Virgil Ierubino asks if you could build a city from the ground up, how would you do it? I don't just mean the buildings. By 'city' I mean the collection of humans and facilities and services and systems that collectively form a functioning society. Would you make different decisions than those which are made for us, all around us, every day? Or, realising that this question assumes you are in a position of considerable power, maybe you'd just go nuts?
