Imagine a land called Nonods in which the people built a great many bridges. These bridges had a tendency to collapse frequently, however, killing or injuring a number of Nonods in the process. The bridges were also fairly rickety requiring lengthy training as well as many procedures to avoid falling off of them, significantly slowing traffic across the land. Now within Nonods there were many civil engineers who had amassed significant knowledge about how to build strong bridges that would not fall and that would support much more rapid traffic.
