Yeah, the illusion is quickly dispelled once you spend any time with it. I was trying it out when I was doing worldbuilding for a story I was writing. If you ask it to name 20 towns and describe them it spits out a numbered list. Same with characters. But then I asked it to make the names quirkier and it just used the same names again and described all the towns as quirky. I also asked it to make characters with names that are also adjectives and then describe them. Names like Able, Dusty, Sunny, Major.

The first iteration had a list of names and a description but the description always related to the adjective. Sunny had a sunny disposition and a bright smile. I told it the description should be unrelated to the name and it did the same thing again. I told it to change the name but not the description and it still rewrite the descriptors to match the name but didn't change the structure.

Nothing I told it could make it move off the idea that a man called sunny must be sunny. It basically can't be creative or even random when completing tasks.

This is fine when writing dry material that nobody will read but if you want someone to enjoy reading or listening to what is written then the human spark is required.
