The Complexity of a System

A phone is not a complex system because it does what it's supposed to do. When you take nature as an example, I'm going to use birds. That is a system built up of parts being the birds or the organisms. But they are autonomous because each bird is its own thing. So that energy keeps the system together. In a dynamic environment, i.e. the world in this example, yeah, it takes energy to keep those systems together. And when the energy isn't enough or the energy isn’t maintained, entropy happens. The birds fly away. The ants go off in different directions. You've added lots of jargon is straight away. To pick it apart
