What are the pros and cons of a cybernetic hand?

These are the pros of prosthetic limbs and organs. The biggest pro to me is that it extends the human lifespan. It can really make a difference to the victim and the people around them. They could change the world. There is no limit to what people can do. The next most important pro to me is that it is a self-confidence booster. If they aren't confident, then they aren't being the best them and they wouldn't even want to live anymore. But the way that technology is going, almost no one is insecure because they are becoming more life like and advanced. Next, the usefulness of the prosthetics. If they aren't useful, it isn't worth the time of making more. Usefulness and mobility go hand in hand. In order for it to be useful, it also has to make you more mobile than you were before you got the prosthetic. Finally, prosthetics conserve energy. This is very helpful in elders because they don't have the energy that us teens have and that would really make things easier on them. All pros are connected in some way and some are more important in people's opinions about which ones are and which ones aren't.
