It only makes sense that over years of creating to serve an objective purpose that people would begin looking for things with better design. The book excerpt explains for a few civilizations, the pattern of creating things to suit a need and then improving the design of these things. This happens to be my general pattern for creating most things. I start with a simple, general design, and then I begin to move more specific as I add in design. It almost seems like a universal law since it is prevalent in cultures all around the world. As time passes, designers have become more and more aware of what needs to be updated, as well as creating new ways to be innovative.
