The first question is not economic but political: what is a city for?
If the rulers pursue merely wealth, efficiency, and technical power, the polis loses its soul. Yet if citizens reject every transformation out of fear, they condemn themselves to stagnation.
The danger is that neither side truly understands the Good. The engineers speak in numbers; the citizens speak in anxieties. Neither speaks philosophically.
Modern cities no longer possess philosopher-statesmen capable of explaining technological destiny in moral terms.
