The post argues that programming is not only about writing code but also about being able to read and understand it in the future, so we should aim for simplicity. It contrasts three common stylesâspaghetti code, objectâoriented code that often fails in practice, and functional codeâwhich forces us to write small, pure functions that take an input and produce an output, usually in a single line. By chaining these functions in a simple list or array, we get a program that is easy to inspect, debug, and extend, because each functionâs name reveals its purpose and the flow of data is clear. The author encourages building programs from such simple functions without learning a new style; just use the functional approach to make future selfâs life easier.
