AK,
Humans are already more "borg" like (StarTrek) than they may to care to admit:

Optics enhance vision, embedded microchips allow basic vision, hearing aids enhance hearing, radios enhance communication, gps overwhelmingly enhances navigation, orthopedic surgery builds/rebuilds skeletons, plastic surgery implants correct natures mistakes (one of my favorites ) and this here internet forum/chat room is a crude beginning of the "hive mind" and your being able to connect to the "collective".

That which is now "mounted" on the outside may well work its way to the "inside" over the next 100 years.
