AI vs rule based

This is an argue that whether AI or rule based is better. From my opinion, the answer is simple, it depends. For example, if you want to convert an unstructured text document, from .md to .txt, usually using AI is smart.  However, if you want to batch convert them, rule-based tool is the best solution. As an engineer, dealing with the cost and the performance is critical, and for the software development, it is usually token-sensitive. So, the problem is if you want to write a script or you want to rely on LLM to help yourself. While I personally prefer systematic solution, there is no universal correct solution.
