Excessive polymorphism can lead to confusion about which implementation is being used at runtime.
In a complex system with many layers of inheritance and interfaces, it may become unclear which implementation of a method is being called, leading to bugs and unexpected behavior. For instance, if multiple decorators wrap a `Product` object, the final price calculation might be difficult to trace back to a specific implementation, leading to potential errors in price calculations.
