While robots may eventually take over some police work and warfare missions, they will never fully replace the soldier and the law enforcement officer.

The reason is that the powers that be (TPTB) receive pleasure in stampeding the peasantry to war.

Kissinger was quoted once as saying that power is the ultimate aphrodisiac. Along these lines, the question arises as to what is power? Do you feel powerful when the toaster cooks your bread for you? Wouldn’t you feel much more powerful were you to, through shrewd cunning and deception, compel an individual to, of his own volition, willfully cook the bread for you?

Follow this line of logic to its furthest terminal and you'll discover that warlording may be the ultimate expression of power. Let's look at a couple functional definitions of war.

War is an economic flywheel by which a debtor government (The USG) destroys its creditors (The Japanese, Saudis, Russians and Chinese). It is also a means of rapid sociopolitical marriage of two or more cultures. Finally it is an exercise by which old elites demonstrate their power to, through use of rhetoric and high mischief, inspire the wholesale slaughter of young peasants by other young peasants, and thus to ritualistically sacrifice them to whatsoever gods desire the bloodshed, albeit Moloch or the god of “monetary-economic necessity.”

These being the true definitions of warfare, it becomes obvious that robots will never replace soldiers to fight the wars abroad or at home. Also, if these are the true definitions of warfare, then superficial concerns about ethics remain strictly the jurisdiction of politicos and lawyers. To suggest that the elites care whether or not killer robots kill civilians indiscriminately is beyond absurd. Look at the Bush-Kissinger-supported Pol Pot genocide of the intellectuals as an example of the reality that ruthlessness is considered a sign of strength among those truly engaged in global power broking.

No, robots will be employed for primarily a minimal of special missions. One reason why the number of such missions would be kept low is to, of course, restrain the growth of power spontaneously vested in the geeks who will program and oversee the functioning of the terminator machines. Another reason is, simply put, more euphoria is to be experienced ordering stupid humans, who have but willfully decline to embrace their free will, to kill each other en masse than is experienced watching intelligent machines destroy each other because that is what the technocrats programmed them to do.
