Question: What am I talking about?
"Each unit is connected to many other units. The signals are either positive in value or negative in value. Each unit adds up the total influence of signals that it receives and then sends along its outward connection a signal whose value is a function of that sum. That's about all there is to it. The elements are all simple; the complexity and power come from the fact that there are a large number of interconnected units trying to influence the activities of others. All this interconnection leads to massive interaction among the units, with the signals sometimes leading to fights and conflicts, sometimes to cooperation and stability. After a while, however, the system of interconnected units will eventually settle down to a stable state that represents a compromise among the opposing forces."
