Obsolescence is the future, the imminent possibility of technology taking over, and the fear that humanity, society and nature will be replaced. This discontinuance makes the world evolve. A portion of these projects examine the concept of existentialism, or include creations that fall into the uncanny valley, where such behaviours and capabilities can be seen as humanoid. Futuristic-like pieces such as mechanical arms, motion tracking, coding, augmented or virtual reality also represent this category.
