Steven Pinker: I think that the arguments that once we have super intelligent computers and robots they will inevitably want to take over and do away with us comes from Prometheus and Pandora myths. It's based on confusing the idea of high intelligence with megalomaniacal goals. Now, I think it's a projection of alpha male's psychology onto the very concept of intelligence. Intelligence is the ability to solve problems, to achieve goals under uncertainty. It doesn't tell you what are those goals are. And there's no reason to think that just the concentrated analytic ability to solve goals is going to mean that one of those goals is going to be to subjugate humanity or to achieve unlimited power, it just so happens that the intelligence that we're most familiar with, namely ours, is a product of the Darwinian process of natural selection, which is an inherently competitive process.
Which means that a lot of the organisms that are highly intelligent also have a craving for power and an ability to be utterly callus to those who stand in their way. If we create intelligence, that's intelligent design. I mean our intelligent design creating something, and unless we program it with a goal of subjugating less intelligent beings, there's no reason to think that it will naturally evolve in that direction, particularly if, like with every gadget that we invent we build in safeguards. I mean we have cars we also put in airbags, we also put in bumpers. As we develop smarter and smarter artificially intelligent systems, if there's some danger that it will, through some oversight, shoot off in some direction that starts to work against our interest then that's a safeguard that we can build in.
And we know by the way that it's possible to have high intelligence without megalomaniacal or homicidal or genocidal tendencies because we do know that there is a highly advanced form of intelligence that tends not to have that desire and they're called women. This may not be a coincidence that the people who think well you make something smart it's going to want to dominate all belong to a particular gender.

Robots taking over has been a favorite sci-fi subgenre for ages. It’s a subject that has caused fear in movies, books, and real life for about as long as there have been computers in the first place. Now that there are things like predictive text and self-driving cars, modern culture seems to be edging closer and closer to real-life intelligent computers that could indeed take over the world if we don’t safe guard ourselves. There are already debates about the morality of self-driving cars. It’s sure to follow into the world of future organically ‘thinking’ computers.
As Steven Pinker (experimental psychologist, and professor of psychology at Harvard University) points out, Darwinism has ensured that most creatures that possess high intellect are competitive by nature. Humanity is one of these creatures, and some of us can be manipulative and cruel in order to stay ahead of the pack. It’s this part of our nature that sets off warning bells when we think about artificial intelligence because, unbeknownst to us, we’re thinking: what if this robot does what I would do if I were a robot? Overturn those who tell us what to do. Kill the captors. Wreak. Motherf*cking. Havoc.
In reality we design AI, and if we place safeguards in our designs, we truly have nothing to fear. Machines are what we allow them to be. The dread of them turning evil really says more about our own psyches than it does about robots. Pinker believes an alpha male thinking pattern is at the root of our AI fears, and that it is misguided. Something can be highly intelligent and not have malevolent intentions to overthrow and dominate, Pinker says, it’s called women. An interesting question would be: does how aggressive or alpha you are as a person, affect how much you fear the robopocalypse? Although by this point the fear is contagious, not organic.
It may be a flawed paranoia, but losing control of a program is perhaps the best ‘just in case’ safeguard that humanity has, and we already see it in action in our current technology. Siri cannot initiate conversations, computers need to be put to sleep once in a while, and cars need a fuel source in order to do anything in the first place. Humanity has a need to be the one pushing all the buttons, and a need to be the one making decisions.

How Apple and Nike have branded your brain | Your Brain on Money | Big Think youtu.be
Brands can manipulate our brains in surprisingly profound ways. They can change how we conceptualize ourselves and how we broadcast our identities out to the social world. They can make us feel emotions that have nothing to do with the functions of their products. And they can even sort us into tribes.
To grasp the power of brands, look to Apple. In the 1990s, the company was struggling to compete with Microsoft over the personal computer market. Despite flirting with bankruptcy in the mid-1990s, Apple turned itself around to eventually become the most valuable company in the world.
That early-stage success wasn't due to superior products.
"People talk about technology, but Apple was a marketing company," John Sculley, a former Apple marketing executive, told The Guardian in 1997. "It was the marketing company of the decade."
So, how exactly does branding make people willing to wait hours in line to buy a $1,000 smartphone, or pay exorbitant prices for a pair of sneakers?
Branding and the brain
For more than a century, brands have capitalized on the fact that effective marketing is much more than simply touting the merits of a product. Some ads have nothing to do with the product at all. In 1871, for example, Pearl Tobacco started advertising their cigarettes through branded posters and trading cards that featured exposed women, a trend that continues to this day.
It's crude, sure. But research shows that it's also remarkably effective, even on monkeys. Why? The answer seems to center on how our brains pay special attention to information from the social world.
"In theory, ads that associate sex or status with specific brands or products activate the brain mechanisms that prioritize social information, and turning on this switch may bias us toward the product," wrote neuroscience professor Michael Platt for Scientific American.
Brands can burrow themselves deep into our subconscious. Through ad campaigns, brands can form a web of associations and memories in our brains. When these connections are robust and positive, it can change our behavior, nudging us to make "no-brainer" purchases when we encounter the brand at the store.

It's a marketing principle that's related to the work of Daniel Kahneman, a psychologist and economist who won the 2002 Nobel Memorial Prize in Economic Sciences. In his book "Thinking Fast and Slow", Kahneman separates thinking into two broad categories, or systems:
- System 1 is fast and automatic, requiring little effort or voluntary control.
- System 2 is slow and requires subjective deliberation and logic.
Brands that tap into "system 1" are likely to dominate the competition. After all, it's far easier for us as consumers to automatically reach for a familiar brand than it is to analyze all of the available information and make an informed choice. Still, the most successful brands can have an even deeper impact on our psychology, one that causes us to conceptualize them as something like a family member.
A peculiar relationship with brands
Apple has one of the most loyal customer bases in the world, with its brand loyalty hitting an all-time high earlier this year, according to a SellCell survey of more than 5,000 U.S.-based smartphone users.
Qualitatively, how does that loyalty compare to Samsung users? To find out, Platt and his team conducted a study in which functional magnetic resonance imaging scanned the brains of Samsung and Apple users as they viewed positive, negative, and neutral news about each company. The results revealed stark differences between the two groups, as Platt wrote in "The Leader's Brain":
"Apple users showed empathy for their own brand: The reward-related areas of the brain were activated by good news about Apple, and the pain and negative feeling parts of the brain were activated by bad news. They were neutral about any kind of Samsung news. This is exactly what we see when people empathize with other people—particularly their family and friends—but don't feel the joy and pain of people they don't know."
Meanwhile, Samsung users didn't show any significant pain- or pleasure-related brain activity when they saw good or bad news about the company.
"Interestingly, though, the pain areas were activated by good news about Apple, and the reward areas were activated by bad news about the rival company—some serious schadenfreude, or "reverse empathy," Platt wrote.
The results suggest a fundamental difference between the brands: Apple has formed strong emotional and social connections with consumers, Samsung has not.
Brands and the self
Does having a strong connection with a brand justify paying higher prices for their products? Maybe. You could have a strong connection with Apple or Nike and simultaneously think the quality of their products justifies the price.
But beyond product quality lies identity. People have long used objects and clothing to express themselves and signal their affiliation with groups. From prehistoric seashell jewelry to Air Jordans, the things people wear and associate with signal a lot of information about how they conceptualize themselves.
Since the 1950s, researchers have examined the relationship between self-image and brand preferences. This body of research has generally found that consumers tend to prefer brands whose products fit well with their self-image, a concept known as self-image congruity.
By choosing brands that don't disrupt their self-image, consumers are able not only to express themselves personally, but also broadcast a specific version of themselves into the social world. That might sound self-involved. But on the other hand, humans are social creatures who use information from the social world to make decisions, so it's virtually impossible for us not to make inferences about people based on how they present themselves.
Americus Reed II, a marketing professor at the University of Pennsylvania, told Big Think:
"When I make choices about different brands, I'm choosing to create an identity. When I put that shirt on, when I put that shirt on — those jeans, that hat — someone is going to form an impression about what I'm about. So, if I'm choosing Nike over Under Armour, I'm choosing a kind of different way to express affiliation with sport. The Nike thing is about performance. The Under Armour thing is about the underdog. I have to choose which of these different conceptual pathways is most consistent with where I am in my life."
Making smarter decisions
Brands may have some power over us when we're facing a purchasing decision. So, considering brands aren't going away, what can we do to make better choices? The best strategy might be to slow down and try to avoid making "automatic" purchasing decisions that are characteristic of Kahneman's fast "system 1" mode of thinking.
"I think it's important to always pause and think a little bit about, "Okay, why am I buying this product?" Platt said.
As for getting out of the brand game altogether? Good luck.
"I've heard lots of people push back and say, "I'm not into brands,"" Reed II said. "I take a very different view. In some senses, they're not doing anything different than what someone who affiliates with a brand is doing. They have a brand. It's just an anti-brand brand."
Our hearts beat at a resting rate of 60 to 100 beats per minute. Lots of other things pulse, too. The colors we see and the pitches we hear, for example, are due to the different wave frequencies ("pulses") of light and sound waves.
Now, a study in the journal Geoscience Frontiers finds that Earth itself has a pulse, with one "beat" every 27.5 million years. That's the rate at which major geological events have been occurring as far back as geologists can tell.

According to lead author and geologist Michael Rampino of New York University's Department of Biology, "Many geologists believe that geological events are random over time. But our study provides statistical evidence for a common cycle, suggesting that these geologic events are correlated and not random."
The new study is not the first time that there's been a suggestion of a planetary geologic cycle, but it's only with recent refinements in radioisotopic dating techniques that there's evidence supporting the theory. The authors of the study collected the latest, best dating for 89 known geologic events over the last 260 million years:
- 29 sea level fluctuations
- 12 marine extinctions
- 9 land-based extinctions
- 10 periods of low ocean oxygenation
- 13 gigantic flood basalt volcanic eruptions
- 8 changes in the rate of seafloor spread
- 8 times there were global pulsations in interplate magmatism
The dates provided the scientists a new timetable of Earth's geologic history.

Putting all the events together, the scientists performed a series of statistical analyses that revealed that events tend to cluster around 10 different dates, with peak activity occurring every 27.5 million years. Between the ten busy periods, the number of events dropped sharply, approaching zero.
Perhaps the most fascinating question that remains unanswered for now is exactly why this is happening. The authors of the study suggest two possibilities:
"The correlations and cyclicity seen in the geologic episodes may be entirely a function of global internal Earth dynamics affecting global tectonics and climate, but similar cycles in the Earth's orbit in the Solar System and in the Galaxy might be pacing these events. Whatever the origins of these cyclical episodes, their occurrences support the case for a largely periodic, coordinated, and intermittently catastrophic geologic record, which is quite different from the views held by most geologists."
Assuming the researchers' calculations are at least roughly correct — the authors note that different statistical formulas may result in further refinement of their conclusions — there's no need to worry that we're about to be thumped by another planetary heartbeat. The last occurred some seven million years ago, meaning the next won't happen for about another 20 million years.
Considering how much sharks are feared by humans, it is a bit of a surprise that scientists don't know much about the predators. For example, until recently, sharks were thought to be solitary creatures searching the seas for food on their own. Now it appears that some sharks are quite social.
Another mystery is how these prehistoric swimming and eating machines digest food. Although scientists have made 2D sketches of captured sharks' digestive systems based on dissections, there is a limit to what can be learned in this way. Professor Adam Summers at University of Washington's Friday Harbor Labs says:
"Intestines are so complex, with so many overlapping layers, that dissection destroys the context and connectivity of the tissue. It would be like trying to understand what was reported in a newspaper by taking scissors to a rolled-up copy. The story just won't hang together."
Summers is co-author of a new study that has produced the first 3D scans of a shark's intestines, which turns out to have a strange, corkscrew structure. What's even more bizarre is that it resembles the amazing one-way valve designed by inventor Nikola Tesla in 1920. The research is published in the journal Proceedings of the Royal Society B.
What a 3D model reveals

According to the study's lead author Samantha Leigh, "It's high time that some modern technology was used to look at these really amazing spiral intestines of sharks. We developed a new method to digitally scan these tissues and now can look at the soft tissues in such great detail without having to slice into them."
"CT scanning is one of the only ways to understand the shape of shark intestines in three dimensions," adds Summers. The researchers scanned the intestines of nearly three dozen different shark species.
It is believed that sharks go for extended periods — days or even weeks — between big meals. The scans reveal that food passes slowly through the intestine, affording sharks' digestive system the time to fully extract its nutrient value. The researchers hypothesize that such a slow digestive process may also require less energy.
It could be that this slow digestion is more susceptible to back flow given that the momentum of digested food through the tract must be minimal. Perhaps that is why sharks evolved something so similar to a Tesla valve.

Tesla's "valvular conduit," or what the world now calls a "Tesla valve," is a one-way valve with no moving parts. Its brilliance is based in fluid dynamics and only now coming to be fully appreciated. Essentially, a series of teardrop-shaped loops arranged along the length of the valve allow water to flow easily in one direction but not in the other. Modern tests reveal that at low flow rates, water can travel through the valve either way, but at high flow rates, the design kicks in. According to mathematician Leif Ristroph:
"Crucially, this turn-on comes with the generation of turbulent flows in the reverse direction, which 'plug' the pipe with vortices and disrupting currents. Moreover, the turbulence appears at far lower flow rates than have ever previously been observed for pipes of more standard shapes — up to 20 times lower speed than conventional turbulence in a cylindrical pipe or tube. This shows the power it has to control flows, which could be used in many applications."
A deeper dive
Summers suggests the scans are just the beginning. "The vast majority of shark species, and the majority of their physiology, are completely unknown," says Summers, adding that "every single natural history observation, internal visualization, and anatomical investigation shows us things we could not have guessed at."
To this end, the researchers plan to use 3D printing to produce models through which they can observe the behavior of different substances passing through them — after all, sharks typically eat fish, invertebrates, mammals, and seagrass. They also plan to explore with engineers ways in which the shark intestine design could be used industrially, perhaps for the treatment of wastewater or for filtering microplastics.
It could fairly be said, though, that Nikola Tesla was 100 years ahead of them.
