Aerodynamics For Cognition

Tom Griffiths [8.21.17]

It's very clear that in order to make progress in understanding some of the most challenging and important things about intelligence, studying the best example we have of an intelligent system is a way to do that. Often, people who argue against that make the analogy that if we were trying to understand how to build jet airplanes, then starting with birds is not necessarily a good way to do that.                                 

That analogy is pretty telling. The thing that's critical to both making jet airplanes work and making birds fly is the structure of the underlying problem that they're solving. That problem is keeping an object airborne, and the structure of that problem is constrained by aerodynamics. By studying how birds fly and the structure of their wings, you can learn something important about aerodynamics. And what you learn about aerodynamics is equally relevant to then being able to make jet engines.                                 

The kind of work that I do is focused on trying to identify the equivalent of aerodynamics for cognition. What are the real abstract mathematical principles that constrain intelligence? What can we learn about those principles by studying human beings?

Benevolent Artificial Anti-Natalism (BAAN)

Thomas Metzinger [8.7.17]

Obviously, it is an ethical superintelligence not only in terms of mere processing speed, but it begins to arrive at qualitatively new results of what altruism really means. This becomes possible because it operates on a much larger psychological data-base than any single human brain or any scientific community can. Through an analysis of our behaviour and its empirical boundary conditions, it reveals implicit hierarchical relations between our moral values of which we are subjectively unaware, because they are not explicitly represented in our phenomenal self-model. Being the best analytical philosopher that has ever existed, it concludes that, given its current environment, it ought not to act as a maximizer of positive states and happiness, but that it should instead become an efficient minimizer of consciously experienced preference frustration, of pain, unpleasant feelings and suffering. Conceptually, it knows that no entity can suffer from its own non-existence.

The superintelligence concludes that non-existence is in the own best interest of all future self-conscious beings on this planet. Empirically, it knows that naturally evolved biological creatures are unable to realize this fact because of their firmly anchored existence bias. The superintelligence decides to act benevolently.

Learning By Thinking

Tania Lombrozo [7.28.17]

Sometimes you think you understand something, and when you try to explain it to somebody else, you realize that maybe you gained some new insight that you didn't have before. Maybe you realize you didn't understand it as well as you thought you did. What I think is interesting about this process is that it’s a process of learning by thinking. When you're explaining to yourself or to somebody else without them providing feedback, insofar as you gain new insight or understanding, it isn't driven by that new information that they've provided. In some way, you've rearranged what was already in your head in order to get new insight.

The process of trying to explain to yourself is a lot like a thought experiment in science. For the most part, the way that science progresses is by going out, conducting experiments, getting new empirical data, and so on. But occasionally in the history of science, there've been these important episodes—Galileo, Einstein, and so on—where somebody will get some genuinely new insight from engaging in a thought experiment.

Things to Hang on Your Mental Mug Tree

Rory Sutherland [7.10.17]

I don't think there's any huge amount of intelligence required to look at the world through different lenses. The difficulty lies in that you have to abandon four or five assumptions about the world simultaneously. That's what probably makes it difficult.

Where Avant-Garde Thinking Reflects The Present

Tobias Sedlmaier [6.30.17]

20 years: Online platform
Where Avant-Garde Thinking Reflects The Present
By Tobias Sedlmaier 6.30.2017

The online platform Edge has been looking for the big questions for twenty years - and for the even bigger answers of life. A critical appraisal.

Internet Presence of Edge (photo: screenshot)

In the beginning is the question. Born out of restless nights and ingenious inspirations, it is examined in cold daylight, perhaps focused more precisely, and sent out by its ingenious creators into the ignorant world.

What sounds like a diffusely romantic myth of origin is in fact the recurrent practice of finding Edge’s Annual Question. On this online platform, major contemporary (mostly American) scientists and a selection of trendsetters have been formulating answers to more or less urgent questions of our time for twenty years.

How does the world work?

These can be very vague, for example: What Now? Or they can be leading questions: What Scientific Idea Is Ready for Retirement? Almost always the notion of big ideas—either brilliant or dangerous ones—resonates here; and of course, life, the internet, and all the other themes come in.

The answers, which are first published on the website, later in book form, can be long essays with examples and formulas that run five print pages. Or they are as aphoristic as Brian Eno's response about the value of the Internet:  "The great promise of the Internet was that more information would automatically yield better decisions. The great disappointment is that more information actually yields more possibilities to confirm what you already believed anyway.“

Master of Ceremonies of this sophisticated debate forum is John Brockman, author and literary agent, who is called a giant by some. The industrious intellectual impresario has himself written a handful of books, edited around fifty more and performed in an inter-disciplinary  program of avant-garde events with John Cage and Jorge Luis Borges in New York. He was also a Godfather for the think tanks "Reality Club" as well as Edge.

At a moment in history when borders are erected more quickly than torn down, you can imagine the larger than life Brockman with his characteristic wide-brimmed hat as an iconoclastic breaker of barriers. He is equally at home in the role of the business-minded entrepreneur as in the role of the theorist well aware of the sensitive changes in the Zeitgeist, oscillating between Andy Warhol and Norbert Wiener, at the intersection of art and cybernetics.

Compassionate Systems

Daniel Goleman [6.22.17]
One way a systems perspective could help with the environmental crisis is through understanding that we have a very narrow range of affordances, the choices presented to us. For example, I have this jacket, you have this table or the chair I’m sitting on, and they are manufactured with industrial platforms that have more or less been the same for a century. Yet in the last ten or fifteen years, we’ve seen the emergence of industrial ecology, a science that offers a metric for understanding the impacts of the life cycle of any of these objects from beginning to end in terms of how they impact the global systems that support life on our planet—the carbon cycle being the best-known. Now that we have that data and a metric for it, we can better manage the processes that are entailed in the use and manufacture of every object we own. We have a metric for reinventing everything in the material world to be supportive of those life-support systems.

Curtains For Us All?

Martin Rees [5.31.17]
Here on Earth, I suspect that we are going to want to regulate the application of genetic modification and cyborg techniques on grounds of ethics and prudence. This links with another topic I want to come to later about the risks of new technology. If we imagine these people living as pioneers on Mars, they are out of range of any terrestrial regulation. Moreover, they've got a far higher incentive to modify themselves or their descendants to adapt to this very alien and hostile environment.                                 
They will use all the techniques of genetic modification, cyborg techniques, maybe even linking or downloading themselves into machines, which, fifty years from now, will be far more powerful than they are today. The posthuman era is probably not going to start here on Earth; it will be spearheaded by these communities on Mars.

The Threat

Ross Anderson [5.8.17]
People who are able to live digitally enhanced lives, in the sense that they can use all the available tools to the fullest extent, are very much more productive and capable and powerful than those who are still stuck in meatspace. It’s as if you had a forest where all the animals could see only in black and white and, suddenly, along comes a mutation in one of the predators allowing it to see in color. All of a sudden it gets to eat all the other animals, at least those who can’t see in color, and the other animals have no idea what’s going on. They have no idea why their camouflage doesn’t work anymore. They have no idea where the new threat is coming from. That’s the kind of change that happens once people get access to really powerful online services.
So long as it was the case that everybody who could be bothered to learn had access to AltaVista, or Google, or Facebook, or whatever, then that was okay. The problem we’re facing now is that more and more capable systems are no longer open to all. They’re open to the government, to big business, and to powerful advertising networks.

Soul of a Molecular Machine

Venki Ramakrishnan [5.1.17]

We're now accumulating data at an incredible rate. I mentioned electron microscopy to study the ribosome—each experiment generates several terabytes of data, which is then massaged, analyzed, and reduced, and finally you get a structure. At least in this data analysis, we believe we know what's happening. We know what the programs are doing, we know what the algorithms are, we know how they come up with the result, and so we feel that intellectually we understand the result. What is now happening in a lot of fields is that you have machine learning, where computers are essentially taught to recognize patterns with deep neural networks. They're formulating rules based on patterns. There are are statistical algorithms that allow them to give weights to various things, and eventually they come up with conclusions.

When they come up with these conclusions, we have no idea how; we just know the general process. If there's a relationship, we don't understand that relationship in the same way that we would if we came up with it ourselves or came up with it based on an intellectual algorithm. So we're in a situation where we're asking, how do we understand results that come from this analysis? This is going to happen more and more as datasets get bigger, as we have genome-wide studies, population studies, and all sorts of things.

We're at the threshold of a new age of structural biology, where these things that everybody thought were too difficult and would take decades and decades, are all cracking. Now we're coming to pieces of the cell. The real advance is that you're going to be able to look at all these machines and large molecular complexes inside the cell. It will tell you detailed molecular organization of the cell. That's going to be a big leap, to go from molecules to cells and how cells work.

In almost every disease, there's a fundamental process that's causing the disease, either a breakdown of a process, or a hijacking of a process, or a deregulation of a process. Understanding these processes in the cell in molecular terms will give us all kinds of ways to treat disease. They'll give us new targets for drugs. They'll give us genetic understanding. The impact on medicine is going to be quite profound over the long-term.

Urban Evolution

How Species Adapt, or Don't, to City Living Jonathan B. Losos [3.31.17]
We realize evolution can occur very rapidly. Yet, despite this realization, very few people have taken the next logical step to consider what's happening around us, where we live. Think about the animals that live just around you. Look out your window in your backyard. . . . All the animals living around us are facing new environments, coping with new food, new structures, new places to hide, and in many cases new temperatures. These are radically different environments. If, as we now believe, natural selection causes populations to adapt to new conditions, why shouldn't it be happening to those species living around us in the very new conditions?
