I enjoyed the parallels made between computer diagrams and cities - how similar they are in their depiction and design but also their core differences.
Cities and computers are similar in the breakdown of processes for their standardization and optimization. Streets are designed for optimized traffic (hopefully), the same way a computer diagram is visually designed to facilitate the understanding of the workflow of a computational system by reducing to simple digestible chunks akin to streets. That’s why a map of a city and a computer look similar. However, city life goes beyond that, and the inner workings of a computer system are more technical and difficult than the diagram.
However, cities and computers are intrinsically different. A computer is a machine designed to perform a task, cities are the result of human cooperation, but they aren’t programmed as no human being can be truly forced to operate within a set, predictable framework.
