It pays to remember that societies get what they deserve, not what they expect.

If the Internet exists at all in the future, it will be on a much-reduced scale from what we enjoy today, and all the activities of everyday life are not going to reside on it.

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.

The economy of the 21st century will come to center on agriculture. Life will be intensely and profoundly local in ways that we can't conceive of today. Economic growth, as we have known it in a cheap energy industrial paradigm, will cease.

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.

It is true that we need a consensus to go forward with restoring passenger rail in America, and often a consensus is formed by political action, via government. That is all true. But we have no such consensus, and no one in government or politics these days has the will or the force of personality or perhaps even the understanding of the situation to get on with job of forming a consensus supporting rail.

If it happens that the human race doesn't make it, then the fact that we were here once will not be altered, that once upon a time we peopled this astonishing blue planet, and wondered intelligently at everything about it and the other things who lived here with us on it, and that we celebrated the beauty of it in music and art, architecture, literature, and dance, and that there were times when we approached something godlike in our abilities and aspirations. We emerged out of depthless mystery, and back into mystery we returned,and in the end the mystery is all there is.
