So you're trying to be a good developer and use type hints in Python. You even ask ChatGPT for help because, hey, why not? It shows you this beautiful dataclass example with Dict[str, int] as a type hint for your stats field. Looks professional, looks clean, you copy it. Then you actually try to use it and Python just stares at you like "what the hell is this?" Because—plot twist—you can't use Dict from the typing module as the actual type for field(default_factory=dict) . That needs a real dict , not a type hint. The type hint is just for show—it doesn't actually create the object. It's like ordering a picture of a burger and wondering why you're still hungry. Type hints are documentation, not implementation. ChatGPT casually forgot to mention that tiny detail, and now you're debugging why your "correct" code is throwing errors. Classic AI confidence meets Python's pedantic reality.
