If most people’s “latent” taste was as good as they thought it was, we wouldn’t have so much “AI slop” - AI generations that are so-labeled precisely because the act of publishing them demonstrates significantly below-average taste.
There are definitely people who accept AI use generally who try to make “AI slop” a distinction within the universe of AI creation rather than a label for the entire universe of AI creation, but that seems to be a minority use of the term.
I don't think AI slop is indicative of taste. A lot of work doesn't care about taste at all. And AI slop is problematic in that it churns out an awful lot of output that people don't really care to review.
Taste is literally the thing which the concept of subjectivity exists to explain!
Obliviousness and uncaring will have similar failure modes, all the more so if both lead to rubber-stamping AI outputs to vague prompts.
