There are two primary approaches to creating something: bottom-up design and top-down design . Top-down design is often seen in architecture. People do not build bricks randomly; instead, they follow the design drawings created by the architect. This method executes a plan that has already been established. When asked why something is built in a certain way, the answer is usually that the blueprint dictates its design. Conversely, bottom-up design does not start with a fixed goal, but rather involves setting and implementing small, actionable rules. For example, termite nests follow this approach. Small termites have a simple rule: to pile up soil. They do this without knowing the reason, but over time, the finished structure is remarkable and sophisticated. The appearance of the Sagrada Familia church , designed by Antoni Gaudà and still under construction, closely resembles a termite nest, differing only in size.
