The carpenter no longer perceives the hammer — she perceives the nail. The hammer has become transparent, an extension of the arm, a medium through which the perceptual system engages with the wood. This phenomenon — studied by Merleau-Ponty, Polanyi, Heidegger, and others — describes the condition of skilled tool use. The mastered tool joins the category of media: like air or light, it is perceived through rather than perceived as. This transparency is the condition of skilled use and also the condition under which the tool's properties become most powerful and most invisible — especially when the tool's affordance structure is unstable, as AI tools' are.
