Propose an alternative architecture for your chatbot’s core conversation logic that leverages the strengths of the early days of AI research. Explain how this change would improve maintainability and scalability.

Replace the deep learning models with a rule-based system, using formal mathematical rules to describe the conversation logic. This approach would allow for greater transparency and maintainability, making it easier to debug and update the conversation logic over time. However, be aware that this change might limit the chatbot’s ability to learn from large datasets and adapt to changing user preferences.
