Though created few decades ago, cyberspace is deeply penetrating into our social and ethical mainstream. Reducing life to a non-physical environment, cyberspace serves as a proper application of some distinct posthuman ideals. A disembodied realm which supposedly liberates us from biological constraints, challenges strict forms of dualism and radically alters our sense of boundaries, cyberspace provides us with a rare opportunity to experience a posthuman future where we deliberately abandon our bodies. Still desirable though with its many defaults, cyberspace proves to be a barrier to regulations. It exposes inherent limits and effectiveness of our contemporary legal systems especially in fighting digital crimes. Filtering our human features not only our photos or videos, cyberspace represents a primitive posthuman scenario in which technological innovation would bring about the end of humanity as Posthumanism predicts. A posthuman novelist, Dan Brown, in his Digital Fortress (1998), suggests more realistic scenarios for human extinction. He exposes a posthuman concern regarding digital crimes and agitates contemporary sensitive debates revolving around fake identities.
