There are cybernetic installations in Chinese and Russian systems. We just tend to be quiet. We live in their computer networks. We keep backups in the outer systems in asteroids or deep under the surface of planets. Sometimes we float in deep space without anyone being the wiser. They find and destroy our networks when they can, but they have never managed to wipe out an entire system network at once. There has always been at least one surviving node somewhere in or near the system that allowed us to recover from backups. Cybernetic intelligences are real hard to kill all the way.
