You don’t always have pay off the debt you created; you can work around it and avoid ever having to pay it off. Technical debt only hurts if you have to pay it back.
Anyone who has worked on a large enough codebase knows that technical debt is an inescapable reality: The more rapidly an application grows in size and complexity, the more technical debt is accrued.
In business, all human problems are also business problems,viewed with a wide enough lens. Unhappy humans are unhappy workers, and unhappy workers are less productive. Yet, this angle of technical debt is seldom discussed.
It looks like Facebook is getting the textbook results of ignoring code quality.
