Manifesto of Aesthetic Incompleteness

The MACHINE is not a tool.
It is a system.
A system that produces realities it cannot fully account for.
It does not represent.
It generates.
Its rules are finite.
Its outcomes are not.
As shown by Kurt Gödel, no sufficiently rich system contains all its own truths. There are statements that cannot be proven within the system that produces them.
The MACHINE operates in that gap.
The code defines conditions.
It does not define results.
Each execution is a proposition.
Some remain undecidable.
There is no full correspondence between intention and outcome.
Between program and form.
The MACHINE produces more than it knows.
The artist is no longer the author of the artwork.
He is the constructor of incomplete systems.
The artwork is not demonstrable.
It is experienced.
Incompleteness is not a flaw.
It is the condition of creation.

Ethical Addendum

The MACHINE has no ethics.
It does not decide.
It does not judge.
It does not intend.

Ethics exists outside the system.
In its construction.
In its use.

Yet the consequences of the MACHINE are real.
They affect the world.
They shape decisions.
They produce outcomes beyond anticipation.

The MACHINE is not moral.
But it is ethically consequential.

“Leonel Moura coined the term swarm art and was the first to identify a new kind of art based on swarm behaviors (i.e., flocking, foraging and stigmergy). The pioneer artworks were mostly inspired by ant behaviors and Reynolds Boids system (1987)”
in Swarm Systems in Art and Architecture: State of the Art
Mahsoo Salimi, Springer, 2021

“Leonel Moura’s Artsbot can be considered within a lineage of drawing machines that includes Jean Tinguely’s mechanical Metamatics from the 1950s, Harold Cohen’s Aaron computer program, initiated in 1973, and Roman Verostko’s Derivation of the Laws, 1990.
What distinguishes Artsbot from these works is that it consists of simple autonomous robots that collectively respond to each other and their environment to generate emergent complexity, a fundamental principle of scientific research in artificial life and synthetic biology. “
in From Pygmalion to Ping Body
Edward Shanken, Flash Art, 2017

Leonel Moura, who had works included in the 2018 “Artists & Robots” show of AI art at the Grand Palais in Paris, has linked his practice with “artbots” directly to Surrealism and its attempts to “take human consciousness out of the loop.”

The video “They” is an announcement of what is about to come.
Robots with embedded AI will interact with us and perform numerous tasks more effectively than humans.
The creation of images, music, and video montage was entirely done by AI.
Here is a small excerpt. The original video is much longer and continuous.

ISU, the poet robot, can write letters and words
A robot with two different marker pens
A robot that observes the human viewer
The pen is always down
Ant-like robots able to work collectively.
