Circular economies and modern cities - Great description of circular economies in the context of building modern cities, with great examples, the guy knows his stuff. This type of circularity can be very good for society. I feel though it misses some of the nuance and dark realities of inner city living that makes some of the optimisations mentioned practically difficult to implement in a way that everyone finds safe. The second half of this interview gets a bit hard to watch though. Some people, whatever it is they have been through in their lives, has led them down a path of being deeply manipulative. I watch this and wonder how badly damaged we all are. #
