Need redundant systems? (Backup WHO and CDC?)

 Humans tend to have two of many of their internal organs — two livers, two kidneys, two lungs, etc.

Humans even have two hemispheres in their brains.

This is based on the basic principle of bilateral symmetry that emerged a half-billion years ago that underlies the developmental blueprints of so many animals.

Not all animal species manifest bilateral symmetry.

Crabs, with their one big claw and the other tiny claw, are examples of bilateral asymmetry.

Starfish are examples of radial symmetry.

Indeed, even a bilaterally symmetric species like humans have only one stomach and one heart.

But bilateral symmetry is very common because it has its advantages.

One advantage is redundancy.

If one organ fails, there is a backup.

Redundancy is expensive and inconvenient.

Think about how lugging around a spare tire in a car can be a hassle.

Or, think about a military that seems to spend most of its time doing nothing.

The spare tire and a nation’s military can seem like an inefficient use of resources.

But there is a difference between efficiency — and the pursuit of greater efficiency is an imperative in normal periods of history — and survival in a future time of a crisis.

Redundancy is an insurance policy.

The fact that redundant systems are so common in the natural world points to the need for such inconvenient investments.

Aside from the redundancy of bilateral symmetry, there is a second issue with regard to dualities found in natural systems.

For example, the human brain often consist of dual systems.

However, these are complementary systems that work together, and are not examples of bilateral symmetry.

For example, regions of the brain devoted to math are distinct from areas dedicated to language.

These two systems do not work in tandem.

“Where mathematical ability comes from is a long-standing question. Our research helps to show that advanced mathematical reasoning relies on dorsal parietal and frontal areas of the brain and totally spares brain regions involved in language skills,” Says Marie Amalric, a PhD student who co-authored the paper with Dehaene.

The same regions were used for all four domains of mathematics tested: analysis, topology, algebra and geometry.

The results suggest that ability in higher mathematics relies on the same basic circuits that everyone uses for our intuitions about space, time and number awareness. Although language processing may be used while learning mathematics, mathematical reasoning itself seems to happen in its own parts of the brain.

Within the regions of the brain dedicated to mathematical processing, there is a distinction between areas that focus on number tasks and areas devoted to calculation tasks.

Of course, these two types of areas work together in our processing of math problems.

4. Conclusion

These meta-analyses investigate brain activity in children that underlies processing of number and calculation tasks. These are the first meta-analyses in children younger than 14 years distinguishing between number and calculation tasks. Based on these results we sketched a neuropsychological developmental model of mathematical cognition in stereotaxic-space. We find that mathematical performance in children emerges from known core-regions associated with number processing, such as parietal and frontal areas; but it also emerges from regions not previously recognized in a mental-arithmetic network, such as the insula, the claustrum, and the cingulate gyrus. The insula, in particular, may play a critical role in children’s mathematical calculation, because children need strong intrinsic motivation and affective goals to cause their effort in attention and complex processing. Future behavioural and neuroimaging work on children’s mathematical cognition should benefit from a refined topographical atlas of mathematical processes in healthy children.

Perhaps the logic of bilateral asymmetry and complimentary systems can be applied to national and international institutions.

Take, for example, the World Health Organization and the Centers for Disease Control and Prevention.

They are sometimes described as having failed in much of their mission during the SARS-CoV-2 pandemic.

Much of the criticism of the WHO in particular takes the form of scapegoating by national leaders eager to distract the public from their own shortcomings during the crisis.

However, it does seem that the WHO tends to adopt the official perspective of powerful countries, even in matters unrelated to public health (e.g., the status of Taiwan).

To be fair, diplomacy is central to the WHO’s mission.

The WHO cannot function without the cooperation of governments.

Likewise, the CDC is somewhat discredited, especially because of its disingenuous policy on masks.

Only N95 respirators, which are in short supply, would adequately protect frontline healthcare workers.

In order to protect the supply of N95s, the CDC declared that masks in general were unnecessary.

Like university presidents, the WHO and the CDC are run by scientists and scholars who by necessity have pronounced political orientations and strong diplomatic skills.

However, it might be useful to create institutions parallel to the WHO and the CDC.

These new institutions would be strictly scientific and remain autonomous from government influence.

Perhaps universities at the national and international levels could create an independent network somewhat modeled on the internet.

There would be a ground-up, parallel and independent institution providing information and advice to the public distinct from the WHO and the CDC.

This way, for example, it would be more difficult for the national government to hijack critical information on a pandemic statistics.

Need new coins or no coins at all? (Lindy effect)

 There is a shortage of coins in the USA because of the SARS-CoV-2 pandemic.

Some argue that the penny in particular should simply be eliminated.

https://www.nytimes.com/2020/07/29/business/coin-shortage-penny.html

Each penny costs about 2 cents to produce, according to a 2019 report by the United States Mint. Pennies accounted for 59 percent of the 12 billion coins the mint manufactured last year.

Some people support the penny for sentimental reasons. It was one of the first coins made by the Mint after it was established in 1792.

Another reason, offered by Americans for Common Cents, an advocacy group that provides research for Congress on the value of the penny, is particularly pertinent during a pandemic: Older pennies are made mostly of copper, which is antimicrobial.

One path away from the penny might be found in civil society.

Civil society is the public/private realm distinct from the government, on one end, and the private individual, on the other end.

Civil society refers to businesses, clubs, associations, and so forth.

https://en.wikipedia.org/wiki/Civil_society

Civil society can be understood as the “third sector” of society, distinct from government and business, and including the family and the private sphere.[1] By other authors, civil society is used in the sense of 1) the aggregate of non-governmental organizations and institutions that manifest interests and will of citizens or 2) individuals and organizations in a society which are independent of the government.

If a major cash businesses like Walmart or fast food outlets simply stopped pricing for pennies, the penny shortage would be significantly alleviated.

The article alludes to how avoiding pennies — and nickels and dimes — would make life so much easier for businesses.

The article also explains how not using pennies would not hurt consumers because business round down as much as they round up.

The article also mentions that there was once a half cent in the USA that was eliminated in 1857 because everybody hated it.

https://en.wikipedia.org/wiki/Half_cent_(United_States_coin)

Adjusted for inflation, the half cent in 1857 would have been worth about 14 cents in 2019.

That means that by the standards of 1857, not only is the penny unnecessary, but so are the nickel and the dime.

It also means that back in 1957, the penny roughly had the today’s value of about 28 cents.

So today, the quarter would be the proper replacement of the penny.

Why do we even have coins like the penny, the nickel and the dime?

According to the internet, the nickel and dime cannot be eliminated unless the penny is first eliminated.

And Americans love, love, love the penny.

People love the penny because it has a warm, copper color and because it has Abraham Lincoln’s image on it.

If a new 50-cent or one-dollar piece that was bronze were printed and if it had Abraham Lincoln’s likeness on it, then the penny, nickel and dime would be eliminated.

This brings up a different issue.

Should all forms of cash be eliminated?

The new reality in a SARS2 world is digital payments.

People who only used cash are now using their smartphones to make digital payments.

https://www.nytimes.com/2020/07/06/business/cashless-transactions.html

Cash is certainly not dead. Before the pandemic, bills and coins were used for 80 percent of the transactions in Europe, and there are few signs that the pandemic is about to wipe it out.

Propelling the trend is a surge in online shopping as homebound consumers turn to digital tools for basic items. In the United States, 40 million customers went online for groceries in April. In Italy, where cash is king, the volume of e-commerce transactions has surged more than 80 percent, according to McKinsey & Company.

Visa reported a surge in contactless payments for basic items in Britain after limits there were lifted and a 100 percent increase from a year ago in the United States.

There are problems with a cashless economy.

The authorities that manage the world’s currencies say the dangers of going fully cashless are rife. In tech-forward Sweden, cash has been disappearing so fast that Parliament and the central bank asked commercial banks to keep bills and coins circulating while they figure out what a cash-free future would mean.

Consumer groups warn that vulnerable people risk being marginalized. Many low-income earners and retirees, as well as some immigrants and people with disabilities, have little or no access to electronic payments and are increasingly shut out as banks cut back on A.T.M.s and customer service.

Governments are looking at the possibility of switching to digital currency.

Central banks are looking at whether electronic currencies can replace physical cash. The Swedish Riksbank is testing a pilot version of a digital krona, or e-krona, that could keep the functions of a currency backed by the state.

“In certain economies, there is still a role for cash, because it continues to provide a benefit and a utility,” said John Velissarios of Accenture, which is helping to manage the Riksbank’s test. “That’s where the concept of things like digital central bank money is interesting,” he said.

The adoption of government-backed digital currency might not mean the demise of cash.

But it would probably spell the end of bitcoin.

On the one hand, bitcoin would no longer be the first thing that most people think of when they think of virtual currency.

On the other hand, bitcoin might appeal only to limited, niche markets.

These customers might discover that bitcoin is less useful than they imagine.

Survivalist used to prepare for the end of the world by buying gold.

Nowadays, many of them are buying bitcoin.

But when the grid goes down, how exactly does one use bitcoin?

For that matter, how would one deal with all that gold while hiding in the forest and foraging for food?

In wartime, people in anarchic regions trade with cigarettes or alcohol, or they barter.

The topic of barter begs for a very brief history of exchange.

In a hint of things to come, it must be recognized that cash consists of coins and notes.

Coins have been around for a long time.

Banknotes are more recent.

https://en.wikipedia.org/wiki/Banknote

The first known banknote was first developed in China during the Tang and Song dynasties, starting in the 7th century. Its roots were in merchant receipts of deposit during the Tang dynasty (618–907), as merchants and wholesalers desired to avoid the heavy bulk of copper coinage in large commercial transactions.[8][9][10] During the Yuan dynasty (1271–1368), banknotes were adopted by the Mongol Empire. In Europe, the concept of banknotes was first introduced during the 13th century by travelers such as Marco Polo,[11][12] with European banknotes appearing in 1661 in Sweden.

Coins are “Lindy” compared to banknotes.

This is an allusion to the “Lindy effect”.

The projected future life expectancy of some non-material thing is about as long as the current age of that thing.

Things that have been around a long, long time will probably still exist a long, long time from now.

More recent things will probably not be around for so long.

https://en.wikipedia.org/wiki/Lindy_effect

The Lindy effect is a theory that the future life expectancy of some non-perishable things like a technology or an idea is proportional to their current age, so that every additional period of survival implies a longer remaining life expectancy.[1] Where the Lindy effect applies, mortality rate decreases with time.

Again, this refers to non-substantial things like concepts.

“I [Taleb] suggested the boundary perishable/nonperishable and he [Mandelbrot] agreed that the nonperishable would be power-law distributed while the perishable (the initial Lindy story) worked as a mere metaphor.”

For example, a particular old gold coin might get lost or discarded or melted down.

But the idea of coins and the technology of coin-making will persist.

What is even more Lindy than coins is barter.

In fact, one’s social and familial life might be seen to consist of various forms of barter that are carried out unconsciously.

That is, our personal lives involve all sorts of tacit quid pro quo.

In contrast, the world of modern work is compensated by money.

So, we still have a barter economy that is central to our lives, we just don’t think about it.

Cities would be another example of the confusion between the lifespan of material things and the life expectancy of the IDEA of that thing.

One might say that Damascus is more Lindy than Seattle because Damascus is one of the oldest cities in the world whereas Seattle dates back to the 1850s.

That assertion would be an error.

This is because it is the idea of cities that is more Lindy than, say, suburbs, which are parasitic off of cities, and thus more recent.

Even less Lindy than the suburb would be an “exurb”.

Exurbs have been described as the suburbs of suburbs.

That is, exurbs are “areas beyond suburbs and specifically less densely built than the suburbs to which the exurbs’ residents commute.”

https://en.wikipedia.org/wiki/Exurb

An exurb is an area outside the typically denser inner suburban area of a metropolitan area, which has an economic and commuting connection to the metro area, low housing density, and growth. It shapes an interface between urban and rural landscapes holding an urban nature for its functional, economic and social interaction with the urban center, due to its dominant residential character.

To some extent, much “small-town America” is no longer composed of semi-self-sufficient communities based on agriculture.

Many of the “rural” areas in the USA are commuter exurbs, where people drive to another suburb for work.

According to the Lindy effect, these so-called “rural” places in the USA would be very fragile economically.

In sum, cities would be more resilient than suburbs and exurbs, but perhaps less Lindy than agricultural communities.

But what exactly is a city?

In the USA, a city is where people in a metro area commute to work, at the heart of which is the downtown central business district.

However, historically, “cities” were originally just towns.

There is no clear line between a city, a town and a village.

Arguably, if one were to journey back to ancient Athens — supposedly the greatest civilization in history — it would be striking in its village mode of existence.

In this case, it is better to talk about not cities, but settled life, which is less Lindy than nomadism.

In fact, settlements might have preceded agriculture.

The original settlements might have originally been temple complexes that date back 12,000 years.

Perhaps it was religious ritual that led to settlement, and this paved the way for the development of agriculture two thousand years later.

https://en.wikipedia.org/wiki/G%C3%B6bekli_Tepe

So, the most Lindy way of life would have been

  • nomadic and based on
  • barter.

That is, settled life and money are less Lindy than nomadism and barter.

Again, the issue is not particular physical cities or forms of money, but the idea of settled life and of cash.

The Lindy-ness of civilizations is a more tricky topic.

While a particular coin or type of coin is perishable, and the idea of coins is imperishable, particular civilizations are to some degree both perishable and imperishable.

This is because particular civilizations are cultural complexes — and thus non-perishable — just as much as they are material realities.

This applies to the city-states of ancient Greece.

Of course, Greek city-states together comprised a civilization.

But each city-state by itself was a distinct civilization just as much as they were physical cities.

After all, the backup plan for the citizens of ancient Athens in the face of a Persian invasion was to load everyone in ships and move to Sicily and reestablish Athens.

It would have been the same city in their minds because it would be the same people with the same way of life, albeit in a different location.

It can thus be tricky to say that a particular bricks-and-mortar city is Lindy because it is hundreds or thousands of years old.

For example, we can say that because the city of Rome is three thousand years old that it will probably persists for another three thousand years.

That might be confusing the material city of Rome for the Roman ideal.

For example, the science fiction writer Philip K. Dick had a dream in which a voice told him that “The empire never ended.”

That is, culturally, we still live in the Roman Empire, which presumably will last for another 2,500 years.

The material Roman Empire was overrun by Germans tribesmen.

But the kingdoms that these tribesmen established later became empires and republics along the lines of Rome.

The Lindyness of Italian culture was explained by an old Italian man in Joseph Heller’s “Catch-22”.

He explained to an American soldier that Italian civilization is three thousand years old, and that — unlike America — it will still exist three thousand years from now.

This is actually complicated.

If one is talking about nation-states, modern Italy has only been in existence only since 1870.

https://en.wikipedia.org/wiki/History_of_the_Kingdom_of_Italy_(1861%E2%80%931946)

The Italian nation-state has only been around for 150 years, so it might be expected to come to an end within 150 years.

The American civic-state has been around for 250 years, so it might be expected to last for another 250 years.

So, the actual Italian state might only last another 150, but Italian culture will probably just keep chugging along for another 3,000 years.

But “American civilization” does not have such an assured future.

A distinct American identity did not exist until about 1800, and even then it was awkwardly maintained.

The conscious attempt to forge a distinct American culture might be dated to around 1830, when Noah Webster published his modernized dictionary.

So, the American state might last another 250 years, but an American identity might only last another 220 years, and American culture might only last another 190 years.

https://en.wikipedia.org/wiki/Webster%27s_Dictionary

Unfortunately, even talking about an “American culture” might be problematic.

To even speak of an “American civilization” seems weird — even like an oxymoron.

There is that old joke that the USA is the only country to go from barbarism to decadence without an intervening period of civilization.

Again, decadence is not decline, but rather a period of complacent, self-indulgent, sterile prosperity that precedes decline.

In that light, the USA now seems like it is transitioning from decadence to a classic period of decline.

Decline is characterized by the absence of the “creative response to challenge” that originally built the society (Toynbee).

But unlike decadence, real decline in all its scariness can trigger fundamental reinvention and re-invigoration.

So perhaps the USA will last another 250 years.

And coins and cash will probably still be around then — at least, according to the Lindy effect.

Again, barter is more Lindy than coins, which are more Lindy than banknotes, which are more Lindy than cryptocurrency and digital payments.

So, barter might be an overlooked resource that we will all need to fall back on.

Thus, it might be a good idea to stock up on three months worth of food the way Mormons do, as well as build up a barter network.

In fact, one might want to have a diversified portfolio of forms of payment, including:

  • items for barter (and a network),
  • coins,
  • banknotes and
  • digital payments.

In order to reinvent America and extend its lifespan, Americans need to create new coins.

The quarter was invented in 1796.

It might be worth about $4 today.

So why not create a bronze-looking $5 coin with Abraham Lincoln’s image on it?

Lincoln is, after all, on the $5 bill.

Once that coin is minted, pennies, nickels and dimes can be eliminated.
