Deadly cocktail

The value of waiting to make an irreversible decision is intuitively clear to most thinking humans but it is likely too much to ask of politicians, even those who are not politically astute. Business and finance schools have been graduating stars who descend on Wall Street, consulting firms and corporate board rooms with a tool box that is mostly useless in aiding decisions. The same are now advising those with little understanding of the impact of their utterings and decisions and it is a cocktail of ignorance, arrogance, and shortsightedness that puts humanity at great risk.

It has been predictable for a while. Part of the blame has to go to educational institutions who have been clinging to age old ideas of economic value and optimality in decisions. The concepts were developed for companies thriving in a regime of manufacturing and the reluctance to let go of old ideas have costed both the academics and their disciples dearly. And to make matters worse, the ones in power seem to think that they are in the know just because they got branded. It is not so, just the opposite. In corporate finance, for example, unless one can publish within established notions of value and risk, it is tough going. And the crop of the young academics, trained in empiricism, have been toiling with their spreadsheets to prove what they know are incorrect theories. So, it is not innovation that matters but the ability to perpetuate the status-quo. Most do not seem to understand that we do not make widgets anymore and the ideas applicable there are not relevant for an environment driven by uncertainty and flexibility.

There has to be a basic test of competence before anybody can take a decision-making position, companies and countries included. The same has to be true in academics also and the fact that the "peers," accepted established notions proposed by those who are rising is not an automatic reason for tenure. It is a shame that politics and academics share many common features.

Memory

Memory has been a dual edged sword for humans; they benefited from it by accumulating experience but often they suffered from it as well with pain dominating pleasure in the unknown chambers of the mysterious organ. Little has been known about the processes that support memory and the crude attempts at equating human memory to those of silicon based idiot boxes only took the scientists away from the truth. The selection advantages of memory are clear; it clearly reduced the probability of being eaten in the African Savannah. In the modern context, however, memory is not necessarily a good. It creates two problems; first, it nourishes biases based on extreme events, both positive and negative and second, it erects an unassailable wall to climb out of pain and tribulation.

At the abstract level, one has to wonder why humans remember. It did help them identify those from other clans by pattern finding, a good application of memory. But for those who have surpassed the clan regime, memory is not necessarily a benefit. Memory appears to be useful to find connections among uncertain and complex data but now, computers are getting a lot better at this task. If machines reach superiority over humans on pattern finding, the need for human memory will decline. The disutility of memory is in plain view for a species constrained by space, time and fleeting emotions. Faced by a hard life span constraint, they have been accumulating pain and often seek to alleviate it by physical means. The efficiency of the brain to store unpleasant episodes with high detail has led to diseases causing both mental and physical impairment.

A beautiful organ that combines chemistry, physics, and biology has marvelled everybody who attempted an examination of it. But then, design and architecture are not that interesting if the final product is not utility maximizing.

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.
