This gallery of computer illustrated graphics is a collection vision of what certain cities will look like in the future. The main image, for example, is of Los Angeles, California in 2088. The page is full of different ideas by various artists of what our world will look like, looking specifically at transportation in many of them. Between the images are famous quotes about the future.
Think about it: the Stone Age did not end because humans ran out of stones. It ended because it was time to re-think how we live. We can only think of our future cities if we think about what our intentions are as a species. The Next City would use modern technology but focus on how to love all species, all the time. Everything would have to be designed from the molecule up, meeting all requirements of cost, performance, and function. It also means keeping ecological intelligence and social justice in the day to day.
