We have to make some things for ourselves because the conveyer belt from China is doomed (this process is known as import replacement). We have to do transportation differently, because mass motoring and even commercial aviation will soon be over. We have to inhabit the landscape differently because both suburbia and the metroplex mega-city will be obsolete, so we will have to return to a more traditional disposition of things in smaller urbanisms associated with productive agricultural hinterlands.

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.

We're still promoting stupid wasteful behavior in agribusiness - everything from ethanol production for cars to genetically modified crops. In commerce just about everything we do politically is in the service of WalMart and the systems tied to it. In transportation, we could, for instance, have compelled General Motors to produce railroad rolling stock as a condition of their bail-out, but we didn't do that. Instead, we're chasing the phantom of electric cars - and, believe me, we are going to be mortally disappointed how that works out.

I am far less interested in serving as a change agent than in functioning as a prose artist, whether it's fiction or nonfiction.

The ideas of [ Le Corbusier ] that actually found their way into practice were deeply destructive - for instance, the tower-in-a-park, which mutated into the vertical slums of the late 20th century.

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 think water transport will see a revival. However, we're not going to replay the 20th century. The industrial city of that era will not be revived. Our cities are going to contract. Many of them will contract as a whole but densify at their core.
