I'm not paranoid...much. But I definitely wouldn't want a tracking device implanted in my body. Embed the chip in a bracelet or make it possible to insert in a shoe or sock or something. Then I might use it on my kid.
The whole cortical implant so I can upload the library of congress bit would be cool, but I think I'd wait until the first guinea pigs..er, I mean volunteers got all the kinks out.
