We live in a post-industrial society. If production suddenly fails, sellers will begin to sell snow to the Eskimo, sand to the Arab Sheikhs and air to each other. And a mountain of doubting services to each other. In the meantime, you, dear technicians, will die of hunger. Your age has passed, your century has passed.

It is difficult to guess that without production there would be no post-industrial society, but any society that is not a cave.
