input: Write a function that creates an AI-based chatbot in Python that can answer simple queries about a product or service. The chatbot should have a dictionary of predefined answers for specific questions and should randomly generate an appropriate response for unrecognized questions. If the user types 'Goodbye', the chatbot should terminate the conversation.
