„Cellular automata are now being used to model varied physical phenomena normally modelled by wave equations, fluid dynamics, Ising models, etc. We hypothesize that there will be found a single cellular automaton rule that models all of microscopic physics; and models it exactly. We call this field DM, for digital mechanics.“

„There are models of development that already exist in developing countries that actually are much more sustainable than the model of free markets that we have been trying to export.“

Contexto: We are all familiar with the idea: Give a man a fish and you'll feed him for a day, but teach a man to fish and you'll feed him for a lifetime. That sounds reasonable enough. … But think of the model that rests on. It constructs people in developing countries that sort of people sitting by the rivers and eating fish and then they look at the river and said: "- So what's that? - It looks like a fish. - Well, how do we get it out? - Well I have no idea, we would have to wait for white man to come and tell us." It's important to remember that actually there are systems of governance that already exist. There are models of development that already exist in developing countries that actually are much more sustainable than the model of free markets that we have been trying to export.
