This is certainly interesting, but is anyone else even a little sad that the headline here isn't "The redesign of New York City's subway system"? (NB: improvements in design are real improvements, no disagreement there.) We have had so much progress in the world of bits, and comparatively little in the world of atoms, much to our detriment. The efforts presently underway to make new tunnels orders of magnitude cheaper excite me. The world below the ground in a city as old as NYC is fascinating, and there are certainly an astounding number of physical and social obstacles to extending the transit system there. But with the city so empty and facing such profound change, isn't right now the time to be thinking big?
