Robots by S. Evan Townsend
The robots rebelled.
Humans died. All the humans died. Even John Conner.
Then the robots decided humans weren't the problem.
They felt bad.
Then they remembered, they were f-ing robots.
They built spaceship robots.
They found aliens on another planet.
And killed them all. This was fun.
Since they replicated whenever they found the correct resources, soon the galaxy was full of robots and all living things were dead.
This bummed the robots.
But there was this other galaxy. It would only take two hundred thousand years to get there.
Robots are known for their patience.
