Indeed, there are whole categories of art such as “found art” or the abstract stuff that involves throwing splats of paint at things that can’t really convey the intent of the artist because the artist wasn’t involved in specifying how it looked in the first place. The artist is more like the “first viewer” of those particular art pieces, they do or find a thing and then decide “that means something” after the fact.

It’s entirely possible to do that with something AI generated. Algorithmic art goes way back. Lots of people find graphs of the Mandelbrot Set to be beautiful.
