Robopocalypse - Daniel H Wilson

Two decades into the future humans are battling for their very survival when a powerful AI computer goes rogue, and all the machines on earth rebel against their human controllers. The machines believe that the planet would be better off without humans, and that robots would be better caretakers of the earth's ecology. The robot war wages for five brutal years, but in the end humanity triumphs.
Twenty minutes afer the war ends, Sergeant Cormac 'Bright Boy' Wallace is exterminating robots in the Alaskan wilderness when he finds a machine containing a an information cube - the robots' black box on the entire war. Inside are thousands of accounts of humans designated 'heroes' by the machines; from children to soldiers - those who fought, and those who died. A few individual robots also rejected the super-AI's homicidal campaign and join with human forces to save their collective freedom. Robopocalypse tells the story of humanity's battle to survive, with fry cooks and ordinary citizens battling rogue smart cars and independent-minded kitchen appliances, while government scientists take on murderous supercomputers.
