In Gibson’s “Burning Chrome”, I found the references to replacement body parts to be very interesting. Although not quite advanced, in recent years there have been developments in many prosthetic devices. This includes, of course, the arm which was referred to during many parts of the story. The arm is mentioned to be extremely high-tech, with connections to nerves of the user’s body, for direct control; arms, like this are being perfected everyday now, to improve the life of the one who needs it.
We are not yet in “cyberspace”. The world is not yet ready to enter technology the way it is in Gibson’s work. We may not be cyberpunk, but we might get there in a few years. With the way technology develops now-a-days, we might reach that point in fifty years or so. Even then, I don’t think the world is yet ready for such endeavors. When is it too much?
