Most people are capable of building systems that are twice a complex as the systems they are capable of maintaining.

This is most of IT right here. Kubernetes, containerization, most any project, some “rockstar” person designs something so complex that even they can’t maintain or repair it six months later.

Meanwhile, I am over here being laughed at for designing my simple “toy” systems that keep working, and that a helpdesk person with six months experience can fix if needed (and it’s always needed).
