From Terminators and Cylons to the War Droids from Star Wars, military robots are staples of science fiction. But they’re already here in the real world too. The US, China and Russia are all investing efforts into military machines – but they won’t be the gun-toting humanoids we see onscreen. Would taking human fighters off the battlefield increase the peace? Or should we be gravely concerned about this new era of international war?   Today on Why?, Emma Kennedy speaks to Kelsey Atherton, an award-winning military-tech journalist and Chief Editor of the International Policy Journal.     • “Militaries are deeply invested in the idea that things flow from the top.... The more autonomy you give a machine the harder it is to put in command and control.” - Kelsey Atherton  • “If a robot makes an error, it’s on the person who programmed it… these weapons are brought to battle with errors built in.” - Kelsey Atherton    WHY? is written and presented by Emma Kennedy.
