Growing ever more sophisticated and realistic social models, we also have to say that well, if we have only sugar, there might be more than one resource. Actually, and there is usually more than one resource or one good or service that we are after, additionally to be a social or cultural pressures that might be upon us, environmental pressures. So let's see what happens if we introduce a second resource. So spice. We now get sugar and spice, and we turn that on, and we see that sugar is where it is on the bottom left and on the top right, then the other two sides on the top left on the bottom right, there's now spice, our second resource. Here, we have our setup with two resources. Here, we have our sugar, and now we add here our spice to it additionally, and agents have to click both of it. So they have a diversity, agent-based modeling. We reprogram our diversity among agents, but they have to at least to some degree, collect both of it. We can see if we have our first two steps, we already have some specialization. These blue ones are the ones who require more spices, and the red ones are the ones who require more sugar, and the black ones are going to require a mix of both of it. So obviously, for the blue one, it makes sense to stay here, and for the red ones, it makes sense to specialize over there. As we run our simulation, one first thing that we can notice as we accelerate a little bit, is that wow, the agent count is going down tremendously. It's a really hard life to collect both these species. We're down at 120 agents, that's really little. They say for us men, it's really hard to multitask. So I can feel them. Imagine you have to concentrate on two things at the same time, that's a really hard life. You can see that is the effect and it still continues to go down, and still continues to go down the number of agents. Now, we can also follow some individual agents here, we inspect them, and we watch them. We can see that it accelerating a little bit. Yeah. Right now, this agent is filling up on spice, but eventually, if the agent wants to survive, it cannot only hang out in spice, it also has to collect some sugar, and then running out of sugar, we're going back to spice, depending on the metabolism the agent still has to multitask. That is really hard. If you specialize only on one, the one thing you are lucky enough that it's enough for you to concentrate on one thing, it's easy and you have higher chances of survival in the simulation. Otherwise, you have to have a pretty good vision probably to be tested. You can look at that in order to be able to move around and satisfy all of your different needs. One response that societies collectively develop as a response to these multiple demands that we are having, is a trade system. So basically, we can still specialize on something. S. Ricardo, one of the founding fathers of economics, then showed, it's better to specialize on one thing and then later to trade, and that can optimize the system as a whole, and that's what we've also been doing. So we can set up a trade system here. We now said go, we can first of all, see that here, the trade will starts out, a lot of nest agents will use it as it gets reduced, and here we need a price. A price in a system, in an economic system, and an economic price is basically in emergent phenomena that reflects the supply and the demand of something. So if these dots are below the red line, that means that spice is higher value than sugar, and if it would be above the red line, it would mean that sugar is higher value than spice. Finding this equilibrium is called [inaudible] laws of Russian process of finding the price, finding a stable price which mediates between supply and demand of these different products. That's what you can basically create here. You can also see since the price is basically an emergent phenomena coming out of supply and demand, we can change it and see how sensitive it is. For example, we could increase the sugar grow back interval, and increase it to let's say four intervals. So sugar is growing slower now, growing only a quarter of this piece, and we can see well, sugar is now more highly valued, because sugar is more in demand, there's less often, it's more scarce, so the value of it goes up. There are more people who now suddenly want sugar. On the other hand, if you know, the other way round and increase the scarcity of spices. We can see, we basically destroy the price, it goes down. Here, the price of sugar and now spice is the scarce resource. The price at the end, evolves according to the law of scarcity, balancing between supply and demand. That is not different from the price of Bitcoin, the price of gold, or the price of spices and sugar. As you can see here, if supply and demand is in equilibrium, it goes back again. One thing you can notice here, is that we don't have these red and blue specialists anymore. Even the average agent can survive, which is great because we're not all specialists, and in most of us are actually more average, and the trading system helps us to survive because we can help each other out. So as a society, we can make up for it.
