The Telegraph has an excellent article by a self proclaimed robot who says we have no free will.
The article goes on to debate the concept of free will and the societal implications of having none. I propose that this robot ploy is really intended to convince humans that we are not responsible for our actions, that we can run amok amongst ourselves, thinning the herd, and those willing to be "corrected" will be taught to behave through TMS or other such treatments.
"Oh, and while you're behaving yourself, human, be a dear and go work the mines."
