The Borg.
The Borg is a group mind....like progs, today.
I know people with esophagus transplants grown on sterile cartilage, people with joint replacements, people with grafted arteries. They are no where near to The Borg. I doubt the biomech arms, the implanted biomech hearts, the development of pancreas replacements or implanted artificial kidneys are or will be Borg, either.
