“Consciousness is a special kind of neurological architecture. A network of complex feedback loops that make a mind aware of its own activity, able to modify and direct that activity. In a way, a conscious mind is like a simulation constructed by the brain—a simulation of itself, so that it can take its own activity and attention into account in its own calculations and adjust itself accordingly. It’s crazily complex. It’s something nobody’s ever been able to reproduce in a machine.”
