A secret program in the United States seeks to replace human militaries with artificial intelligence-driven machines, but the machines aren't so willing to play along. *** Picture a world where humans no longer fight wars. No more families missing loved ones. No more veterans with lifelong mental and physical scars. No more conscription. For the super-secret End of War Project inside the United States government, such a reality is already here. The project models out how artificial intelligence can overcome dangerous and morally sensitive war scenarios with algorithms and automation. The centerpieces are "autonomous combat machines," or ACMs, that look like humans but function like supercomputers. After a string of brilliant successes in the field of combat, the End of War Project is preparing to reveal itself to the public, but something unusual stands in the way. Against their programming, the ACMs start exhibiting all-too-human signs of apprehension, guilt and compassion as they're pushed to perform ever more extreme tasks. The human leaders of the End of War Project race to find who "hacked" the ACMs, but what they find is even more startling--and revealing--than they could ever imagine. ***2019 Watty Award Winner - Science Fiction***
