From The Singularity is Near,
Still Human? Some observers refer to the post-Singularity period as “posthuman” and refer to the anticipation of this period as posthumanism. However, to me being human means being part of a civilization that seeks to extend its boundaries. We are already reaching beyond our biology by rapidly gaining the tools to reprogram and augment it. If we regard a human modified with technology as no longer human, where would we draw the defining line? Is a human with a bionic heart still human? How about someone with a neurological implant? What about two neurological implants?.. [page 374]
Seem like crazy-talk? Just ask Dick Cheney.
