Cities To Triple By 2030

"Once roads (and sewers) are in place it's really difficult to re-do how a city looks," Seto said"

And once all the buildings are hodge-podged into close quarters, it is impossible to fit-in a really nice park, with kids playgrounds, frisbee-grass, picnic tables, walk paths, etc. ... all within walking distance of every individual in town.

[ Needless to say, the biggest cities SHOULD have several such parks, appropriately distributed.]

Every human being deserves the opportunity to have "a bit of nature" available to them each day, and such megalopolises (as described) will preclude that capability.

Was it not Machiavelli who first said : "We become what we think about?" (and many others have made it "their" mantra ever since...)

A little (city-planning) "pre-thought" could go a long way to shaping the society of the future.

Cheers and Blessings to one and all ~
