How algorithms shape our world - Kevin Slavin

[@TEDEd]

We're adding some TEDTalks on the weekends that students/teachers have identified as useful. Each Talk comes with a new and customizable Lesson on the TED-Ed website. Just follow the link in the description or the annotation at 00:10 to view the lesson. We'll still be posting at least 4 new educator + animator Lessons every week. Enjoy!

7 years old and still so relevant, amazing talk

[@Mimas2115]

Mos of the time, when I ask people who work in IT/CS what an 'algorithm' is, they always respond with some jargon and jumble a lot of words together that barley formes a cohesive sentence, but this was beautifully and clearly explained. Thank you Kevin!

[@ClassyNova]

This by far the easiest explanation of Algorithms and their process in the world, that I have heard to date, and I have heard many. TED-ED and TED-Talks are very addictive to those who love to grasp something new and exciting,, to expand their minds...and to learn.

[@Utspeladfz]

I don't quite understand it either. But what the general idea is that we have an market based on algorithms which are communicating with themselves unsupervised by humans. Which can either create total chaos if we don't learn to understand it, or the other way, if we actually learn to understand it.

[@HowardBregman]

I thought this talk effectively linked 3 realms that may seem independent, but are not. Algorithms link the theoretical world (the science of BIG DATA) to the physical world (building design-architecture, geography) to the financial world (High speed trading). Fascinating? Absolutely! Useful? Maybe, still workin' on it!

[@serenitystocks3917]

"I always find it extraordinary that so many studies are made of price and volume behavior, the stuff of chartists. Can you imagine buying an entire business simply because the price of the business had been marked up substantially last week and the week before? Of course, the reason a lot of studies are made of these price and volume variables is that now, in the age of computers, there are almost endless data available about them. It isn’t necessarily because such studies have any utility; it’s simply that the data are there and academicians have worked hard to learn the mathematical skills needed to manipulate them. Once these skills are acquired, it seems sinful not to use them, even if the usage has no utility or negative utility. As a friend said, to a man with a hammer, everything looks like a nail."

[@TrentFillmore1]

Slavin's point is well taken: a red STOP button is not enough control over a system to make it accountable to us. After watching Slavin's presentation, I am highly motivated to find a solution. Where no solution presents itself within our core assumptions, our core assumptions should be challenged. In this case, finding a solution requires us to visit deeper abstractions, ones so ingrained in our culture, we don't even see them as cultural. Slavin questions the unmonitored power we give to computers to automatically get us money, but not the idea of getting money without any work itself being a form of usury infinitely worse than profiteering from money-changing or charging interest. At least money-changers are doing some work. At least some people see what they are doing as beneficial. The usury Slavin is talking about is disgustingly sicker: taking wealth from society without returning any benefit at all, and without any work, time or thought. Completely lost in Slavin's equation is the idea that money is a type of economic system, and that economic systems are supposed to make things more economical: 1) to systemically provide the most benefit for the least amount of work, and 2) to enable their constituents to promote the kind of community they want with their skills and labor. Money has no big red STOP button because we have allowed our world's money changers to kill economic systems that are honest, ones that account for real wealth and benefit rather than fraudulently try to store it. Pecuniary economics has become so ingrained, we attempt to find solutions WITHIN an assumption of money, missing the point completely that money itself is a scam, an artificial store of value. No computer system designed to help steal wealth from society via money's deceitful claim to be valuable is going to produce anything beneficial because the foundation it builds everything upon is corrupt, compensating most those who steal rather than produce. The machine controlling us goes back millennia, not just a few hundred years in the stock market. Our supposedly superior intelligence has created a dead end for humanity completely at odds with: the economies of all past evolutionary epochs, our ability to transcend any pending singularity, and growth through any future technological abstraction. Slavin is right that we are creating monsters HUMANS cannot control, but our computerized monsters DO serve a master, and that master is pecuniary economics, an entrenched scam created near the dawn of recorded history with one purpose in mind: to steal from people who create stuff, to benefit those who do not. THAT is the monster to which we gave birth, and no longer control. While it lives in a monopoly, trying to make its servants accountable to us in any form more complex than STOP is futile.

[@Sirajkabeer080]

Well said.

[@ms9771]

So you have to fight USARY law of Talmud by Jewish law, Wall street , obey Jewish law, USURY , Talmud encourage lending money with interest to none Jews,. But the halakha (Jewish law) that prescribes interest-free loans applies only to loans made to other Jews. so wall street run by Jewish law allows making loans with interest to persons who are not Jewish. now you can see why most rich are Jewish,also hate none Jews have Union to help each other, when those Jews have union, and help each other

[@Jack_X075]

Focus on what he says at 8:49, mind blown......

[@himarit1484]

now architecture is indispensable with algorism. Either we reconstruct idea on the digital world, or just let the algorithms to generate the unpredictable shape. That is what I am as the first-year student in architecture tackling into.

[@Utspeladfz]

What I don't understand is why and how they have freed themselves from the human grip and are now working on a unsupervised level. I find this extraordinary, and if it's true what he's saying, that mathematics are working on a level comparable to nature, which we can learn to understand - we have the opportunity to create a nature of our own, through math! And this will revolutionize the very belief that economy is only an idea. I would like to read more of this to understand better!

This guy just blew my mind

[@elapplzsl]

So wait why don't we understand an algorithm that we create or are these algorithms are "free" from human influence?(I'm referring to knife, carnival ect algorithms)

[@bens5859]

Those "algorithms" exhibit patterns just like man-made algorithms do, but they are not man made. They are the result of different man-made algorithms interacting with one another. When some already-complex algorithms interact with one another, the complexity of the combined algorithms increases dramatically, which is why we don't yet understand them.

[@elapplzsl]

Ben Stegeman Ah thanks so the speaker is referring to the combined understanding of the algorithmic system not a particular single one. I got confused thinking it was these single algorithms that we can't understand.

[@bens5859]

elapplzsl Well, the combined algorithms do act as single algorithms, but we don't understand them because we aren't exactly sure how the ingredient algorithms are interacting with one another to create the result algorithm. But yes, it would certainly be bad news if we didn't understand the algorithms that we make ourselves. (Although I suspect that when multiple people collaborate on an algorithm, this can be the case.)

[@Arkhanno]

While it is an alt account he is right. The 'soul' is just a way for humans to describe something we can't fully understand or properly define.

[@armandocastro6914]

There's always a tendency to sell complex systems (math, chemistry, physics, biology, etc.) by using mystical images. Having done that, we are tempted to call the result and "explanation." Mystification, however, is not explanation.

This is a lot of energy and time being spent denying one simple fact: Everyone has everything. If you increase speed to the point where simultaneity happens, that is what you get. So, the effort is to keep chasing simultaneity, but what happens if you catch it? Honestly, economics has already passed the point of diminishing returns. But we keep trying to bleed it for more gain. Sad.
