As actual usage? I enjoy making stories up (or misremembering existing ones) for my daughter. The human touch is valuable to me. I also wonder: many well-loved stories of today started as a story the writer was telling his/her children; one example is The Hobbit. What if Tolkien had thought "screw this, I'm overworked and tired, I'll just type some prompt for ChatGPT and it will be enough for Christopher".
I know mine is a kneejerk reaction. But I can't help thinking that this is solving a problem no actual humans have. We know how to tell stories, good or bad. We don't need automation for this. We don't need help writing terribly bland and generic stories, either. So it feels vaguely dystopian to me.
Technically it is impressive. ChatGPT and things like it are the most impressive thing in years, to me.
