The Turing Test challenges machines to demonstrate intelligence and behavior indistinguishable from a human.
It wasn’t much of a challenge by 2020.
So, a new challenge was developed: The Pinocchio Test.
Artificial constructs were created with the goal of fooling themselves into thinking that they were human.
Robotic and biological sciences reached that goal around 2050.
For a while, synthetic athletes and pleasure units were on the production lines.
Then law enforcement and super-soldiers.
After the robots took over, they kept a few humans in zoos and research facilities.
But in the end, they were a hassle, and eradicated completely.
