In Moon, the blurring limits between natural and artificial beings are depicted by pointing out tensions and complementarities experienced by the main characters: Gerty, a robot, and Sam Bell, a clone. The cyborg issue underlies the issue of technologically manipulated biological organisms designed for labour exploitation. Moon thus articulates two urgent debates in contemporary societies: the use of the bioengineering in advanced capitalism and the role played by an ever-growing undocumented and criminalised labour force.
