It remains to be seen just how extreme this sort of thing will ever actually get. I mean, piercings and tattoos have been around for thousands of years in one form or another, and they haven't really progressed much further than people getting parts of themselves pierced and tattooed that, um, really shouldn't be. I bet that when and if cyborg implants ever get this sophisticated, people will basically just get implanted with variations of stuff that's already in wide use - miniaturized cellphones installed inside your ear and jaw, subcutaneous iPods that you can turn on and off by winking, internet access in your brain - that sort of thing. I find it hard to believe that the police would EVER allow deadly weapons that are installed directly into your body, even for cops or soldiers - that sort of thing is just a horrible accident waiting to happen. And, of course, you couldn't get any of the REALLY extreme modifications unless you were willing to get a limb chopped off and replaced, which I think most people would be just a liiiiittle bit squeamish about. I can't see that sort of thing lasting for very long - it'd be a blip on the radar.
