Technological interventions, like the nano-guitar, might be operating in the background, unknown and unknowable to us. They therefore do not become objects of experience—and what is no object of experience remains unrepresented and does not prompt the formation of a conceptual image of its working. To the extent that they remain in the unconsidered and unconceptualized background of our actions and lives, these technologies are much like brute and uncomprehended nature—instead of knowing them, we merely know of them. Their looming present and potential efficacy does not appear as an extension of our freedom or our will, but as a mere constraint, even perhaps as a threat. Where technical and intellectual control come apart, the humanly induced workings of technology no longer signify mastery of nature but take on the character of nature itself.
