- Nick Bostrom's "singleton hypothesis" says that intelligent life on Earth will eventually form a "singleton".
- The "singleton" could be a single government or an artificial intelligence that runs everything.
- Whether the singleton will be positive or negative depends on numerous factors and is not certain.
Does history have a goal? Is it possible that all the human societies that existed are ultimately a prelude to establishing a system where one entity will govern everything the world over? The Oxford University philosopher Nick Bostrom proposes the "singleton hypothesis," maintaining that intelligent life on Earth will at some point organize itself into a so-called "singleton" – one organization that will take the form of either a world government, a super-intelligent machine (an AI) or, regrettably, a dictatorship that would control all affairs.
Other forms of a singleton may exist, and, ultimately, Bostrom believes one of them will come into existence. The philosopher argues that historically there's been a trend for our societies to converge in "higher levels of social organization". We went from bands of hunter gatherers to chiefdoms, city-states, nation states and now multi-national corporations, the United Nations and so forth, all the way to globalization – one of President Donald Trump's favorite targets for attack. One view of that trend sees increased power going to multi-national businesses and world government bodies, making globalization somewhat of a punching bag concept, often seen not as a needed re-organization of societies around the world, leading to increased cooperation and a peaceful international order, but rather for its potential to bring about the loss of jobs and undermine the sovereignties of individual countries, making citizens beholden to faceless totalitarian bureaucrats from foreign lands.
But a singleton doesn't have to result in a bad outcome, argues Bostrom. In fact, he thinks it could also be a good thing or at least something that's neither obviously positive or negative – just neutral. One way to get to a singleton, according to the philosopher, is through technology. Improved surveillance and communication, mind-control tech, molecular nanotechnology and artificial intelligence could all bring about a singleton.
While some aspects of such technologies could certainly be unwanted and infringe upon individual freedoms, Bostrom thinks that there are situations in which there could be broad support for either a technological solution or a single government agency to take control of the society. As the world grows more complex, it's harder to achieve efficient coordination between countries and individuals within them. Tech solutions in conjunction with converging moral values and a democratic worldwide government could facilitate that.
Other scenarios, like catastrophic events, could also hasten the creation of singletons. The League of Nations, for example, came out of World War I, while the creation of the United Nations was a byproduct of World War 2.
Some may view the current political trends of rising nationalism, tariff wars and anti-immigration platforms to mean that globalization and an overall unification of people the world over is not coming any time soon. In fact, it feels like we are going backwards on such a path.
In an email exchange with Big Think, Bostrom cautioned us to not only look at what is happening over the course of a decade or maybe even a few decades. There are much larger, historic trends at work, which may see the current times as a blip rather than a change in the overall direction.
"I don't think there's much evidence in the year-to-year (or even decade-to-decade) political jitters for the question of the long-term fate of Earth-originating civilization," writes Bostrom, while adding "Still, it seems a bit sad whenever the world is moving in the direction of fragmentation and unilateralism."
He would rather see relationships between nations like the United States and China to be cordial rather than the "tussles and tensions" that we get now, with the added risk of a further breakdown in communication leading to even worse outcomes.
"I fear that people have forgotten how bad the Cold War was or have learned the wrong lesson - "well we survived it so it wasn't so bad," warns the philosopher. "But I think it's more like somebody played a round of Russian Roulette and survived and then they say "hey that wasn't so bad, let's play another round!" With the opening of the nuclear archives, we can see how close the world came to the brink on several different occasions. Allowing ourselves to slide into another situation even remotely like that of the Cold War would be a huge mistake."
Political tides certainly can come and go. It might be long until we can definitively tell which era we are living in now. Either advanced technology and a spreading democratic order will create a global techno-utopia of the future or we will be enslaved by corporate hegemony and international oligarchs. There are also options in between. It's important to remember that once created, a singleton could become the way of life for the foreseeable future as it will take measures to stay in existence and to keep away threats.
"Earth-originating intelligent life will (eventually) form a singleton," writes Bostrom.
Before you get set for your life to be dominated by a single agency, Bostrom's classic paper on the subject lays out some specific pros and cons of a singleton.
Four Advantages:
- avoiding dangerous arms races – these are costly and potentially disastrous. Without many competing world powers, arms races would be unnecessary.
- avoiding a space colonization race, again leading to potential war and extreme expenses.
- avoiding inequality - a singleton could distribute wealth.
- avoiding evolutionary outcomes we don't want - a singleton (especially an AI) could better keep track of dystopian scenarios, like epidemics, and work towards the survival of the population as a whole.

Four Disadvantages:
- having one entity control everything could lead to less control over decision-making and things could go bad for us humans. "All the eggs are in one basket" under this scenario, points out Bostrom.
- world without competition between states could be more vulnerable to systemic breakdowns than a world that is less arranged, in which "there are some processes that limit the destructiveness of certain kinds of failures," writes the philosopher.
- some singletons could lead to terrible bureaucracy and inefficiency – it's not certain whether that would outweigh the gains from such a coordinated society. That would depend on the "severity" of the problems.
- some singletons could be created by force - think Ghenghis Khan, Napoleon, Nazis and whatever new dictator is waiting in the wings.

Scientists have reproduced the voice of an ancient Egyptian priest by creating a 3D-printed replica of his mummified vocal tract.
An international and interdisciplinary team, led by David Howard, a professor of electronic engineering at Royal Holloway, used computed tomography (CT) scanning technology to measure the dimensions of the vocal tract of Nesyamun, a mummy that's spent about two centuries on display at Leeds City Museum in the United Kingdom.
The team then used those measurements to 3D-print an artificial vocal tract, through which they produced sounds using a peculiar electronic device called the Vocal Tract Organ. (You can check it out here.)
"The Vocal Tract Organ, a first in its own right, provided the inspiration for doing this," Howard told CNET.
Nesyamun, whose priestly duties included chanting and singing the daily liturgy, can once again "speak" — at least, in the form of a vowel noise that sounds something like a cross between the English pronunciation of the vowels in "bed" and "bad."
Of course, the new "voice" of Nesyamun is an approximation, and given the lack of actual recordings of his voice, and the degeneration of his body over millennia, it's impossible to know just how accurate it is. But the researchers suggested that their "Voice from the Past" project offers a chance for people to "engage with the past in completely new and innovative ways."
Howard et al.
"While this approach has wide implications for heritage management/museum display, its relevance conforms exactly to the ancient Egyptians' fundamental belief that 'to speak the name of the dead is to make them live again'," they wrote in a paper published in Nature Scientific Reports. "Given Nesyamun's stated desire to have his voice heard in the afterlife in order to live forever, the fulfilment of his beliefs through the synthesis of his vocal function allows us to make direct contact with ancient Egypt by listening to a sound from a vocal tract that has not been heard for over 3000 years, preserved through mummification and now restored through this new technique."
Connecting modern people with history
It's not the first time scientists have "re-created" an ancient human's voice. In 2016, for example, Italian researchers used software to reconstruct the voice of Ötzi, an iceman who was discovered in 1991 and is thought to have died more than 5,000 years ago. But the "Voices of the Past" project is different, the researchers note, because Nesyamun's mummified corpse is especially well preserved.
"It was particularly suited, given its age and preservation [of its soft tissues], which is unusual," Howard told Live Science.
As to whether Nesyamun's reconstructed voice will ever be able to speak complete sentences, Howard told The Associated Press, that it's "something that is being worked on, so it will be possible one day."
John Schofield, an archaeologist at the University of York, said that reproducing voices from history can make museum experiences "more multidimensional."
"There is nothing more personal than someone's voice," he told The Associated Press. "So we think that hearing a voice from so long ago will be an unforgettable experience, making heritage places like Karnak, Nesyamun's temple, come alive."

"If you're brave enough to try, you might be able to catch a train from UnLondon to Parisn't, or No York, or Helsunki, or Lost Angeles, or Sans Francisco, or Hong Gone, or Romeless."
China Miéville's fantasy novel Un Lun Dun is set in an eerie mirror version of London. In it, he hints that other cities have similar doubles. On the list that he offhandedly rattles off, Paris stands out. Because the City of Light really does have a twisted sister. Below Paris Overground is Paris Underground, the City of Darkness.
Most people will have heard of the Catacombs of Paris: subterranean charnel houses for the bones of around six million dead Parisians. They are one of the French capital's most famous tourist attractions – and undoubtedly its grisliest.
But they constitute only a small fragment of what the locals themselves call les carrières de Paris ("the mines of Paris"), a collection of tunnels and galleries up to 300 km (185 miles) long, most of which are off-limits to the public, yet eagerly explored by so-called cataphiles.
The Grand Réseau Sud ("Great Southern Network") takes up around 200 km beneath the 5th, 6th, 14th, and 15th arrondissements (administrative districts), all south of the river Seine. Smaller networks run beneath the 12th, 13th, and 16th arrondissements. How did they get there?
Paris stone and plaster of Paris
It all starts with geology. Sediments left behind by ancient seas created large deposits of limestone in the south of the city, mostly south of the Seine; and gypsum in the north, particularly in the hills of Montmartre and Ménilmontant. Highly sought after as building materials, both have been mined since Roman times.
The limestone is also known as Lutetian limestone (Lutetia is the Latin name for ancient Paris) or simply "Paris stone." It has been used for many famous Paris landmarks, including the Louvre and the grand buildings erected during Georges-Eugène Haussmann's large-scale remodelling of the city in the mid-19th century. The stone's warm, yellowish color provides visual unity and a bright elegance to the city.
The fine-powdered gypsum of northern Paris, used for making quick-setting plaster, was so famed for its quality that "plaster of Paris" is still used as a term of distinction. However, as gypsum is very soluble in water, the underground cavities left by its extraction were extremely vulnerable to collapse.

In previous centuries, a road would occasionally open up to swallow a chariot, or even a whole house would disappear down a sinkhole. In 1778, a catastrophic subsidence in Ménilmontant killed seven. That's why the Montmartre gypsum quarries were dynamited rather than just left as they were. The remaining gypsum caves were to be filled up with concrete.
The official body governing Paris down below is the Inspection Générale des Carrières (IGC), founded in the late 1770s by King Louis XVI. The IGC was tasked with mapping and, where needed, propping up the current and ancient (and sometimes forgotten) mining corridors and galleries hiding beneath Paris.
A delightful hiding place
Also around that time, the dead of Paris were getting in the way of the living. At the end of the 18th century, their final destination consisted of about 200 small cemeteries, scattered throughout the city — all bursting at the seams, so to speak. There was no room to bury the newly dead, and the previously departed were fouling up both the water and air around their respective churchyards.
Something radical had to happen. And it did. From 1785 until 1814, the smaller cemeteries were emptied of their bones, which were transported with full funerary pomp to their final resting place in the ancient limestone quarries at Tombe-Issoire. Three large and modern cemeteries were opened to receive the remains of subsequent generations of Parisians: Montparnasse, Père-Lachaise, and Passy.

The six million dead Parisians in the Catacombs, from all corners of the capital and across many centuries, together form the world's largest necropolis — their now anonymized skulls and bones methodically stacked, occasionally into whimsical patterns. The Catacombs are fashioned into a memorial to the brevity of life. The message above the entrance reads: Arrête! C'est ici l'empire de la Mort. ("Halt! This is the empire of Death.")
That has not stopped the Catacombs, accessible via a side door to a classicist building on the Avenue du Colonel Henri Rol-Tanguy, making just about every Top 20 list of things to see in Paris.
An underground economy
However, while the Catacombs certainly are the most famous part of the centuries-old network beneath Paris, and in non-pandemic times draw thousands of tourists each day, they constitute just 1.7 km (1 mile) of the 300-km (185-mile) tunneling total.
Subterranean Paris wasn't just used for mining and storing dead people. In the 17th century, Carthusian monks converted the ancient quarries under their monastery into distilleries for the green or yellow liqueur that still carries their name, chartreuse.
Because the mines generally keep a constant cool temperature of around 15° C (60° F), they were also ideal for brewing beer, as happened on a large scale from the end of the 17th century until well into the 20th century. Several caves were dug especially for establishing breweries, and not just because of the ambient temperature: going underground allowed brewers to remain close to their customers without having to pay a premium for real estate up top.

At the end of the 19th century, the underground breweries of the 14th arrondissement alone produced more than a million hectoliters (22 million gallons) per year. One of the most famous of Paris' underground breweries, Dumesnil, stayed in operation until the late 1960s.
In that decade, the network of corridors and galleries south of the Seine, long since abandoned by miners, became the unofficial playground for the young people of Paris. They explored the fantastical world beneath their feet, in some cases via entry points located in their very schools. Fascinated, these cataphiles ("catacomb lovers") read up on old books, explored the subterranean labyrinth, and drew up schematics that were passed around among fellow initiates as reverently as treasure maps.
As Robert Macfarlane writes in Underland, Paris-beneath-their-feet became "a place where people might slip into different identities, assume new ways of being and relating, become fluid and wild in ways that are constrained on the surface."
Some larger caves turned into notorious party zones: a 7-meter-tall gallery below the Val-de-Grâce hospital is widely known as "Salle Z." Over the last few decades, various other locations in subterranean Paris have hosted jazz and rock concerts and rave parties — like no other city, Paris really has an "underground music scene."

Cataphiles vs. cataphobes
With popularity came increased reports of nuisance and crime — the tunnels provided easy access to telephone cables, which were stolen for the resale value of their copper.
The general public's "discovery" of the underground network led the city of Paris to officially interdict all access by non-authorized persons. That decree dates back to 1955, but the "underground police" have an understanding with seasoned cataphiles. Their main targets are so-called tourists, who by their lack of knowledge expose themselves to risk of injuries or worse, and degrade their surroundings, often leaving loads of litter in their wake.
The understanding does not extend to the IGC. Unlike in the 19th century, when weak cavities were shored up by purpose-built pillars, the policy now is to inject concrete to fill up endangered spaces — thus progressively blocking off parts of the network. That procedure has also been used to separate the Catacombs to prevent "infiltration" of the site by cataphiles.

The cataphiles, however, are fighting back. In a game of cat and mouse with the authorities, they are reopening blocked passages and creating chatières ("cat flaps") through which they can squeeze into chambers no longer accessible via other underground corridors.
Catacomb climate control
Alone against the unstoppable tide of concrete, the amateurs of Underground Paris would be helpless. But the fight against climate change may turn the subterranean labyrinths from a liability into an asset — and the City of Paris into an ally.
The UN's 2015 Climate Plan — concluded in Paris, by the way — requires the world to reduce greenhouse gas emissions by 75 percent by 2050. And Paris itself wants to be Europe's greenest city by 2030. More sustainable climate control of our living spaces would be a great help toward both targets. A lot of energy is spent heating houses in winter and cooling them in summer.
This is where the constant temperature of the Parisian tunnels comes in. It's not just good for brewing beer; it's a source of geothermal energy, says Fieldwork, an architectural firm based in Paris. It can be used to temper temperatures, helping to cool houses in summer and warming them in winter.
One catch for the cataphiles: it also works when the underground cavities are filled up with concrete. So perhaps one day, Paris Underground, fully filled up with concrete, will completely fall off the map, reducing the city's formerly real doppelgänger into an air conditioning unit.

Strange Maps #1083

The prevalence of allergies arising in childhood has increased over the last 50 years, with 30 percent of the human population now having some kind of atopic disease such as eczema, food allergies, or asthma. The cause of this increase is still subject to debate, though it has been associated with a number of factors, including changes to the gut microbiomes of infants.
A new study by Canadian researchers published in Cell Reports Medicine may shed further light on how these allergies develop in children by examining the contents of their first diaper.
The things you do for science
The research team examined the first stool of 100 infants from the CHILD Cohort Study. The first stool of an infant is a thick, green, horrid-looking substance called meconium. It consists of various things that the infant ingests during the second half of gestation. Additionally, it provides not only a snapshot of what the infant was exposed to during that time, but it also reveals what the food sources will be for the initial gut bacteria that colonize the baby's digestive tract.
The content of the meconium was examined and found to contain such varied elements as amino acids, lipids, carbohydrates, and myriad other substances.
A graph of the comparative, summed abundance of different elements in a metabolic pathway after scaling to median abundance of each metabolite. The blue figures are those children without atopy, the yellow ones show the data for those with an atopic condition. Petersen et al.
The authors fed this information into an algorithm that used this data, along with the identities of the bacteria present as well as the baby's overall health, to predict which infants would go on to develop allergies within one year. The algorithm got it right 76 percent of the time.
A way to prevent childhood allergies?
Infants whose meconium had a less diverse metabolic niche the initial microbes to settle in the gut were at the highest risk of developing allergies a year later. Many of these elements were associated with the presence or absence of different bacterial groups in the digestive system of the child, which play an increasingly appreciated role in our overall health and development. The findings were summarized by senior co-author Dr. Brett Finlay:
"Our analysis revealed that newborns who developed allergic sensitization by one year of age had significantly less 'rich' meconium at birth, compared to those who didn't develop allergic sensitization."
The findings could be used to help understand how allergies form and even how to prevent them. Co-author Dr. Stuart Turvey commented on this possibility:
"We know that children with allergies are at the highest risk of also developing asthma. Now we have an opportunity to identify at-risk infants who could benefit from early interventions before they even begin to show signs and symptoms of allergies or asthma later in life."
A model for early childhood allergies
Petersen et al.
As shown above, the authors constructed a model of how they believe metabolites and bacterial diversity help prevent allergies. Increased diversity of metabolic products in the meconium encourage the development of "healthy" families of bacteria, like Peptostreptococcaceae, which in turn promote the development of a healthy and diverse gut microbiome. Ultimately, such diversity decreases the likelihood that a child will develop allergies.
