This goal encompasses concerns of environmental sustainability, economic sustainability, and equitable accessibility. Those concerns are table stakes, and must be included in any serious attempt to make our cities better. My thesis is that those concerns are not enough, by themselves, to radically improve our cities. We can, and should, retrofit our cities to make them more equitable and sustainable, but we should also aim to move our cities forward to a future where our built environment catalyztres our well-being and happiness.
