The World's End

Point of Divergence
Newton Haven. 12th October 2013. 5 humans successfully caused an alien entity, called the Network, to have a nervous breakdown, destroying itself and its hold on countless planets across the galaxy, but at what cost? The Network's last act before its demise was causing an electromagnetic pulse, set off from all contact points, wiping out all electronics on Earth. The robot bodies (blanks) that the Network was controlling woke up, as the people that were copied, but there is a divide between the humans and the blanks, with the humans having hostile feelings towards them.
