Sometimes it seems that this is the direction in which the world is headed. First, it's permanent stone construction designed to last a thousand years. Next it's wood construction designed to last a hundred. Finally it's metal construction designed to last until it's built, almost. This triumph of the cheap, disfunctional, and ephemeral over the beautiful and permanent seems too often to be the essense of 'progress.' Capturing the progress of this march as documented by buildings, I find very interesting. Nice work.
