shared interests. So you can find that special guy or gal who you have a ridiculous amount in common with, or those friends who genuinely share your more obscure interests. So we will add that in as condition 4:

4) Large Diverse social pool Maslow’s next tier, number 2, is esteem, both the feeling of prestige and respect from others and for yourself. That gets quite tricky because we can see low self-esteem or feelings of being underrated as a regular thing even among those modern and historical cultural groups with resource abundance like the aristocracy. Frequently folks even achieve this feeling by being dominant over others and that is kind of tricky to achieve across the board. How much society is responsible to help people out with this is also hard to say. Many would say not at all, but most of us would say that it is our responsibility to help our friends and family feel good about themselves and that either the government or private groups need to maintain something like suicide hotlines. Suicide could easily be the number one cause of death in high-tech civilizations.

So however it accomplished it would seem a post-scarcity society needs to be better at helping folks feel their life serves some sort of purpose. This is apparently at odds with quite a few visions of Utopia where frequently folks are not seen as needing a purpose, but in those, even the ones that outright embrace hedonism as not only acceptable but the paramount goal, it might still be satisfied by simply focusing on the notion that having as much fun as you can is the goal. So either you are changing people’s mindsets to feel fulfilled easier or you are making it easier for them to acquire that sensation.

Now just as I said tier 4, safety and security, was a sort of the long-range version of the bottom tier of physiological needs I would say this tier is a bit of an extension of tier 3, needs for love and belonging. I think many of us obtain a large part of our self-esteem from the ability to meet the needs of the lower tier and help others do that too. The funny thing is that more prosperous a society gets the harder it is in some respects to achieve those types of fulfillment that come from either being very useful to others or being the best at something. This blends into the top of the pyramid, tier 1, self-actualization.

This is a quite vague category and one that gets argued about a lot, Mallow even sought to replace it later on with self-transcendence and typically lists of traits of people who are self-actualized get even vaguer and seems to shift definition from author to author. Self-acceptance, a value for truth and honesty and justice, feelings of autonomy, a sense of humor that is not cruel, and many others tend to be regular features of it though. We all know what it is, the sorts of things you pursue when your other needs, from the most basic need for food to the more complex needs for belonging and self-respect. I doubt any two people would make the list the same, but I will combine it with the second tier to make another post-scarcity condition.

5) Sense of Purpose This need not be a single purpose, merely that members of this civilization by and large have a feeling of purpose. They do wake up with an agenda of things they want to get done even though they generally do not have a fear or anxiety component driving them on. They are not getting out of bed in the morning for fear that if they do not they will starve to death and lose all their friends and family. Now individual folks might add more to the list but I think we have five conditions here that most would agree should be features of a post-scarcity civilization.

They are wealthier than now and safer than now, so that there is very little concern for meeting their basic survival needs at the moment or in the future. They have heavy access to information and can generally trust that it is honest or that they can mostly see through dishonest or confused information. They have access to a large and diverse social pool from which to seek relationships with others, and most folks have a sense of purpose about life. Now I did not add it in as a condition, but far superior automation is probably in there. You do not necessarily need much more advanced machinery than we have now to do this but it sure helps. The specific case where you have access to machine intelligence which is outright superior to existing human intelligence we will cover next week in the Technological Singularity article, and we have previously discussed trans humans and super-intelligence. These could easily be part of a post-scarcity civilization; in fact, many believe it is the only way you could even have one. I think they probably will be and make the job easier but I do not view them as an absolute necessity. That is a recurring theme when I talk about advanced civilizations on this channel, either in this context or the Fermi Paradox.

I do not try to figure out how such societies will operate or how they best operate and assume that such societies must exist having those traits. I try to figure out how they could not operate, and assume that anything inside those specific bounds is possible. It is entirely possible civilizations inevitably converge to some form of political or social or economic model but unless I can see a clear incompatibility I assume it is possible and probably happened somewhere in the Universe or Multiverse. I do want to take a moment to talk about both automations in terms of 3D printing and money though. Two of the biggest tropes of post-scarcity civilizations is that there is no money or that you can just have a cup of tea, or anything you want, assembled on the spot. Now the tea is kind of silly, any post-scarcity civilization is not going to have a problem providing rapid access to tea. But since the rise of 3D printing we have developed a bad trend of people thinking it could act like the replicators from Star Trek. You cannot print a cup of tea, that is just wrong at so many levels. You also can not print large and intricate things quickly with 3D printers and it is not something we can just get faster and faster at. We can get a lot faster at it but there are limits.

We will use a simple example. Consider a classic one-nozzle printer, presumably able to spit out a molecule or even an atom of its choosing to the exact right place. I want to build a 3D computer chip about the size of a tea cup, call it a cube ten centimeters or four inches a side. Such an object has something in excess of 10^25 atoms in it. So if you wanted something in under 10 seconds it would need to spit out a trillion-trillion atoms a second or more. Now that is no big deal in and of itself, your kitchen faucet does that when you turn it on. But it has to place them exactly, one at a time, in a line of about a billion atoms long, wide and high. Meaning it is basically drawing a line 10 centimeters long a billion-billion times in ten seconds. That is around a light year long, needless to say your 3D printer nozzle cannot be moving totals of light years in a second, especially since it would need to accelerate and decelerate to those speeds, far in excess of the speed of light, trillions of times during that.

Now you might say, “hey, we can use multiple nozzles right?” and of course we can, you can not realistically get an equal number of printing nozzles as lines you would need to draw on each layer but you might be able to get it down enough so you maybe only needed to make a few passes for each layer. So maybe your printer only needs to make a billion passes to assemble this object. It only needs to cover 100 million meters, basically the distance to the sun, to get the job done.

So only many times the speed of light, which it is jumping up to and down from hundreds of millions of times a second. Nothing can go that fast, the acceleration of doing it would reduce the machinery to atomic dust, and everyone nearby would be killed from energy released from air friction. And by nearby I mean on the same planet. Intricate 3D printing done at high speed is totally the realm of fiction. It is complete nonsense. You cannot just print people for instance because you have to do that so fast the water and other liquids and gases do not just gush out while you are doing it. It is not very often I call an individual piece of popular science fiction technology complete BS but this is one of them.

3D printing is amazing tech, it will give us the option to make intricate things we could not otherwise make and to do some stuff quite quickly where the thing being printed is homogeneous so that we can use a wide nozzle. Like printing buildings with concrete or plastic, or assembling a particular tool at home rather than needing to go to the store and just throwing it into the recycler when we are done with that task.

But it has limits, it is not a magic wand, and printing speed is fundamentally limited by mundane things like the speed of sound, let alone light, and how much acceleration the machinery can handle. You probably could print food for instance, using some basic stocks of materials being printed at a higher resolution than our eyes and mouth could notice, and on timelines faster than popping a premade meal in from the microwave perhaps. That is certainly convenient, you send your kitchen computer a note telling it you want the following meal and it brings it by a few minutes later, because you can heat food a lot faster if you are assembling it at the small scale as you go. Or maybe your building or neighborhood has one and a drone pops in to deliver your meal.

Post-scarcity does not necessarily mean everybody has everything in their own home after all. It is about convenience and efficiency, so there might be a local fleet of automated cars hanging around when folks needed one that drive over and pick you up, unless you really wanted your own. This brings up money because there will always be weird things people want for whatever reason and unless you are tampering with human psychology you have to be able to meet those needs or you are not post-scarcity. Which is fine, a lot of Utopias do assume people are being educated to rise above certain needs, but again we are trying for the widest possible picture. You probably could have a society that did not have money but basically every hypothetical or fictional go at this I’ve seen either just does this by proclamation or just gets rid of money by calling it something else.

That slams up against my own suspension of disbelief. Even in a system where everyone is allowed a monthly ration of stuff automatically just for being alive, and a ration so high it exceeds almost any plausible needs at a monthly level, that is still money. We have also had societies in the past that lacked money, they just had barter of goods, even at the most basic tribal and family level the exchange of favors and goodwill acts as a type of currency. At the most basic levels currency is a means of exchanging favors, reduced to a generic form that can be used for almost anything by almost anyone, including people you do not know. Whenever I have read or watched fiction in settings where they pride themselves on having no money, I repeatedly see them use it they just do not call it that.

Now with extreme abundance a lot of things could end up essentially free, when was the last time you bought air after all? And I do not mean canned air for cleaning electronics or air tanks to go SCUBA diving. I would say it is probably possible to create a society that just had no currency except for major projects but it would still need a way of dealing with ridiculous requests. Like John suddenly wants one million cheesecakes delivered to his house. What do you do? Does this never happen because people have been educated or programmed not to do such things? Do you tell John to login to a virtual reality where that is easy to do? Does John need to go into see a citizen council that will decide whether he gets them, does not get them, or gets sent in to see a psychologist? Do they grant them as a special favor to John, because he has a halfway decent reason in their eyes but also deserves in their eyes some extra leeway for past accomplishments?

So I do not see a compelling reason why a post-scarcity civilization would need to be money-free to work, and indeed it would look like they either need it or need some sort of control system to handle either abnormal requests or prevent them happening. The former is still arguably money and the latter does smell a touch Orwellian to me, but I may just be biased on the matter. There is coercion and there is coercion after all. Most of us think folks should be allowed to believe whatever they want. We usually draw the line somewhere though especially when it comes to acting on it. I am not going to haul John off to an indoctrination center because he insists 2+2=5 but I certainly am not going to accord him any respect for that belief or let him short change his customers when they hand him a $5 bill for a $2 item, and he gives them back two bucks in change. Even potential societies based on Voluntarism, the notion that all interactions must be voluntary by both parties, assumes at least a minimal level of coercion because you still need folks to help ensure agreements are carried out and that something is done about the guy who has gone crazy and started chasing people with an axe.

The flip-side the post-scarcity benevolent dictator, might actually hold the threat of chopping people’s heads off if they disobey. So there is a very wide spectrum of options there but it would look like coercion, while not necessarily absent in post-scarcity societies, ought to be on the low side, relatively speaking. It is very hard to coerce people into doing something or at least the coercion is minimal, either being minor or incredibly uncommon. Now I mentioned virtual reality a bit ago and that is an example of a technology that like advanced computers and automation or energy abundance from something like fusion would tend to be a highly likely component of most post-scarcity societies. That does not require elaboration, you might dip into personal or shared realities to suit your tastes or live in one all the time.

But I thought I would mention a less common example in fiction I think gets overlooked a lot and would seem more likely to be a regular feature in a lot post-scarcity societies. Alistair Reynolds used it in his Revelation Space Series, one of my favorites, so I will keep his name for it. Entoptics.

Entoptic Phenomena is an actual thing, it refers to visual effects that occur in the eye, for instance floaters, those little squiggly chains you see sometimes, or blue field entoptic phenomena, blue sky sprites that sometimes zip across your vision when looking at a bright blue sky, which are just white blood cells moving through capillaries near your retina. Reynolds use it to cover virtual reality overlaid on the here and now, with an assumption that the image was being generated in the various implants almost everyone in that setting had. This would not just be your own imagery either, like me having my brain implants set to display in my vision the name of a person I encounter when I see them, floating over their head. This would have them sending a signal so that if I had my entoptics on I saw them as a redhead instead of blonde and with a bunch of pixies swirling around them.

And presumably there would be setting levels so you could view that as very vivid or know it was clearly projected or shut them off entirely or have it so anything dangerous or ridiculously was screened out. This was limited to visual phenomena but it could be boosted up to include other senses and be quite smart about it, so that if I want to talk to my friend on the phone he appears as though he is sitting in my living room while I appear to be pacing around his garage and all sorts of software is running to keep it mostly seamless, so he is not aware I’m pacing around in my pajamas with my hair all ruffled and the sound comes through just like I was there in person.

It is a virtual reality overlaid with actual reality and customizable to tastes. Taken fairly far I could have my instant tea produced by replicator because all my senses are showing me that is what I am drinking and even holding when in reality a little drone slammed out of the wall with some electrolyte rich room temperature cup of water in a container that can alter its shape a bit to fit my hand like the teacup would. It is still in many ways a virtual reality but again one overlaid with reality and makes for a nice blend of both. John can have his million cheesecakes delivered because anyone who walks by and has their entoptics on is going to see, and possible smell and feel, a million cheesecakes sitting on John’s lawn. Again it is not anything you could not do in a virtual reality but it straddles that comfort zone a lot of folks have with the idea of being plugged into something fake.

That is one of the best options though, video games and interactive television leading to entirely simulated full immersion setups where you are not just limited to voluntary interaction with folks but can run around chopping the heads off zombies or ruling as a dictator or doing any number of the sorts of things the internet is best known for providing but will not get explicitly mentioned on this channel which I try to keep family friendly, but what we know almost everyone in Star Trek probably actually uses the helideck for. We have had to skip a lot, I did not go into much about what day to day life might be like, something I regret skipping in last week’s asteroid mining article, in terms of talking about what life living at an asteroid mine or traveling back and forth between one would be like. Here, while I wish I could have gone into it, the problem is we have not got much to work with. Fiction offers a lot of options, but so many post-scarcity societies are so different we cannot say much besides that post-scarcity civilizations ought to be low on anxiety and personal fear.

Post-Scarcity World

Post-Scarcity World

I do have a couple blog announcements, and a poll, so stick around for those, but let us wrap up on post-scarcity. And with the reminder we have skipped those versions of it relying on super-intelligent computers which is something we will look at, among other topics, in next week’s Technological Singularity article. We have seen that post-scarcity civilizations can probably come in a lot of forms. I have no idea which is any of these will be the one we get two or when that will happen, but I tend to think we would see several types emerge and probably in our own lifetimes. I would have liked to discuss privacy concerns in high-tech civilizations too but that would be a whole extra content.

I do not think many would be likely to be dystopian, and they are often portrayed that way too, going all the way back to HG Wells 1895 novel Time Machine where the Eloi are happy slave cattle of the Morlocks. There are certainly real concerns related to that though, I just mentioned privacy, and of course we always have the concern that without challenge and hardship a civilization might degenerate, like the Eloi did, into a bunch of mindless spineless cretins. There are definitely some challenges to avoiding that, in a society where for instance every child might be born with a genetically flawless mind and body and with all sorts of neural implants and machines running around at their beck and call, essentially king of their own personal domain, something that got looked at way back in Isaac Asimov’s novel the Naked Sun, and I think what Jakub was aiming for with this episode’s cover art.

Dealing with those I think is still mostly in the realm of fiction though and the fields which cover such matters are not my own, so I will leave those undiscussed besides noting that we discussed way back in the Simulation Hypothesis episode that you might dump kids or maybe young adults with their memories temporarily wiped into simulated realities where there was hardship present, in controlled fashion, so they themselves did not get too directly traumatized, so that they could experience that and incorporate it into their thinking without having to actually be at risk.

So I do think it is a manageable problem and not a Fermi Paradox solution for instance, where all high-tech civilizations fall to pieces from them all being spoiled brats.

Our topics for the week after next are Dark Energy, the mysterious substance that seems to be making our universe expand, a discussion of SETI, the Search for Extra-terrestrial Intelligence, Cryptocurrency and associated topics like bitcoin and Blockchain, and von Neumann Machines, the idea of tiny little robots that swarm out from earth colonizing the galaxy for us or committing acts of genocide, often called Berserkers.

You guys pick, and that will be the next episode after Technological Singularities, and we will follow that in EduQuarks.
