What Is a Simulation?

What if, in our post modern society, practically everything about the way that people see their lives is seen through the lens of a complex network of signs and symbols given to them by media? What if we similarly live every day in a world that we accept to be reality that prevents us from seeing the world as it actually is? What if our simulation isn't housed in computer hardware? What if it's all around us? i get that this is a lot and its going to take some clarifications and examples. But remember, what we're also talking about in this episode are some of the theories from the early eighties of what a society's going to look like post post-modernism
