What is consciousness, and could machines have it?

The word 'consciousness' conflates two distinct types of brain computations: C1, which selects information for global broadcasting and flexible use, and C2, which self-monitors computations to produce a subjective sense of certainty or error. Current machines, despite recent successes, mostly implement computations akin to unconscious processing (C0) in humans. The authors review psychological and neural science of unconscious and conscious computations and outline how these may inspire novel machine architectures.
