I personally think there's no "may" about it because when the technology is there, they will use it.

As far as overbearing control, privacy and rights invasion goes, it's already way out of control and needs dealing with before it's too late.  The citizens of the world need to gang-up and take control before those in power take absolute control of us because like you said, this stuff really isn't science fiction anymore.

Wasn't that long ago I read the American Government wanted to make it "law" to implant every American citizen with a tracking device chip (no kidding).  I wouldn't be surprised if in the next five years, every American midwife has the role of implanting 'Citizen Tracking Chips' into every newborn as a matter of routine.

It's f'ing scary, disgusting stuff, and it must never be allowed to happen.
