This is why I'm like "it works, and has worked for months(years) leave it alone and do better next time" to all the young engineers who like to sling around terms like bit rot (bits do not rot) and "technical debt". Technical debt is when the code becomes hard to comprehend or update, not just because of age or you know a new fancy dancy language or DSL of their own design we should be using. Also get off my lawn lol
