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. Setting goals and planning is one way to create, but actual achievem...
A bank trades collateral by holding debt called savings and selling bonds known as loans. Customer deposits are not bank money and must be returned to the customer as the bank’s debts. These debts lure customers; the bank lends money to them to recreate bonds with the customers’ debts. At this point, there is “collateral (mortgage)” to prevent the risk of bankruptcy between bonds and debts. In other words, banks do not possess the collateral; they merely govern it. The primary instrument of control is their bonds. In a way, banks tend not to be places where they make money with their own possessions, but rather conduct business as if it were their own with others’ collateral. Therefore, because banks need to know the value of secured collateral, the most accurate investigation of real estate and valuable gem information is key to banking. This is the similarity between a bank and a library that accumulates information. - Joseph’s “just my thoughts”
