We like practical words like cost-effective, businesslike, profitable. Architecture tends in our times to serve these ends. An unprofitable skyscraper simply would not be built. An unbusinesslike drafting office would soon destroy an architect's practice. Yet ars longa vita brevis .
Values can change.
Art, myth, religions can bloom once again. We may, for example, want to rebuild America. We surely can if we want to. We can do anything. We have the skill, the materials, the labor force.
