Anything goes and nothing matters.

There is not going to be a "hydrogen economy," and no combination of alternative energy systems or fuels will allow us to continue the suburban pattern. It's finished. We will, however, desperately need to grow more of our food closer to home, and so the preservation of agricultural hinterlands is of great importance. But don't expect the fiesta of suburban construction to continue more than a few more years.

The cities of the future will be much smaller than they are today.

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.

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.

The two elements of the suburban pattern that cause the greatest problems are the extreme separation of uses and the vast distances between things

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.
