I think there's a lot of gold to be mined in the seams between disciplines.
For instance, I would not have thought of a city as a social system. It is clear that a city is a very different beast to a corporation though both are types of social systems. What other types of social systems are there? And how do they behave? Do they all exhibit such stark universality when you look at them as space-filling fractal networks of social communication?
What about the military? Does it behave like a city or a corporation? What about the civil service? What about universities? And so on, and so on.
What about the internet? Is that one giant social system? If so, what type? Or does it just count as infrastructure?
Even though the video was fascinating and thought provoking I feel I have many more questions now than I did beforehand.

I think you're absolutely correct.
Absolutely, Cybernetics and Systems Theory for instance are founded exactly on that premise. You might enjoy http://www.art-sciencefactory.com/complexity-map_feb09.html
