Why Cities Grow, Corporations Die, and Life Gets Faster

Summary: As organisms, cities, and companies scale up, they all gain in efficiency, but then they vary. The bigger an organism, the slower. Yet the bigger a city is, the faster it runs. And cities are structurally immortal, while corporations are structurally doomed. Scaling up always creates new problems; cities can innovate faster than the problems indefinitely, while corporations cannot.

IMHO: Its a long video but has some great information about how cities and corporation grow and die.
