Over the last few years I've seen many examples of LLMs being used for the same kind of problems as in this paper. While it's undeniably impressive for an LLM to do these things, it seems that often the fact that NLP existed well before LLMs is completely forgotten.
Additionally, while LLMs are of course capable of solving a much broader set of problems, it is often the case that all questions presented in a given demo could be solved using a small program such as this.
