What is the author suggesting? To write software using infinite loops changing global state? Makes sense for video games but not for the custom enterprise software where clean code practices are usually applied.
The enterprise code must be easy to change because it deals with the external data sources and devices, integration into human processes, and constantly changing end-user needs. Clean code practices allow that, it's not about CPU performance and memory optimizations at all.
