The difference is the intent and the background behind it.
Sure for maximum mass adoption the computer can out-research any human and just find the blandest set of rules which cater to the highest percentage of the majority.
What it still will have a hard time doing, and I predict it will be for quite some time - probably until we have quantum computers - is to come up with a new way of doing poetry which is not just copying what humans did but better.
I think of AI like it's China, they are super efficient in copeing things and gradually making them better and cheaper but the setup of their society makes it impossible to really innovate.
And yeah I'm saying that it's the setup, because in Taiwan they are able to innovate at a much higher rate.
