In this interview, theoretician and artist Chris Salter explains how immersion, for him, is not about the surroundings but about losing a sense of the distinction between the body and the environment or between the self and the non-self; he also considers that this current boom of immersion is due the changes in the structure of capitalism and an accompanying epistemic shift. His concept of “the fifth technology of sense” continues Foucault’s notion of technology as an organising force or strategy: he explains that in the twentieth century, we have lost our willingness to trust our senses but we trust numbers and instruments that are not interested in the human subject, and that the technological systems we are creating are completely alien to the whole of human consciousness or subjectivity.
