I also find this a bit creepy. I can't say I'm entirely against modifications, as the contact lenses in my eyes can attest to. But I only want it to the point where it's a necessity. If, later in life, I have to have artificial parts put me in to keep my heart running or my hip swinging, then I guess I'll grudgingly go through with it because to me the benefits are worth the artificiality of a few parts. But I just know I'd feel paranoid knowing there's a chip in me. Plus, artificial hips, as far as I know, are just manufactured body parts with similar functioning to the original. This chip, while not serving any purpose that keeps my body functioning, would contain personal data of myself in it. And I just don't like that. It'd be like being a barcoded item at the local grocery store. One quick little scan, and you know who I am and other information about myself. In itself, it seems rather benign, but there is so much more that could be done with that technology if it gains acceptance, like the Big Brother analogies used earlier in the thread. And who's to say that these current chips won't have that kind of power embedded in them? I just don't trust it. The only part of my body that I want information stored in is my brain.
