I suppose it's a matter of how much you appreciate human achievement. Detroit could become the realization of a new Metropolis. Hyperloop could be built between Detroit and Cleveland and other cities with much less regulatory constraint. The promise of these mid-western cities excites me much more than the west coast because we do not need to be bogged down by preservation of natural landscapes there. They are the areas that could have delivered millennials from their stagnation if momentum had taken hold.

There is no choice but to grow. People like to travel, conduct scientific research, and face and conquer new technical challenges. You cannot do this without more people and the productivity they provide. Period.
