The article casually confounds what it is programs do and how programs are written. Programs operate on data, and said operations can be more or less mathematical in nature.

A program is good because it meets a number of criteria, among which efficiency and math soundness are not always the most important. Many of the criteria have to do with how the human mind works and how it intuits.
