Compassionate Systems

[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?

[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, which is 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 post-human era is probably not going to start here on Earth; it will be spearheaded by these communities on Mars. That's the vision I would have of Mars. It's people out there who will perhaps lead to these developments, which will then eventually lead to posthumans, maybe electronic rather than organic, spreading far beyond our solar system. If that's happened elsewhere, that's the sort of thing we might detect.

The Threat

[5.8.17]

Although a security failure may be due to someone using the wrong type of access control mechanism or weak cypher, the underlying reason for that is very often one of incentives. Fundamentally, the problem is that when Alice guards a system and Bob pays the cost of failure, things break. Put in those terms, it’s simple and straightforward, but it’s often much more complicated when we start looking at how things actually fail in real life.

Soul of a Molecular Machine

[5.1.17]

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
[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?

Closing the Loop

[3.7.17]

Closing the loop is a phrase used in robotics. Open-loop systems are when you take an action and you can't measure the results—there's no feedback. Closed-loop systems are when you take an action, you measure the results, and you change your action accordingly. Systems with closed loops have feedback loops, they self-adjust and quickly stabilize in optimal conditions. Systems with open loops overshoot; they miss it entirely.

The Function of Reason

[2.22.17]

Contrary to the standard view of reason as a capacity that enhances the individual in his or her cognitive capacities—the standard image is of Rodin’s "Thinker," thinking on his own and discovering new ideas—what we say now is that the basic functions of reason are social. They have to do with the fact that we interact with each other’s bodies and with each other’s minds. And to interact with other’s minds is to be able to represent a representation that others have, and to have them represent our representations, and also to act on the representation of others and, in some cases, let others act on our own representations.

The kind of achievements that are often cited as the proof that reason is so superior, like scientific achievements, are not achievements of individual minds, not achievements of individual reason, they are collective achievements—typically a product of social interaction over generations. They are social, cultural products, where many minds had to interact in complex ways and progressively explore a lot of directions on which they hit not because some were more reasonable than others, but because some were luckier than others in what they hit. And then they used their reason to defend what they hit by luck. Reason is a remarkable cognitive capacity, as are so many cognitive capacities in human and animals, but it’s not a superpower.

Defining Intelligence

[2.7.17]

I worked on coming up with a method of defining intelligence that would necessarily have a solution, as opposed to being necessarily unsolvable. That was this idea of bounded optimality, which, roughly speaking, says that you have a machine and the machine is finite—it has finite speed and finite memory. That means that there is only a finite set of programs that can run on that machine, and out of that finite set one or some small equivalent class of programs does better than all the others; that’s the program that we should aim for.                                 

That’s what we call the bounded optimal program for that machine and also for some class of environments that you’re intending to work in. We can make progress there because we can start with very restricted types of machines and restricted kinds of environments and solve the problem. We can say, "Here is, for that machine and this environment, the best possible program that takes into account the fact that the machine doesn’t run infinitely fast. It can only do a certain amount of computation before the world changes."

The Mind Bleeds Into the World

[1.24.17]

Coming very soon is going to be augmented reality technology, where you see the physical world, but also virtual objects and entities that you perceive in the middle of them. We’ll put on augmented reality glasses and we’ll have augmented entities out there. My face recognition is not so great, but my augmented glasses will tell me, "Ah, that’s John Brockman." A bit of AI inside my augmented reality glasses will recognize people for me.                 

At that level, artificial intelligence will start to become an extension of my mind. I suspect before long we’re all going to become very reliant on this. I’m already very reliant on my smartphone and my computers. These things are going to become more and more ubiquitous parts of our lives. The mind starts bleeding into the world. So many parts of the world are becoming parts of our mind, and eventually we start moving towards this increasingly digital reality. And this raises the question I started with: How real is all of this?
