Like a kaleidoscope, it can be fun to recognize familiar patterns and beautiful colors, but it's nothing more than that: a toy.
What I look for in art is intent and human passion; for me, the excitement of suddenly getting a nice number out of a PRNG or a cool story out of GPT is a very different from experiencing a story passionately crafted by a human.
When I read an amazing story like the Iron Widow, I feel respect towards the skills of the author, excitement for her future plans for the sequel; I follow the author on twitter and maybe interact a bit, because I appreciate what that human made me feel.
I can't do the same for a GPT story, because even if it was generated from multiple human stories, there is no actual human intent behind it; no one to thank, and no one to blame in case of messups: it feels like an empty shell.
