I also have yet to experience an AI dev tool tell me, “I can’t do what you’re asking”. I wouldn’t mind stumping these things now and then.
@MrRooni I have gotten that quite a few times, and it has pleased me. (I think it's more often been "I really can't predict a very reliable outcome here, and I know you're the expert, maybe you should do this one yourself". But that's good too!)
