Shrinking mind

Humanity has been on an unambiguous upward slope of expanding mind and psyche forever. Although there have been minor setbacks in the dark ages, humans have always been marching forward. Now there are good reasons to doubt if this will continue. Half the world population is now governed by charlatans and autocrats, some fraudulent and others heartless. There have been telltale signs of a bifurcating world, based on knowledge and empathy. There are now alternative universes, not the kind physicists think about, but simultaneous spaces with different information content existing in the same time coordinate. It appears that we are fast approaching a fork on the road and the selection of this binary choice could possibly seal the fate of humanity.

From dynamite to nuclear bombs, the inventors always lamented of their own accomplishments. There are good reasons for it. In a world of peaceful human beings, less than 0.000001% could substantially change the dreams and hopes of the rest. Some use weapons and others words to hurt the rest using the pulpit they have been granted. Humans remain to be in a level 0 society, still lacking a holistic understanding of what connects them together and their own irrelevance in a universe of inexplicable complexity. They seem to be saddled with a badly designed organ with high computing power but little capability in seeing and understanding the big picture. They have not been here before. For most of their history, they basked in uniformity - in color, ignorance, knowledge and capability. In the last few hundred years, they have been forced to intermingle but they still have to use hardware and operating systems designed for the past. Masking this with fancy applications has not been successful for a small percentage of the population.

It looks bleak. Educators may want to take note, millennials seem to have it, but the issue is they that may not have a chance.

Condensed knowledge

A recent study (1) that appears to demonstrate mining entire body of articles than abstracts provides higher information content is obvious. The more important question is what the mining is for and how the results are expected to be used. Also interesting is how much more incremental knowledge can be extracted from full articles.
 
In a world of exponentially expanding data, the risk of getting caught in the details is high. The “detail oriented technician,” has been more useful than those who see “the big picture,” in a scientific context because discoveries came from pouring over the data in a detailed fashion. But now, data is arriving from every direction and time is not an affordable luxury for decision-making and advancing ideas, with half-lives tending toward days and weeks.
 
Humans have not been here before. For hundred thousand years, they banked on experience, accumulated over many generations. Now, experience is losing out to machine learning. Here, time is of the essence and understanding patterns reigns supreme. Patterns have a hierarchical structure, and if a pyramid needs to be built bottoms up, it may not add value if it takes too long. Hyped up technologies in the areas of deep learning and mind will likely find that brute force approaches to “artificial general intelligence,” are unlikely to yield interesting results. 
 
The early human survivor in the wild had an intuition that the leopard is behind the bush to the left of her and she relied on patterns at the highest levels. Data scientists toiling with oceans of data, statistical modeling platforms, machine learning, deep learning and even deeper mind, may have to look back and understand that throwing data, analytics and technology at a problem, never helped humanity.

Fusion deficient

Humans' ability to harness energy, propelled tactically by the Sun, remain meager. Unfortunately, they have not even been able to replicate the processes in the Sun that apparently throws of seemingly unlimited free energy. Fusion, hot and cold, eluded the struggling species, with nearly 30% still without proper food, clothing and shelter. Lifting humanity from despair remains to be an energy problem, something not many are focused on.

The simplest of processes, fusing two Hydrogen atoms into one of Helium and releasing an abundance of energy, still remains outside the grasp of the engineers. Recent news from the famous defense contractor was encouraging but the path to practical implementation still seems too long. And the crooks who raised false hope on cold fusion seem to have gone away. Tactical conversion of Sun's power - solar and wind - still seem too expensive and rather cumbersome. And, if the energy secretary ever goes to school and perhaps learn something, he may learn that fossil fuel is not the answer either.

The answer appears to be tantalizingly close in fusion. The template is readily available and a generation of great technologists stand ready to convert dreams into practical applications. What is missing is imagination, something that cannot be taught or bought. Perhaps, we need a bit of luck.

The code

Humans and their cousins, the apes, have been exceptional in facial recognition. Their life depended on it for the ability to recognize a friend from a foe was crucial for survival. Recent research from Caltech (1) appears to get closer to the neural code for face recognition. The trick appears to be specialization with singular neurons, focused on specific features. The idea appears to validate recent advances in deep learning for image recognition and it could provide further impetus to the acceleration of artificial intelligence.

The idea that single neurons encode specific features has been tantalizing for deep learning enthusiasts. It allows scalability in deep neural networks with increasing specialization in layers. The single feature specificity at the neuron level and its ability to make binary decisions provide further evidence of micro compartmentalization and voting based decision-making. Complementarity, communication and cooperation appear to dominate in goal seeking and that has implications for future research in computerized image recognition and more broadly, artificial intelligence.

The neural code developed by primates, an efficient and massively parallel processed algorithm that helped them survive and evolve, could be replicatable. Hopefully, those who get hold of this will use it wisely.

The DART

The space administration's plans to throw a refrigerator at an incoming small asteroid (1) to demonstrate fancifully worded, "kinetic impactor technique," is ample proof that humans are sitting ducks on the blue planet surrounded by big and fast objects. Momentum has been known for a while and if one can impact the direction of the approaching object slightly, it could be beneficial. But to be effective, such a maneuver has to be very early in the trajectory of the approaching object. Combined with a lack of knowledge of projectiles moving toward us, it remains to be a probability game - and the odds are likely against the species, still trying to kill each other around the world.


If the state of the art is studying the effect of an impact of a heavy projectile on an approaching asteroid, it seems that we have not advanced sufficiently to survive. If the best minds in practical space exploration are engaged in tactics, we may be in more terrible shape than could be imagined. Aided by policy making ignoramuses in the capitol, trying to cut funding for fundamental research, we now have a stagnant knowledge regime, unable to advance science and humanity. To make matters worse, we have engineers and technologists focused on applying old ideas just to win funding. 


Stupidity has a price. In most past failed experiments in civilizations, it ended up with an ignorant leader perpetuating tactics surrounded by those currying for favor by applying old ideas to solve new problems.

The quantum phone call

Ever since the phenomenon of entanglement was discovered, humans have been enthralled by visions of communication at faster than the speed of light. Recent experiments with the Micius satellite (1) appear to move us closer to practical satellite based quantum communication. Bringing entanglement to applications could propel humanity to a different level.


Humans have been constrained optimizers. From inception, they have been prisoners of space and time. Their ability to physically transport their inelegant bodies has been inferior to most animals that surround them and their inability to see for half the day, made them vulnerable. Later, they will find that they cannot communicate faster than the speed of light and they cannot travel faster than a fraction of this theoretical limit. To make matters worse, they were greeted by silence in close quarters, albeit their space broadcasting and listening methods, remain embarrassingly archaic. Humans remain to be prisoners of space and time and it appears that it would be forever.


Entanglement provides a mild hope out of these hard constraints. Beating light can lift the spirits of humans and open up the universe that largely remains unapproachable.

The autoimmune era

Humans, it appears, have successfully conquered external biological threats to them, at least in the short run. One implication of this dominance is the alarming rise of autoimmune diseases that now account for most of the healthcare costs. Their finely tuned and powerful immune system has become a great liability for the modern humans, devoid of bugs. Boredom of overdesigned systems appear to be as deadly as anything else. Recent discovery of rare diseases in which the immune system attacks the brain itself is a constant reminder that the biggest threat for humans in the long run is their own immune systems.
 
Heart disease, cancer, mental disorders, COPD, asthma, arthritis, diabetes and hypertension account for over 80% of the healthcare costs. The bugs are not implicated in any and it appears that the body has begun to attack itself. Original design deficiencies in Homo sapiens have certainly caught up with them. The plumbing was never designed to last more than a few decades and the body, now stretched to twice the original design life, seems to struggle to get rid of the waste products both in the brain and in the circulation systems. To make matters worse, humans invented agriculture recently and this has fundamentally changed the course of their health. They have been feeding themselves material that neither the body nor the bacteria in their guts have ever been designed to efficiently digest.
 
We are in the autoimmune era, in which most humans will die because of the efficiency of their immune systems or the inability of the circulations systems to discharge waste products. Medicine and Engineering are certainly converging, but not in a way that technologists imagined.

Artificially Intelligent Pain

Recent observations (1) from the University of Cambridge that machine learning could identify the amount of pain suffered by sheep from their facial expressions is a good tangent to pursue. It may even have applications in humans, unable to communicate because of  recent or permanent loss of auditory and visual functions. Machines have been growing in stature and they seem to trump humans in most routine tasks. But increasingly, they are filling the gaps that humans are unable or untrained to do. There is no turning back from the AI train as it had left the station nearly 3 decades ago. Now cheaper and faster computers are making what could not be done by pure imagination.


On the other hand, humans generally get over-excited about emerging technologies and they believe problems could be solved in the matter of months, if not, days. Often, they have been wrong and many examples are available, in air travel, the internet, human genome based medicines and most recently, machine learning. Humans have been slow leaners, in spite of the massive energy hog they have been endowed with and they are programmed to look to the future rather than the past. That is a good thing but looking too far and over the hills may get them into trouble, something that did not exist for most of their evolution.


Understanding pain from facial expressions is a good step forward but a 67% accuracy (1) is not sufficiently robust for practical applications. Machine learning can easily create models of that accuracy from random and noisy data. Before declaring victory, much work is in store to think about what it could mean.

Vancomycin 3.0 - The fight continues

Recent news (1) that a new breed of antibiotics, possibly many orders of higher potency than what is currently available, is entering the fight against the Earth's oldest inhabitants, could be welcome news for extension of life for humans. However, the long term implications of such leapfrogs remain uncertain. Bacteria, the most robust form of life known, have been fighting and improving for nearly 4 billion years. The upstarts, humans, seem to have turned them back incrementally. But the aggregate number of evolutionary experiments possible matter and here, the single cell organism reign supreme and for ever.

Bacteria have crowded out the human gut and they supply a large number of genes incorporated into the human architecture. There has been some evidence that bacteria control the human brain from the gut using nerve ends and they have occasionally even breached the blood-brain barrier. The original Extra-terrestrials have been potent and high achieving, seemingly able to dominate anything thrown their way. They even dance in unison and communicate by telepathy, notions higher order animals, find hard to appreciate. Lack of sight and biases helped them cooperate across species and evolve into the most dominant life form on Earth.

The winner of this race is predetermined as the early arrivals to the blue planet have captured the soul and imagination of the irrelevant speck in the universe.

Sleep discrimination

A recent study (1) concludes that the world is heading toward sleepless nights with climate change driving temperatures up. A mere 1 degree temperature rise at night could result in a 10% loss in sleep. This is a problematic trend, with a skewed impact on the poor who can't afford air conditioning. More importantly, loss of sleep has significant deleterious effects on health and cognition, with possible broad impacts on students and young adults. This is another reminder that changes in the environment could have negative effects on the population in many different ways. Anything that affects the rapid progression of millennials is not something humanity could afford, at this critical juncture, if they were to leap to a level 1 society.


As they ventured out of Africa, humans encountered harsh winters in the North with their systems adjusting rapidly by changes in skin and hair colors. Those who went South had an easier time and appear to be well positioned for the rising temperatures of the modern world. However, the organ they carry on their shoulders hogs energy and has to be kept cool for them to slumber. A rise in the ambient temperature is problematic for the human system and especially for the CPU. Perhaps, it is time for newer technologies that let a cooler bubble around the human brain. Evolution of the human brain has been slow. Massive leaps achieved a few hundred thousand years ago by animal fat have been tempered significantly by the advent of agriculture. And, modern humans appear to show slow degradation of cognitive capabilities, perhaps aided by substance abuse.


It is unlikely that humans can turn back the temperature dial but perhaps they can find more creative ways to cool the brain cells and sleep better.

Tactical valley of ignorance

Many of the rich and famous appear to be now indicating that universal income (1) is a good policy. It may be too little too late with children running powerful nations and corporations. If they do want to make an impact, it will take more than speeches and photo ops. It will require actions to disseminate information across populations and technologies that can curb misinformation. It will require belief and the ability to embrace a utility function that encompasses humanity.

There are good signs for humanity, however. Bad examples have great value in education and we certainly have a great number of them in full display. But education is a necessary condition that will allow humanity to separate the wheat from the chaff, those who have been marginalized and the lucky, those who volunteer to make the world better and the uninterested, the unlucky from those who fight for money, the rebels from those who appear religious, the travellers from those who stay put, the indifferent from those who seek their own kind, the optimizers from those who maximize, the elderly from those who do not grow up.

We are slowly progressing toward a better society. The hiccups on the way are just that and contemporary events may provide rich fodder for comedy shows in a few decades. The millennials appear to have it but they have to get through a tactical valley of ignorance.

Immigrants

Nearly 3% of the population - 250 million, live outside the country of their birth (1) and it is a constant reminder that humans have been on the move for over 100 thousand years. They spread culture, ideas and biases across locations and continents, eliminated those who differ from them and clung together to survive in the bottleneck that reduced them to a few thousand. In spite of the walls that separated them, they pushed to assimilate in spite of the color of their skin, eyes or hair, and now we may be turning time back for the worse.


Knowledge has always slowed down the journey to destruction and those who did not imbibe from the fountain have been left behind to fend for themselves. Geographical segmentation schemes have separated siblings and illogical religious constructs have united those who never wanted to be united. Humans have separated themselves based on surface features, never considering that their architecture has been a lot deeper. As they shut down the boundaries of their recent homes based on ignorance, the intelligentsia bleeds but as they always do, they remain ineffective.


Move, move again - and let humanity come together, once again.

The advantages of sex

A recent study (1) suggests that genetic interactions are driving selection. This is an important finding and it suggests that mutations are not sufficiently robust to propel populations to more dominant states. In fact, mutations may have a negative effect on optimal progression. It has major policy implications in that, if humanity were to survive, it would be largely driven by genetic interactions rather than optimization in sub-populations.
 
Humans seem to be on a dangerous course, propelled by an affinity to surface features and segmented utility. The leaders in most countries appear to be less intelligent than average and it implies suboptimal policies with long term deleterious effects. As they travelled out of Africa by foot, first to Australasia and then to China, they never imagined the state of affairs, they would find themselves in fifty thousand years later. Some travelled north and obliterated the gentle Neanderthals and some stayed put, only to be marginalized. Some crossed the ice bridge into the new continent only to be separated from the rest.
 
Without an abundance of genetic interactions, humans are doomed to oblivion. Fortunately, the idiots who run countries and corporations have a limited life span.

Pinnacle

At the pinnacle of innovation, technology and war mongering, those who are climbing it seem to have left behind nearly ten million of their exact copies in Nigeria, with half of them malnourished and failing from diseases, amplified by hunger (1). For a societal leap forward, it will require moving the entire humanity to a position of sustenance. Empathy has been easier than effective policies, tweets easier than action, cosmetics and shallow conversations easier than thoughts and ignorance safer than seeking knowledge. Meanwhile, millions perish from lack of basic necessities.
 
The question remains to be why humanity is stuck in this local minimum. Good has always trumped the bad and ideas flourish over stagnation, but it appears that we are unable to break out of a stalemate, aided by global apathy and instability. Societal progress has been immensely hampered by illogical constructs such as an outward show of religion and patriotism. Those who could aid a move up from the valley have been busy nourishing their egos in academia and fighting their colleagues. Those who want to save the world by elevating themselves to the top of the hierarchy have been corrupt and emotionless. At the heart of this stalemate is lack of education, as ignorance has spread like wildfire across the world, aided and abetted by their leaders. If the 7.6 billion occupying the world only knew that they are clones of a single human being, perhaps we can begin to bridge the gap.
 
But it is a tall order as humans suffer from myopia, driven by hard constraints on life span.

The bulge in the frontal cortex

Recent finding in the Journal of Neurological Sciences (1) that Descartes' brain had an unusual bulge in the frontal cortex is further proof that humans with unusual developments in the organ they carry on their shoulders, move societies. Less than a hundred individuals with such deformities in the last two thousand years, including Albert Einstein, substantially contributed to most knowledge accumulated by humans. This implies that knowledge is a result of unusual patterns in the brain and humans in general are not really designed to go a lot further than the basic attributes in their objective function, largely driven by food and reproduction.

Understanding their limitations is a leap forward for humans as their forward momentum depends largely on the arrival of the next genius. There has not been a positive sign in the last hundred years as they move technology forward at the destruction of the delicate greenhouse they have been afforded. As they travel to nearby planets, extend life incrementally and double computing power every 18 months, they have to realize that none of these have any fundamental impact on knowledge. For that, humans still require a major deformity in the brain of one of the billions of specimens they seem to have replicated into.

As indicated in the article (1) " It is not enough to have a good mind, the main thing is to use it well."

Faking news

Recent news that an unvaccinated Portuguese girl has died of measles (1) is a constant reminder that ignorance can exact a high cost. A single individual with a fraudulent study (2) may have caused humanity, a high level of disutility. Humans often fall prey to small N experiments and it further reinforces the need to eradicate ignorance.


Humans have always been susceptible to small experiment bias. However, small experiments may have played a substantial role in human progression. If the outcomes are of very high probability, small experiments may have been sufficient to learn - such as taking the right run at the fork, gets you killed by the waiting lion. A few experiments may have been sufficient to establish truth in this case. However, to prove that vaccination causes autism takes a few more than a dozen.


Education systems around the world may have to incorporate a better understanding of statistics into their curriculum. Understanding that truth is not revealed by one or few experiments is important and that may allow large swaths of the world population to get over "fake news." Faking news has become a strategic weapon. If a population is susceptible to believing what they see or hear, without asking for proof, ignorance will unambiguously rise to the top and that could have unpredictable negative effects on society.


Education has to evolve appropriately to add value to society.

Stuck in a quantum state

Development of life over the past few billion years on Earth shows few regime changes and evolution has been largely an incremental process. The organizing principle has remained the same from the inception of life till now - from a single cell entity to larger accumulation of the same in more specialized life. The objective functions remained simple with only a handful of attributes and optimization has been trivial. Extrapolation of the status-quo seems to imply that life on Earth is stuck in a quantum state and seemingly for ever.
 
Some have been dissatisfied with the overall progress of societal structure and organization. Academics and philosophers have proposed alternatives to enhance aggregate societal utility, largely by redistribution and reorganization. But they seem to miss a more fundamental issue - societies cannot transverse quantum states incrementally. To propel to the next quantum state, contemporary societies need a technology discontinuity, likely in the realm of energy. To make this happen, knowledge has to increase exponentially but in level 0, there appears to be a hard cap on knowledge.
 
If level 1 societies exist elsewhere in the universe, they would certainly have mastered energy as there appears to be plenty, freely available. With zero cost energy, such societies could organize around fully networked thoughts and transport modalities. Organization would be automatically optimal with a singular, albeit complex, objective function of the network rather than that of the individual. If it were to progress further, then the scope could be extended across universes and that would require another step-function change.
 
Humans seem to have approached societal design and optimization with a set of wrong assumptions. Visions of a level 1 society are not useful in thinking about optimality in the current state. A more practical question is what could be achieved in contemporary societies. Evidence shows free markets with well defined rules of engagement that apply equally to all participants move societies closer to an optimal state. However, humans have segregated themselves into countries, religions, languages, size and color and they pose hard constraints on free markets. With localized optimization dominating policy, we may be rewinding time back and destroying the precious little that was accomplished in the last ten thousand years.
 
Thought experiments that portray level 1 societies are useful abstract notions but with little practical utility. If 4 billion years do not show a slope that will get earthlings to the next quantum state, it is unlikely. Then, the real question is how to best utilize the limited time afforded to the blue planet in a state that cannot be breached.

Back to Europa

ET experts at the space agency have been focused on exoplanets for several years. After the proclamation that ET would arrive by 2020, there have been increased activities on multiple fronts. It has been known for a while that both Europa (Jupiter’s moon) and Enceladus (Saturn’s moon) harbor vast oceans and energy sources underneath their barren surfaces. As exoplanets similar to the Earth began to show up across the Milky Way, the ET enthusiasts seem to have taken their eye off possible habitats in their neighborhood.

Now that the space agency has determined that the probability of contact of green men at an exoplanet by 2020, whether it is the “exact twin,” of mother Earth, is small, they are back on neighborhood prowl and that may be a good thing. If humans were ever going to make “contact,” it could only be with the micro-organisms in Europa or Enceladus. However, as the space agency, on a binge of crashing space probes through the pristine atmospheres of these moons, have to be careful not to contaminate the oceans in these habitats. Otherwise, they may just find Salmonella there and declare victory. The process of sterilization has not been good and it is unclear if any of the single cell organisms that hitched rides on spacecrafts, used in interplanetary missions, is setting up colonies  in those planets before the mighty human gets there.

More importantly, in spite of the somewhat suspect sterilization regimen, if the space agency fails to find life in Europa and Enceladus, one has to wonder what it means. So far, most ET hunters have argued that it does not mean anything, for there are trillions of possibilities out there. That is true, but there is no free lunch in the absence of infinite resources. If no Salmonella was found in Europa and Enceladus, it may be time to take a break from ET hunting and focus on more mundane things such as protecting the Earth from an asteroid impact.

Extra-terrestrials appear not have a great desire to make contact with humans and I wonder why?

Living on luck

In a couple of weeks, an asteroid of nearly a kilometer wide will pass by the blue planet at just a million miles away, a mere whisker by any measurement. As the "leaders" throw hand grenades at each other, few have understood the precarious position their habitat is in. Reducing emissions to protect the environment is great, attempting to save it from instantly evaporating could be a bit better. Humans, carrying a heavy organ on their shoulders, seem to have wasted hundred thousand years, proving to themselves they are great and if not, thinking how to make them great again.
 
It is a miracle that the world survived in this active shooting gallery. Nothing much has happened since the first rulers of the planet were wiped out 65 million years ago by a massive event. And, the probability of that happening again is close to 1. As space agencies clamor to travel to nearby planets, just to demonstrate they are capable or design rockets that can take large and diverse payloads, they have to understand that none of these ego boosting triviality, will save humanity. As the most "intelligent" private investors, design, redesign and reuse rockets, as if that is the end game, they have to understand that there is a higher order problem to solve. Moving deck chairs on the titanic, optimizing how many chairs to move from one side to another or even creating a "game," that allows such movements to be automatic, is not going to be helpful at the face of calamity.
 
It will be ironic if the "greatest species," get wiped out by a similar event that happened before. At least the previous greats did not know it was coming.

Quantum optimization

Classical annealing has been a method of optimization in many areas, for ever. Recently, quantum annealing, based on quantum tunneling, was proposed as an improved process. Challenges remain (1), however, as qbits are immensely limited to make anything practical. The most profitable path to knowledge, at the intersection of quantum mechanics and optimization, may be breaking open. Flux quantization, as the authors argue, may allow us to tackle complex optimization problems.


It is clear that humans have been stagnant in the advancement of mathematics. At the intersection of theoretical physics and mathematics, there is a beautiful avenue to knowledge, something that has been less travelled in. There, determinism takes a back seat and probabilistic speculation dominates. Those who want interplanetary travel are simply leaving the movie theater before the show is over and it is possible that the few brain cells left to humanity could, indeed, take a quantum leap.


Humans wanted to always optimize as it has been ingrained in their structure from the moment they started to explore. They wanted to minimize distances and maximize the probability of a killing or analogously, minimize the probability of being killed. Ingrained in their quantum limited brain is the concept of optimization and now we could possibly take it further. In this context, it is important to remain humble as many before us have thought they indeed optimized, only to realize that there were many attributes beyond the equation that was used.


Flux quantization could provide a path forward to optimization but it is important to keep in mind that we have been here many times before.

Hubble Trouble (1)

Hubble, from the University of Chicago, observed for the first time in 1929 that galaxies are flying away from us. Many candles later, the constant attributed to his name, is still being refined. Now, it appears that there is a revision to the constant, perhaps as much as 8% downward. This is not the first time physicists realized that they are yet to understand how things work. Complexity typically portends lack of understanding and the current state of affairs in high energy physics, albeit data emanating from big steel in Geneva like water from a faulty fire hydrant, is stagnant. Physicists and engineers are a dangerous combination, the former dreaming up complexity and the latter standing ready to prove anything thrown at them by steel and concrete. But this is unlikely to lead anywhere. It appears that one does have to have 1.5 brains to break out of the stalemate - and we have not had a specimen for 100 years and it is unclear if we will ever do.


Predicting the behavior of complex non-linear systems is dangerous. Making uncertain observations and attempting to prove those by creating dark stuff is even more dangerous, for this will lead the next generation down rabbit holes to the wonderland. Hanging mirrors to measure reverberations to the diameter of a proton, indeed, is a great accomplishment. But one has to note that engineers have always been good at proving hypotheses but replicability could be more challenging. The best way to proceed when one cannot understand over 94% of the observations is to ask if the underlying theories are correct. That's what we do in most fields.


As they revise the Hubble constant, perhaps, it is time to rethink how research is done in high energy Physics.
