Urban centers support people more efficiently than do small towns, villages, and the countryside. This isn't just true environmentally or economically; it's arguably also the case when it comes to the kind of intellectual ferment that drives innovation. New ideas are the sparks coming from the friction between minds -- and you get a lot more friction in the city. Urban growth, over time, makes us all stronger.

Cities require complex support systems, however. Complex infrastructure offers plenty of opportunities for failure, whether via natural disasters or human causation. Isolated failures will happen, and not pose a systemic threat. But repeated -- or un-repaired -- system failures would inevitably drive people out of the cities, by choice or by necessity.
