All right, good morning everybody. Yeah, so I've been wanting to cover this topic for a little bit, but it is, it's kind of a byzantine topic, so I'm going to try and make it as interesting as possible. But the long story short is that what is emerging is that the correct way to think about artificial intelligence, safety and regulation is through the lens of complex adaptive systems or cas. Or cas. So complex adaptive systems are. Well, let me just give you two kind of examples off the top. So the one that you're probably most familiar with is going to be the stock market. And I'll give you an explanation as to how the stock market is characterized as a complex adaptive system in just a second. But the other one is social media. So in both cases you can see viral effects, you also see emergent behaviors, and so on and so forth. So with those two in mind, the stock market and social media, let me give you the top, I think nine or ten criteria of complex adaptive systems. And this will give you a little bit more context as to what do we mean, what are the characteristics of these complex adaptive systems? So number one is emergence. Emergence is the appearance of complex or higher order behaviors or patterns of behavior that emanate or originate from simpler lower level rules. And so an example of emergence is flocking behavior. So, so birds and schools of fish, they actually follow very simple rules, but because they're following simple rules in large numbers as individual agents, they can actually respond to each other in dynamic ways as well as predators. So for instance, if you've ever watched a video where like a shark swims through a school of fish, and the school of fish just parts like the Red Sea, that is an emergent behavior. Next is self organization. So self organization is the spontaneous creation of order and structure within the system, however, without external control or direction. So that self organization, for instance, the way that ants tend to organize their colonies and their, and the way that bees organize their hives, that is another example of self organization. Although I don't know whether or not like schools of fish or beehives, I don't know if this qualifies complex adaptive systems, but they do actually embody some of these characteristics. Next is non linearity. So relationships between components that are not proportional, leading to unpredictable outcomes, making the system difficult to model using simple linear equations. So non linearity is basically the equivalent of stuff being viral. So viral media is an example of non linearity. But then also you can look at, at examples in the stock market, like the flash crash that happened, gosh, probably 10 years ago now, where basically, you know, one per one, one trader accidentally put a billion instead of a million and was selling too many orders and it caused huge ripple effects. Not only did the price of one stock crash, but everyone started panicking. And so you have, you have these contagion effects where, you know, one unexpected behavior results in more unexpected behavior behavior in other nodes in this complex adaptive system. Another is feedback loops. So feedback loops have two primary orientations. So one is positive feedback loops or virtuous cycles, and negative feedback loops or vicious cycles. So in the case of a positive feedback loop, this is where energy begets more energy. Or in other cases for negative feedback loops, this is where every successive iteration is worse or has diminishing returns. So an example of a positive feedback loop that you're probably familiar with is compounding interest or compounding returns. So for instance, if you earn 10% per year between, you know, capital gains and interest or whatever, then that interest compounds because the gains that you get one year feed into the next year. Whereas a negative feedback loop would be something like diminishing returns. So like the marginal gains on some kinds of investments don't actually improve. So like say for instance, this year an investment gives you yields 10%, but next year it only yields 9% due to margins or lack of scalability or that sort of thing. So that's feedback loops. That's number four Number five is adaptation. So adaptation is seen in complex adaptive systems, which is that the system as a whole modifies its behavior in response to the changing environment. Another way to think about this is the infinite game. So in an infinite game, the purpose of the game is to keep playing. And by virtue of the fact that every system has attractor states or terminal conditions, in order for the game to keep playing, the rules need to change. And so this is adaptation, which is basically the stock market keeps going forever. So what happens, the rules around the stock market change, regulations change, the SEC changes and that sort of thing, but then also investor behavior changes, company behavior changes. And so when you have marketplaces, in particular stock markets, where you have many stakeholders, you have retail investors, you have commercial investors, you have government regulators, and then you have the companies whose stocks are being traded in the first place. So you have many, many different categories of agents, all of whom can adapt their behavior. And by adapting their behavior according to what the system is doing, this is one of the key, key, like central criteria of a complex adaptive system is that the, the beliefs about how the system works or the observations of the system can modify all the behaviors of all the players in that system, which is why you can get those viral effects. Next is co evolution. So in the context of the stock market, again you have those different kinds of stakeholders that are all reacting to each other so that not only does the system itself evolve over time, so for instance in the stock market, the brokerages that are participating, the exchanges that are participating, the companies you know are listed and delisted and that sort of thing. And then also over time investor sentiment becomes more nuanced, more sophisticated. But then you also get like an example of adaptation or co evolution is the memeification. The emergence of meme stocks is an example of complex adaptive systems in real time. So I'm referring to GameStop as a primary example where an entire like aberrant, like just set of beliefs and behaviors was created in one set of nodes with which then started manipulating the stock price. And that was in reaction to other people manipulating the stock price through naked short selling. So that is an example of co evolution. Let's see, we'll skip diversity because we're already talking about that. The last two are I think the most interesting to me. So number eight is edge of chaos. So edge of chaos is the balance point between order and disorder, where complex systems tend to be the most adaptable and creative. So in a case of a system that is too noisy or too chaotic, nothing can really happen. And so then entropy just takes over. If entropy takes over, then you have just noise. Nothing productive happens. However, if you have too much order or too much structure, if it's too rigid, then you don't get enough variation. So you need to balance the amount of entropy in a system. And so the edge of chaos is kind of that optimal trade off between order and disorder. And this is going to be really important when we talk about technology in general and artificial intelligence in particular. And then the final one is attractor states. So an attractor state is a condition or pattern towards which a system tends to evolve regardless of the starting point. So attractor states are created largely, not entirely, but largely by incentives. So the incentive structures or the reward mechanisms that exist within the system in order to guide behavior. So for instance, in ants and bees, one of the reward signals, one of the incentives is food, right? And so behavior of ants is largely driven by where they find food. And so you know, the lines that they find that they form where the colonies tend to be established.
