The Future and Cyborgs...

It's hard for me to believe that there will ever be a practical use for or even the creation of the types of robots we see in Robocop or Terminator. That said, I can totally see the use of cybernetics becomming more commonplace and more significant in the medical field. It is reasonable to me to see things in the future like we see in Star Wars; not necessarily on the scale of Darth Vader, but definitely things like Luke Skywalker having a new hand crafted for him, or how Jax from Mortal Combat has two mechanical arms.

One of the questions I have is if our technology will be limited by physical constraints or if there will be ethical/political boundries, like there have been with stem-cell research, stopping us from developing the most out of cybernetics...
