Separation of concerns Memes

Someone really looked at their codebase and said "let's make one class do literally everything." Entity, DTO, Domain Model, API Contract, AND Kafka Message? That's not code reuse, that's architectural Stockholm syndrome. Sure, you saved yourself from writing a few mappers, but now your database entity knows about your message broker, your API exposes internal IDs, and your domain logic is coupled to JSON serialization annotations. Good luck explaining to the new junior why changing a Kafka field breaks the database migration. The tears in that meme? Those are from the poor soul who has to refactor this nightmare six months later when requirements change. Separation of concerns died so you could avoid writing three extra classes.
