We lack anything close to an ideal distribution of communities and population

All one needs to do is look at this map to see that we lack anything close to an ideal distribution of communities and population. We are behind the 8-ball economically and this is partly due to population densities. It takes around 10K human beings living in proximity to enable the natural growth of occupations and professions that make for a vital community. I have advocated that the interstate grid be used as the transport matrix for walkable communities of up to 10,000 (I call them cyber-communities) clustered in groups of up to ten to create cyber-cities of 100,000 separated by green space devoted to recreation and agriculture.

A cyber-metropolis would be a regional cluster of ten or so cyber-cities.

The genius of this scheme is that a walkable, car-free community can be built in an area a mile square, a miniscule amount of space. A population of 100,000 could be served by an aggregate of  just ten cyber-communities. Creation along these lines would revolutionize manufacturing because the components would all represent new inventions and designs, from the matrix needed to make each cyber-community ecologically sustainable to the mass-produced but customized  elements of  structures and spaces within the cyber-community.

How do we begin to take what we have now, subservient to the car and oil, and morph it into cyber-communities?. We do it first by creating cyber-communities de novo, from scratch. When we find a gutsy entrepreneur who is tired of gadget-capitalism, the fun can begin.
