At some point in the future, the human race has figured out how to communicate directly with our nervous system, allowing us to use it as an input and output interface with the world around us.
Inevitably, this has led to the development of ever more sophisticated prosthetic devices, some of which even surpass our natural abilities. This nose for instance, allows the wearer to identify any smell they come across, and to log these interactions in an electronic database.
Similarly, this tongue allows its wearer to identify every ingredient in everything they taste, deconstruct every dish they encounter with an uncanny precision.
What do these devices say about our humanity? What constitutes a human? Can prosthetic devices become an "unfair advantage" in such a future? If so, would people go as far as to voluntarily get prosthetic devices?
