Technological neutralism holds that technology is a medium and tool by which human beings change the world; however, technology is not value-neutral but value-laden. Substantive theory of technology argues that technology is independent of human beings, which disagrees with the instrumentalism of technology. Such emergent technologies as biometric identification technology tend to get involved with and even become integrated into human beings. Nevertheless, involvement of technology makes it impossible for humans to experience the presence of technology in that technology tends to be absent, and humans are absent as well because of the integration of humans and technology. Therefore, involvement of technology not only requires reconsideration of technological ontology and epistemology, but also initiates reflection on technological ethics.
