There's an old IBM presentation going around, from 1979, that says "A computer can never be held accountable, therefore a computer must never make a Management Decision." We know that humans make monstrous decisions in war; many of us remember seeing the Collateral Murder video, and everyone has at least heard of the Nuremberg trials. When humans make monstrous decisions, at least some of them, sometimes, hang for it. The computer here serves mainly to diffuse responsibility for decisions that would be made in any case. Who will hang?
