All this is one of the reasons that I see the city as pointing the way to the future. We know we need to learn to do without greed, if we’re going to survive on a planet with limited resources, but perhaps we need to learn to do without ambition, too. I know it sounds boring, not to mention unrealistic, but when I look around at what the human ego has wrought of late, I’m not sure how much more ambition we can live with.
