Pangloss, I think, mentioned Jane Jacobs she maintained that citys are not designed for people they are designed mainly for commerce and vehicle traffic, and they are. Our large urban areas are dirty, fast, noisey and they don't get dark. They are very expensive in that everything consumed in them must be imported and they are power holes, they bleed energy. Big citys are probably soon to be things of the past. Water and fuel to maintain them simply won't be allocated to unproductive places like citys.

Jacobs said nothing of the kind.
She pointed to good design, and why it is good, where it is, and how it happened.
She pointed to bad design, and why it is bad, where it is, and how it happened.
She took into account both large and small scale economies, transportation, zoning, class and race mixing, work and recreation, public spaces and the environment.
She proposed policies to preserve and encourage good planning, and suggested ways to fix bad planning.
All of this in 1961 - ten years before the pope suggested somebody might want to look at the problem.
