Philosophically, questions are the tools we use to map the boundaries of our ignorance. True wisdom begins with acknowledging what we do not know. In modern computer science, even our most advanced language models struggle with this concept. While a neural system can easily answer standard queries, its accuracy drops significantly when faced with unanswerable questions. Recognizing when no answer is supported is a profound cognitive leap. A great question does not just seek an answer; it defines the limits of our current understanding.
