For me, it's really a case of it being ruined because someone told me an AI wrote it.
The content may be entertaining, emotional, and compelling. But I just won't view it the same way, because I am not in communion with an AI the same way I would be with a conscious, mindful human. There's no space for meaning because half of the author-reader relationship is missing.
A cynical mind would suggest I am seeking not the communion itself, but the rewards such a communion provides and they're probably right. If you lie and claim a human wrote it (and it is otherwise indistinguishable from human work), I will probably appreciate the work the same way I would a human-written work.
If AI were a conscious being, I don't think I'd mind that they aren't human, the same way I wouldn't mind reading the work of a space alien. There would still be a mind on the other end. But until and if that ever happens, if I know about it, I don't think it'll ever be the same for me.
