Selecting which outputs to post is not sufficient to establish copyright. See the copyright office's example of a piece of driftwood selected, polished, and mounted by a human:

503.03(a) Works-not originated by a human author.

In order to be entitled to copyright registration, a work must be the product of human authorship. Works produced by mechanical processes or random selection without any contribution by a human author are not registrable. Thus, a linoleum floor covering featuring a multicolored pebble design which was produced by a mechanical process in unrepeatable, random patterns, is not registrable. Similarly, a work owing its form to the forces of nature and lacking human authorship is not registrable; thus, for example, a piece of driftwood even if polished and mounted is not registrable.

Interesting, and probably somewhat closer, though I reiterate that here it is neither that he simply set up the process nor that he simply selected outputs. He did both, and both were creative portions of a single creative act.
