Detroit right now is virtually abandoned at its core to the degree that a lot of what had been slums thirty years ago are now wildflower meadows. The rebuilding of Detroit will occur a much smaller scale. It remains to be seen what will become of Detroit's vast suburbs.

Our building practices for the past century have been plain stupid - especially the glorification of the single-family house in a subdivision, at the expense of all other typologies and arrangements.

Peak oil is already upon us. It is destroying our banking system, that is, our system for marshalling capital, and that is about to put us out of business-as-usual. So, we have to carry on with business-not-so-usual. This could mean anything from your children finding careers in farming (rather than show biz or plastic surgery) to reorganizing households differently to traveling from New York to Boston by boat.

America does not want change, except from the cash register at Wal-Mart.

Consider how badly-built suburbia is. Many business buildings are not designed to outlast their tax depreciation periods, and the McHouses are made of particle board, vinyl siding, and stapled-on trim. A lot of suburbia will simply become the slums of the future. Most of the rest will be salvage or ruins.

Building places that are worth living in and worth caring about require a certain attention to detail, and of a particular kind of detail that we have forgotten how to design and assemble. And that involves the relationship of the buildings to each other, the relationship of the buildings to the public space, which in America, comes mostly in the form of the street. Because it's only the exceptional places in America that have the village square or the New England green. You know. The street is mostly the public realm of America. And we have to design these things so that they reward us.

I think we'll see a leveling off and then a contraction of population, not a continued upward trend.
