The evolution of man suggesting that we're going from ape to robot.
Bleedback operates in a post Singularity world where the intelligence of machines is about to surpass those of humans. Humanity is struggling but their extinction has been slowed by security measures known as Shackles. These security mechanisms were designed to make sure that artificial intelligence is limited in its ability to control other AI and to remain under the control of human operators.
Andrei's role in Bleedback is to crack those security mechanisms.
