The difference here is that an artist has control over the medium. Every letter was put there with intent, every stroke carries meaning. Deciding not to do these things can also carry weight, and even the decision to let chaos decide is a choice.

no they don’t. That’s my whole point that there’s artworks where the artist doesn’t have complete control over the end result, and it’s the point.

It’s been done by Cage, people using radios in musical performances, introducing animals into artworks, using the brush like an idiot (Pollock) to achieve these things; in more modern mediums, the entire genre of rougelikes rely on chance to have certain things not be completely fixed, and emergent behaviour is a valuable aspect of creating interactive worlds that contain automatons.

And I would gladly take pollock out of the artistic cannon if I could.
