Answer
They complicate maintenance and understanding.
Deep inheritance hierarchies can make understanding and maintaining code more difficult. Each level of inheritance adds complexity, and changes in superclass can have unintended effects on subclasses. This can lead to fragile code that is hard to refactor. It's often better to use composition, where objects are composed of smaller parts, allowing for more flexible and maintainable designs. For instance, in an e-commerce system, instead of having a deep hierarchy of product types, consider using interfaces or composition to add functionality.
