Here’s the baseline. We have been living together in cities for more than 7,000 years. By and large, we used those seven millennia to hammer out some serious best-practices about cohabitation and transport in the urban theater and the importance of social fabric. We threw most of that knowledge under the wheels of the automobile shortly after we invented it and have subsequently suffered through a saeculum horribilis in the urban context. Our overenthusiasm for technology and our human tendency to suffer from short-term urban memory loss have further contributed to our zealous disregard for past experience.
