I'm not the OP but I've been thinking about this for a little bit since I read your question. Part of me says no, what could be more Sci-Fi than a complete and comprehensive story written by a computer. Who wouldn't want Data to have been able to and succeeded at writing a story that connects with his human compatriots? On the other hand, I also understand the concern and feeling of "something lost" when I consider a story written by a human vs a machine.

But if I'm truly honest with myself, I think in the long run I wouldn't care. I grew up on Science Fiction, and the stories I've always found most interesting were ones that explored human nature instead of just being techno fetishism. But the reality is I don't feel a human connection to Asimov, or Cherryh, or any of the innumerable short form authors who wrote for the SF&F magazines I devoured every chance I got. I remember the stories, but very rarely the names. So they might as well have been written by an AI since the human was never really part of the equation (for me as a reader).

And even when I do remember the names, maybe the human isn't one I want a lot of "human connection" with anyway. Ender's Game, the short story and later the novel were stories I greatly enjoyed. But I feel like my enjoyment is hampered by knowing that the author of a phenomenal book that has some interesting things to day on the pains caused by de-humanizing the other has themselves become someone who dehumanizes others often. The human connection might be ironic now, but that doesn't make the story better for me. Here too, the story might as well have been written by an AI for all that the current person that the author is represents who they were (either in reality or just in my head) when I read those stories for the first time.

Some authors I have been exposed to later in life, I have had a degree of human connection with. I felt sadness and pain when Steve Miller died and left his spouse and long time writing partner Sharon Lee to carry on the Liaden series. But that connection isn't what drew me to the stories in the first place and that connection is largely the same superficial parasocial one that the easy access into the private lives of famous people gives us. Sure I'm saddened, but honesty requires me to note I'm more sad that it reminds me eventually this decades spanning series will draw to a close, and likely with many loose ends. And so even here, if an AI were capable of producing such a phenomenal series of books, in a twisted way as a reader it would be better because they would never end. The world created by the author would live on forever, just like a "real" world should.

Emotionally I feel like I should care that a book was or wasn't written by an AI. But if I'm truly honest with myself, the author being a human hasn't so far added much to the experience, except in some ways to make it worse, or to cut short something that I wish could have continued forever.

All of that as a longwinded way of answering, "no, I don't think I would care".

Very interesting!

In contrast, I think for me a tremendous part of the joy I get from reading science fiction is knowing there's another inventive human on the other side of the page. When I know what I'm reading is the result of a mechanical computation, it loses that.

But the real noodle-bender for me is would I still enjoy the book if I didn't know?
