Warning! Machines are capable of self learning!

Gentle readers:
 I am an easygoing kind of person and it takes something serious to push me into writing warnings! I believe that machines with the ability to teach machines at super speed will lead to serious problems for the human race in the very near future. If that does not shake you up a little how about machines teaching themselves at lightning speed? Need more information? Read the following article. J.R. ---

“The easier it is to communicate, the faster change happens.” – James Burke, Science Historian
During an October 2015 press conference announcing the autopilot feature of the Tesla Model S, which allowed the car to drive semi-autonomously, Tesla CEO Elon Musk said each driver would become an “expert trainer” for every Model S. Each car could improve its own autonomous features by learning from its driver, but more significantly, when one Tesla learned from its own driver—that knowledge could then be shared with every other Tesla vehicle.
As Fred Lambert with Electrik reported shortly after, Model S owners noticed how quickly the car’s driverless features were improving. In one example, Teslas were taking incorrect early exits along highways, forcing their owners to manually steer the car along the correct route. After just a few weeks, owners noted the cars were no longer taking premature exits.
“I find it remarkable that it is improving this rapidly,” said one Tesla owner.
Intelligent systems, like those powered by the latest round of machine learning software, aren’t just getting smarter: they’re getting smarter faster. Understanding the rate at which these systems develop can be a particularly challenging part of navigating technological change.
Ray Kurzweil has written extensively on the gaps in human understanding between what he calls the “intuitive linear” view of technological change and the “exponential” rate of change now taking place. Almost two decades after writing the influential essay on what he calls “The Law of Accelerating Returns”—a theory of evolutionary change concerned with the speed at which systems improve over time—connected devices are now sharing knowledge between themselves, escalating the speed at which they improve.
“I think that this is perhaps the biggest exponential trend in AI,” said Hod Lipson, professor of mechanical engineering and data science at Columbia University, in a recent interview.
“All of the exponential technology trends have different ‘exponents,’” Lipson added. “But this one is potentially the biggest.”
According to Lipson, what we might call “machine teaching”—when devices communicate gained knowledge to one another—is a radical step up in the speed at which these systems improve.
“Sometimes it is cooperative, for example when one machine learns from another like a hive mind. But sometimes it is adversarial, like in an arms race between two systems playing chess against each other,” he said.
Lipson believes this way of developing AI is a big deal, in part, because it can bypass the need for training data.
“Data is the fuel of machine learning, but even for machines, some data is hard to get—it may be risky, slow, rare, or expensive. In those cases, machines can share experiences or create synthetic experiences for each other to augment or replace data. It turns out that this is not a minor effect, it actually is self-amplifying, and therefore exponential.”
Lipson sees the recent breakthrough from Google’s DeepMind, a project called AlphaGo Zero, as a stunning example of an AI learning without training data. Many are familiar with AlphaGo, the machine learning AI which became the world’s best Go a player after studying a massive training data-set comprised of millions of human Go moves. AlphaGo Zero, however, was able to beat even that Go-playing AI, simply by learning the rules of the game and playing by itself—no training data necessary. Then, just to show off, it beat the world’s best chess playing software after starting from scratch and training for only eight hours.
Now imagine thousands or more AlphaGo Zeroes instantaneously sharing their gained knowledge.
This isn’t just games though. Already, we’re seeing how it will have a major impact on the speed at which businesses can improve the performance of their devices.
One example is GE’s new industrial digital twin technology—a software simulation of a machine that models what is happening with the equipment. Think of it as a machine with its own self-image—which it can also share with technicians.
A steam turbine with a digital twin, for instance, can measure steam temperatures, rotor speeds, cold starts, and other data to predict breakdowns and warn technicians to prevent expensive repairs. The digital twins make these predictions by studying their own performance, but they also rely on models every other steam turbine has developed.
As machines begin to learn from their environments in new and powerful ways, their development is accelerated by communicating what they learn with each other. The collective intelligence of every GE turbine, spread across the planet, can accelerate each individual machine’s predictive ability. Where it may take one driverless car significant time to learn to navigate a particular city—one hundred driverless cars navigating that same city together, all sharing what they learn—can improve their algorithms in far less time.
As other AI-powered devices begin to leverage this shared knowledge transfer, we could see an even faster pace of development. So if you think things are developing quickly today, remember we’re only just getting started.

How to change your wrong beliefs. By Eric Barker

Changing These 4 Beliefs Will Make You Surprisingly Happy

Before we commence with the festivities, I wanted to thank everyone for helping my first book become a Wall Street Journal bestseller! To check it out, click here.

Traffic upsets you. People upset you. Your job upsets you... Wrong, wrong and wrong.

Actually, none of those things upset you. Your beliefs about them do. That's what the ancient Stoic philosophers believed.

From The Daily Stoic:

“People are not disturbed by things, but by the views they take of them.” – Epictetus

Let's say you expect something to cost $90. Turns out it costs $80. You're thrilled. But if you expect it to cost $30 and it costs $80, you want to murder someone. Price didn't change. Your belief did. And that determined your reaction.

Oh, and science agrees with the Stoics here. Big time. Albert Ellis was a psychologist and he took the ideas of the Stoics and weaponized them into some of the most effective therapies that professionals use today.

How big a deal was Albert? According to a survey of psychologists he was the 2nd most influential psychotherapist ever. Sigmund Freud came in third. Here’s what Wikipedia says about his system:

In general REBT is arguably one of the most investigated theories in the field of psychotherapy and a large amount of clinical experience and a substantial body of modern psychological research have validated and substantiated many of REBTs theoretical assumptions on personality and psychotherapy.

And Albert says your beliefs are what cause the majority of unhappiness, anger, and anxiety you experience. Problem is, some of these beliefs are sneaky.

You don’t even realize they're there. If I told you that you believed them, you'd deny it. But they're often dictating your reactions -- and making you miserable in the process.

So what are some of the most common problematic beliefs Albert identified – and how do we fix them?

Let's get to it...


#1: "This shouldn't be happening!"


This is the big one. Here's how Albert describes the #1 irrational belief we all too often hold:

"People and things should always turn out the way I want them to and if they don’t, it’s awful, terrible, and horrible, and that’s not fair."

Sounds ridiculous. You would never say that, right? Problem is, you often believe it without realizing it.

Say I tell you this toaster over here almost never works. You try to use the toaster. It doesn't work. Do you get furious and throw the toaster at me? No. Reality met expectations. No surprises. No emotional outburst. Now let's apply that same logic in a different scenario...

You know the world is not always a fair place, right? But then something unfair happens and... you go ballistic. Does that make sense? Nope.

If you really believed the world wasn't always fair and the world promptly delivered some unfairness, you wouldn't get all bent out of shape. Reality met expectations. But what you really believe is the world shouldn't be unfair to you. And that, my dear friend, is crazy talk.

Here's Albert:

We know the world is not fair, yet we still get overly upset when it’s unfair to us. We start thinking, very early on, that the world should be fair to us in particular... The “upsetness” doesn’t make the problem go away or solve anything (as a matter of fact, you probably make poorer decisions, and deal with others less effectively), but you don’t question your reaction because it seems so natural.

So how do you stop getting angry when life (which you acknowledge is unfair) does exactly what you said it would (and acts unfairly)? You need to change that underlying belief -- the one you didn't know you had.

Next time you find yourself getting upset, notice it. Pause. And then:
  • Identify the underlying belief: "Uh-oh. I'm believing that this unfair life must treat me fairly, aren't I?"
  • Dispute that belief: "Is this belief rational?" No. Uh-uh. No way, no how.
  • Replace the belief: So what's a more reasonable stance? "I would prefer to be treated fairly, but I know things aren't always going to be to my liking. I'm not surprised and I'm not going to lose my cool."
(To learn more about the science of a successful life, check out my bestselling book here.)

Okay, so outside events aren’t always gonna go your way and holding an underlying belief that is aligned with that can make life's ups and downs much easier to manage.

But what beliefs about your own behavior does Albert say regularly cause you problems?


#2: "I Must Be Perfect."


Here's how Albert describes it:

“I must not fail at important tasks and if I do it’s terrible and I can’t stand it.”

Again, you don't always realize this is your underlying belief. If I asked, "Are you human and prone to error?" You'd say yeah. But then you make a mistake and totally freak out. Does not compute.

If you really believed you were prone to error, you might be a little disappointed. You'd prefer to always get the A+. But you wouldn't be surprised and get overly emotional. Remember, you don't get angry when broken toasters act like broken toasters. You get angry when you expect broken toasters to act like working toasters.

And getting rid of your perfectionist beliefs doesn't mean you're suddenly going to become a slacker who half-asses everything. You can still be persistent. You just don't have to hold silly beliefs that drive you nuts. Here's Albert:

Searching for perfect solutions often will lead to stagnation and frustration. Perseverance, tolerance for less than perfection (but striving for it), the pursuit of improvement, and commitment to doing the very best you can, all are healthy, and most likely to yield the best results. Eliminating unreasonable demands for perfect solutions in no way reduces your commitment to doing or being the very best you can do or be.

And if that's not enough, research says perfectionism can kill you:

Consistent with our hypotheses, findings demonstrated that risk of death was significantly greater for high scorers in perfectionism and neuroticism, compared to low scorers at the time of base line.

So how do you deal with that pesky need to always be the best? Again, you have to dispute the underlying belief. Next time you're aiming for 110% and getting worked up, take notice.

Ask yourself if the belief is rational (nope) and replace it with something more realistic: "I'm going to work on the project for the next three hours and do my best. The amount of effort I expend is under my control but people's reaction to it isn't."

(To learn the seven-step morning ritual that will make you happy all day, click here.)

Okay, you're disputing and replacing irrational beliefs. Maybe you're not doing it perfectly at first -- but we don't have to be perfect, now do we?

So what about when that irrational belief is like a song stuck in your head? And you just cannot make it stop?


#3: "I Should Worry About This."


Here's Albert:

“If I worry obsessively about some up-coming event or how someone really feels about me things will actually turn out better.”

Ridiculous, right? But sometimes that's the belief we're really holding. We worry and worry and worry some more. And if we stop worrying, we beat ourselves up for not worrying enough. It's like we think anxiety is a magic spell that, if chanted constantly, will actually prevent the dreaded thing from happening.

For the record, it won't. And you already knew that. But if you believed it deep down, you wouldn't be biting your nails so much. Broken toaster theory all over again.

So how do you make the worry song stop playing in your head? You know the answer here: dispute and replace the belief. But with anxiety, it can be trickier because worry seems to operate on autopilot in the background. Time to bring out the big guns...

What is worrying? It's your brain's way of reminding you that something is a threat and needs to be dealt with. So what do you do if "dispute and replace" isn't cutting it in the short term? Let your brain know you're taking its reminders seriously.

Schedule your worrying. Seriously. Make a "worrying appointment." This works:

For those concerned with shedding some of their anxieties, it seems planning a certain time every day to worry may help stop the stress-out cycle. When people with adjustment disorders, burnout or severe work problems used techniques to confine their worrying to a single, scheduled 30- minute period each day, they were better able to cope with their problems, a new study by researchers in the Netherlands finds.

Please make sure to tell co-workers, "I'd love to go to that meeting but4PM is when I get all my worrying done for the day."

And don't just worry during the appointment  -- dispute and replace. With practice, the worries will subside. Behavioral therapies like this are the most scientifically proven treatments for anxiety.

So you can finally get that worry song to stop playing in your head. But how do we deal with those beliefs about our past that have shaped us? The beliefs that we feel make us who we are?


#4: "It's because of my past."


Albert explains the belief like this:

“It was my past and all the awful things that happened to me when I was a child or in my last relationship or in my last job that causes me to feel and act this way now.”

We make mistakes -- often the same ones over and over -- and we say it's due to bad parenting. Or because we were teased in high school. Or because we dated the wrong people.

Yes, Albert acknowledged some traumas do leave lasting issues. But many, many people willingly accept more minor past problems as part of their identity and don't really try to correct them. Here's Albert:

There is no question that our past experiences have the potential to influence greatly our present behavior, if we let them... Past events won’t become any less real or valid; we can’t change the tapes of those events. We can, however, vigorously change how we think about them.

In most cases it's not that the past event caused irrevocable damage; it's that you are presently carrying an irrational belief about yourself that you took away from the event.

"I was bullied in school because I was weaker than the other kids. So I am a weak person." And decades later you're still running that buggy old code like it was the latest software update. Yeah, you may have had moments of weakness in the 4th grade. Does that mean you're a weak person at 32?

Even though we've changed and our environment has changed, we cling to that outdated belief and it affects how we feel. Then confirmation bias kicks in and we stop noticing evidence to the contrary -- while maintaining a keen eye for everything that validates that irrational belief.

"I got nervous during that presentation today. It's because I'm a weak person. Yeah, I killed 37 ninjas with my bare hands on the way from the parking lot to the office this morning, but that was just dumb luck. I've always been weak and I'll always be weak."

From The CBT Toolbox: A Workbook for Clients and Clinicians:

Because of how our filters (beliefs) are set up, we often notice instances that support the unhealthy beliefs more than we notice those that may support our opposite, healthy beliefs; however, that “evidence” almost always exists as well.

So how do we fix this? Of course, dispute and replace. But this one can be tricky because of confirmation bias. We're only noticing and remembering the times when the irrational belief seems to be true (nervous during presentation) and not the times when it's proven false (single-handedly defeating hordes of expertly trained martial arts masters.) So you're gonna need some help with this disputing process.

Sit down with an old friend and a piece of paper. Make your case. Write down all the events that happened over the years that prove your irrational belief true. "I am weak because..."

When you're done, list all the events that contradict the belief. "I am not weak because..." And your friend gets to add to this list. You don't get veto power over their contributions. Remember, you're biased.

From The CBT Toolbox: A Workbook for Clients and Clinicians:

One valuable tool involves forcing ourselves to look back over those very same periods of life purposefully looking to see the evidence that supports our healthy beliefs. You may want to rely on family members or friends who were around during each period of life to help you “notice” such evidence. Even if they share things they see as “counting” that you don’t think “should count” write them down anyway...

If there is anything on the second list, then you are not cursed by your past forever -- you're cursed by an outdated belief that you still hold. Dispute and replace.

Are you weak at times? Probably. But that’s true of everyone. You’re human. Welcome to the party.

(To see the schedule that very successful people follow every day, clickhere.)

Okay, I now hold the underlying belief we've learned a lot about beliefs. Let's round it all up -- and learn the two words that signal you have some more disputin' and replacin' to do...


Sum Up


Here are the 4 irrational beliefs that cause you a lot of problems:
  • "This shouldn't be happening!": Do you really expect to always get what you want? No. But if you really believed that you wouldn't be shouting.
  • "I must be perfect.": Not possible. And it'll kill you. You can control effort, not outcome. "I will do my best" is rational. "I mustbe the best" is not.
  • "I should worry about this.": Set a time to worry, to dispute, and to replace. This lets your brain know it doesn't need to be reminding you 24/7.
  • "It's because of my past.": If that's really the case, then you should be in therapy. But your problems are rarely due to dire past traumas, they're usually due to some outdated, irrational belief you still hold. Get a friend to help you dispute and replace.
You may have noticed two words that came up again and again: "should" and "must." Albert Ellis hated those words. He felt they were at the core of so much of our emotional suffering.

Both imply that the universe needs to bend to your will. And that's not going to happen. "Prefer" all you like, but "should" and "must" are like shaking your fist at the sky when you don't like the weather. It "should" be sunny? Well, it's not.

When you align your expectations with reality, you stay cool like Fonzie. And then you're able to do something that might help you get what you "prefer."

Whenever you hear yourself saying "should" or "must", it's a sign you might be working off an irrational belief. Time to dispute and replace -- unless you like being unnecessarily stressed and angry. I don't.

So out of supreme respect for Albert, I'm not going to say you "should" or "must" obey the above advice...

But doing so will make you much happier. That's my underlying -- and very rational -- belief.

When facing nuclear armageddon, smile!

When facing nuclear Armageddon, smile!

Gentle People:

  In Hawaii recently somebody pushed a nuclear warning button and terrified the
population into a crazed panic. People had no where to hide!

 Apparently we have become much too comfortable with our so called nuclear deterrence philosophy and millions of us are not prepared to face the terrifying prospect of a quick death. Nuclear deterrence may work on normal people who have a healthy fear of death but when you are dealing with megalomaniacs or sociopaths or psychopath leaders who have gained with luck or heritage or subterfuge, enough economic and political and military power to dominate their own populations and then moment by moment threaten the world with nuclear Armageddon..your options for avoiding war and death become limited!

 One solution is to surgically remove insane leaders from power and replace them with clones who believe in Ethics and in protecting Human Rights as well as protecting and enhancing Nature. 
 Place the maniacs one by one into insane asylums where they can do no harm. Keep them alive and healthy but without any form of leadership controls and absolutely                 without access to nuclear missile fire and release buttons.
For recreation you can provide them with one purpose only deactivate-missile program games. Such games will allow them to destroy nuclear warheads and accumulate up to a Billion points which will count for their eventual release back into normal society.

 Also, and this is important, once in a while you have to visit a psychiatrist for a complete mental health check because if you succeed with the above plan, you have become a world leader.. Have a safe and happy life!
P.S.
If a nuclear missile comes your way, smile, there is nothing else you can do about it.

Wow! A possible fountain of youth in your head!


Brain Cells Found to Control Aging
Scientists at Albert Einstein College of Medicine have found that stem cells in the brain’s hypothalamus govern how fast aging occurs in the body. The finding, made in mice, could lead to new strategies for warding off age-related diseases and extending lifespan. The paper was published online in Nature.

The hypothalamus was known to regulate important processes including growth, development, reproduction and metabolism. In a 2013 Nature paper, Einstein researchers made the surprising finding that the hypothalamus also regulates aging throughout the body. Now, the scientists have pinpointed the cells in the hypothalamus that control aging: a tiny population of adult neural stem cells, which were known to be responsible for forming new brain neurons.

“Our research shows that the number of hypothalamic neural stem cells naturally declines over the life of the animal, and this decline accelerates aging,” says senior author Dongsheng Cai, M.D., Ph.D., professor of molecular pharmacology at Einstein. “But we also found that the effects of this loss are not irreversible. By replenishing these stem cells or the molecules they produce, it’s possible to slow and even reverse various aspects of aging throughout the body.”

In studying whether stem cells in the hypothalamus held the key to aging, the researchers first looked at the fate of those cells as healthy mice got older. The number of hypothalamic stem cells began to diminish when the animals reached about 10 months, which is several months before the usual signs of aging start appearing. “By old age—about two years of age in mice—most of those cells were gone,” says Dr. Cai.

The researchers next wanted to learn whether this progressive loss of stem cells was actually causing aging and was not just associated with it. So they observed what happened when they selectively disrupted the hypothalamic stem cells in middle-aged mice. “This disruption greatly accelerated aging compared with control mice, and those animals with disrupted stem cells died earlier than normal,” says Dr. Cai.

Could adding stem cells to the hypothalamus counteract aging? To answer that question, the researchers injected hypothalamic stem cells into the brains of middle-aged mice whose stem cells had been destroyed as well as into the brains of normal old mice. In both groups of animals, the treatment slowed or reversed various measures of aging.

Dr. Cai and his colleagues found that the hypothalamic stem cells appear to exert their anti-aging effects by releasing molecules called microRNAs (miRNAs). They are not involved in protein synthesis but instead play key roles in regulating gene expression. miRNAs are packaged inside tiny particles called exosomes, which hypothalamic stem cells release into the cerebrospinal fluid of mice.

The researchers extracted miRNA-containing exosomes from hypothalamic stem cells and injected them into the cerebrospinal fluid of two groups of mice: middle-aged mice whose hypothalamic stem cells had been destroyed and normal middle-aged mice. This treatment significantly slowed aging in both groups of animals as measured by tissue analysis and behavioral testing that involved assessing changes in the animals’ muscle endurance, coordination, social behavior and cognitive ability.

The researchers are now trying to identify the particular populations of microRNAs and perhaps other factors secreted by these stem cells that are responsible for these anti-aging effects—a first step toward possibly slowing the aging process and treating age-related diseases.
