Controlling a Super Giant War Armor with the human nervous system places a tremendous burden on the pilot, and the neural link alone requires a completely sterile environment.
This is why past pilots were all submerged in bio-pods, unable to leave for their entire lives.
However, the Nanomechanical Cluster offered a perfect solution to this problem.
A direct, external brain-computer interface via the Nanomechanical Cluster was all that was needed to connect the pilot's nervous system to the Super Giant War Armor. As a failsafe, Shen Feng had recruited over a thousand people for each War Armor. These individuals served as "co-pilots," using their collective nervous systems to share the immense pressure from the signal shock of piloting the machine.
A low-end copy of Jingwei's program was installed in every Super Giant War Armor. While not a true strong AI, it was more than sufficient for combat assistance.
