I completely disagree with this. According to this, no code can be art. For instance, videogames.
It has been enough time since ready-made (Duchamps urinal) and found objects, djing and sampling, and concept art. Art is not only drawing beautiful illustrations since at least the 2 world wars.

This is exactly how many artists work today, with a small army of workers, even interns, to execute the plan of the artist. Even Rembrandt had people painting to produce more pictures. Another example would be architects: does the star architect execute everything, or do they have the vision and instruct their very large teams?
IMO it is all about the intent and interpretation of a human.
