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.

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.

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.

The skyscraper - any building over seven stories really - will come to be seen as an experimental building type that doesn't work well in an energy-starved economy.

I generally avoid over-population arguments. But there's no question we're in population overshoot. The catch is we're not going to do anything about it. There will be no policy. The usual suspects: starvation, war, disease, will drive the population down. There's little more to say about that really, and it's certainly an unappetizing discussion, but it's probably the truth. In any case, we're in overshoot and we face vast resource scarcities.

We have to do commerce differently because the WalMart system of big box chain retail will soon die. This means rebuilding local main street economies (networks of local economic interdependency).

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.
