And I've seen developers come from doing Node green field APIs at Netflix to waist deep in a 15 year old Java application with Spring MVC and some underlying Struts yet to be removed and don't understand why debugger stopped going any deeper and they lost where they start 10 classes ago from shared modules.
Then they don't understand how refactoring a core message for alerting customer across the sight has tight coupling, wanted to something fancy and broke the key business features, try to argue it's better but a business unit just list functionality of it's product. Instead of researching, and coming up a plan with a team to refactor using TTD and Strangle Vine method from the legacy tightly coupled code, to a separate module with better testing and following SOLID principles.
