Don't spout off about something you're not knowledgeable about? Not trying to be rude it just seems like if you don't know how they work you shouldn't be declaring something a failure because of a poorly conceived test.
I said not convinced, as in my user experince was/is still not conductive to the hype I perceive. The prompt says 'Ask anything', how should one know basic arithmetic is holding it wrong? Btw it also failed all queries in my native language after assuring (in English) it can parse them. Just nonsense/gibberish. Guess this is also a well known limitation? Perhaps my expectations were too high.
