You can ask it about Nietzsche, and it will reply with wonderful and esoteric interpretations of his work, because he is widely studied and ChatGPT has ingested all the works of all Niezsche exegets there are. You ask it about Hölderlin, and quality drops off, because Hölderlin is not that well studied in the Anglo-American sphere, the majority of Hölderlin studies is in German. It's odd that it cannot translate what it ingested in German and bring it back up in English. And when you ask it about chemistry ChatGPT is totally lost because it has no idea about concepts, even though the concepts are explained in the textbooks it has read. Until there is a breakthrough that allows AI models to gain understanding all these models are plainly useless. One can tell - any graduate student in any of the sciences has read way less than ChatGPT but their understanding is infinitely better.
