This chapter discusses the various areas of human enhancement application where such concerns arise, including physical (chip self-identification and payment, improving hearing with magnetic headphones, improving vision in the infrared spectrum, and use of chips for monitoring bodily functions), cognitive (deep brain stimulation, memory chips, manipulation of neurons and neural dust), and emotional level (mood-fixing, neuroprosthetics) and life-extending technologies (cyborg digital mind, cyborg digital body, cryonic preservation of the body).
