[Suburbia] represents, after all, the greatest misallocation of resources in the history of the world. We built it during our most affluent period of history, and in the decades to come we will be comparatively destitute collectively. In short, we will not have the resources to retrofit most of suburbia.

In many places, the zoning prohibits the mixing of retail and residential. This stupidity has been accompanied by stupidities in municipal policy, such as disallowing accessory apartments - under the theory that renters are incapable of behaving decently.

I'm serenely convinced that we are heading into what will amount to a time out from technological progress as we know it.

We don't need gold plated highways. We don't need zoning commissions which penalize offices at home and promote car commutes.

We could do some household and neighborhood or town wind energy. But even this will run up eventually against the problem of needing an underlying fossil fuel economy to fabricate the hardware. Same with photovoltaic (solar) energy. We're going to be disappointed by what these things can do for us.

I do not believe we will get to Ray Kurzweil's proposed "singularity" in which human minds meld with machines to produce, in effect, synthetic human evolution. Our basic problems with maintaining the electric grid argue against that fantasy.

The public realm in America has two roles: it is the dwelling place of our civilization and our civic life, and it is the physical manifestation of the common good. When you degrade the public realm, you will automatically degrade the quality of your civic life and the character of all the enactments of your public life and communal life that take place there.
