I don't know if that's a great way to judge its creativity—it was trained on an enormous dataset, so it would be hard to determine if something was actually new or cobbled together from bits and pieces it found elsewhere.
I asked it to write AC/DC's next song, and while I admit I led the witness a bit, I eventually got it to this as the chorus:
(Outro)
We're the kings of rock and roll
Our songs might sound the same, we know
But we bring the heat, we can't be beat
With Angus Young in his schoolboy suit
And Axl Rose, he sang with us too.
I've tried playing interactive fiction games with it and it's not bad, but not too great either. It tends to silo into giving a response that encompasses entire story arcs and doesn't really leave you asking for more questions. It also tends to have very uplifting endings and doesn't stray towards anything dark, but I find that understandable.
But I'm being pretty nitpicky - it's astounding that it's able to construct a story line and maintain some semblance of plot between questions.
