future of medical technology applications

future of medical technology is not cloning organs and transplanting them in human body 

or cloning arms and legs and attaching them to human body 

future of medical technology is organs repairing themselves and/or new organ growing in human body, replacing old organ 

and arms and legs repairing themselves and/or growing out 

regarding mental disability, the brain will repair itself and new functions in brain will grow, giving mental ability where it was previously missing 

the mentally disabled patient will grow into the new functionality in it's brain like a baby grows into a child learning to talk, learning to walk, 

like a child grows into a older child learning to ride a bike, learning to read, like an older child grows into a teen learning complex behaviour 

and so on until the patient has achieved full functionality of it's brain

human that damages it's brain will go through similar steps when brain repairs itself 

the important thing is preserving the personality/consciousness during repair and growth of new functionality of brain, 

memories could be moved around 

exotic technologies involved in these medical projects are beyond sensitive and different countries behaves accordingly
