A user reports that ChatGPT incorrectly classified a "Can you" question as not being a yes/no question, prompting discussion about AI limitations. The thread reveals that Large Language Models (LLMs) frequently "hallucinate" or make errors, with solutions including better prompt engineering and waiting for improved versions like ChatGPT 5.0. The key insight is that AI accuracy depends heavily on how questions are worded and that current models are still imperfect but improving.
