Killer robots that can kill without human intervention.
I find that impossible.
And based on the video, these experts IMO, would prefer the way wars are waged throughout history, in the recent past and presently with military personnel and equipment in the hundreds of thousands under total human control that kills and wounds and psychologically damages hundreds of thousands, completely destroys and rearranges entire countries/nations along with centuries of culture, customs and traditions (Iraq) causing the affected to basically start all over again because of human intervention and the thirsty government and corporate greed for ultimate power, command and control that failed miserably since the Vietnam War.
I just discussed the use of Predator Drones that many Americans complain that they are to impersonal and wrong for targeting specific enemy combatant individuals from a distance (and the fact that President Obama used them all the time) but IMO, it's more effective because:
For every unmanned Predator drone use to find, identify and eliminate specific enemy targets based on intelligence data, your eliminating the continued use of many military small unit, special operations forces personnel (teams ranging from 10 to 30 personnel), the use of all corresponding military logistics (a huge amount) needed every time for small unit sized missions including the use of expensive many military aircraft and/or US Navy/Army/Air Force/Marine assets (travel, refuel, maintenance and direct strike missions), the saving of many human lives, the non possibility of American prisoners of war or detainees and billions of dollars saved annually because using unmanned drones that multi-task, are reusable, disposable and replaceable are more cost effective and safer while being operated by military/civilian personnel tucked safely miles away out of harm's way.
And if drones weren't used, then the issue reverts back to issue of the number of dead or wounded military personnel and the losses of expensive equipment and millions wasted for doing the exact same thing that failed.
Cost of Predator Drone; program cost, estimated $2.38 billion and unit cost, $4.03 million (both annually) out weights the high possibility of high valued targeted missions not being completed, the high loss and wounded rate of military life conducting those missions and the negative aftermath that follows...that dead military member's family.
Everything can't be done (both) the George Bush's way; overwhelming military force for years in the hundreds of thousands of military personnel costing billions of dollars annually trying to find, capture or kill specific high value enemy targets.
Example: Close to a trillion dollars, ten years of war versus millions of dollars and several months of planning........Osama Bin Laden.
On the downside, manufacturing killer robots eliminate many US defense contractor jobs both public and private sector.
Killer Robots can't manufacture themselves, can't repair themselves and they can't program themselves to kill all willy nilly unless a human is involved in all aspects of it's operations and functions.
I'll assume that watching the "Terminator" movie and it's several sequels with the last one "Terminator Salvation" that displayed individual controlled killer robots in the thousands with a base computer that thought and made decisions on it's very own without human intervention (since the robots killed all the humans that built and controlled the computer) probably added to some experts's way of thinking but in the end regardless of which methods of war is more prevelant and effective in the future (or both), the same outcomes that always the end results will exist: scores of dead and wounded human beings in the thousands or millions, the overthrow and total command and control of all land, material assets and overall government control.
