Show me proof the govt's using it to control me and I'll worry. So far it's good, they can use it to find deformaties and reseach all kinds of brain diseases. They could possibly find the causes of many diseases and cure them. As far as I'm concerned its would work better for doctors. Not the gov't who'd have to somehow set up the (I'm sure queer looking) device somewhere large enough and powerfull enough to control millions of people. Hard to conceptualize.
