Survivor Diary: End of Humanity

In the world which has ended my name was Dr. Adrian Bonner. I was civilian head of the quantum computer lab at the DOD, under contract from Nexus Robotics. I have decided to keep this journal as a record of my thoughts on what has happened to me, and to the world. I do not know if anyone else is alive, but in case something happens to me and someone finds this, it may in some small way explain. Right now I am sitting in a coffee shop in Tucson called Bean There.
