How much of the human body can be replaced by machines?


Answers:
My guess would be everything but the brain. Something can be put in for the heart to continue the blood pumping, same near other things..

if you wanted to be all SciFi, one day I'm sure you could own every part of your body, stomach, etc.

But "today" I think most of the basic stuff that doesnt involve TOO much technology..
I see this more as a question of at what point do we stop mortal human and become something else. Can a machine house a human soul? Do we begin to loose our free will as in the baggage of the Borg in Star Trek TNG? It is not so unusual to look to Sci Fi for a glimpse of our future when you consider Jules Vern and all his imaginings that enjoy come to pass.
Pretty much anything except the Brain.
almost everything , i read this article give or take a few a blind person who had the sight piece of her brain replaced by a robot, but it's quite dangerous so they dont use the technique of replacing parts of the brain in hospitalls. She call herself robochick!
all but the brain. kinda scary huh?
All including the brain.
Not yet, but someday.
Even if they are able to replace the 100% of the body by machines someday, they'll not have any access to the soul which is the real traveler within the body, of course unless they take to the process of self realization. Source(s): www.krishna.com
