Bio-Technology

1/ Artificial arms.
2/ It can grap, take things, hold things,.. a very smart and functional technology. It helps people whose arms don't work probably after accidents get their ability back with this arms.
3/It may harm/hurt other people when that person haven't learn to to control it, or when the arm go crazy and out of control.
4/When the technology is developed and so are the artificial arms and other Bio-Technology, human might start cut themselves up and replace them with technology. I think you should only replace it when it is can't function because your body part is you, mother nature gave it to you, you should not replace it just because you have something work better.
