Is It Ethical to Voluntarily Replace Human Limbs with Technology?

Approximately two million people in the United States are living with amputations, according to the Amputee Coalition. Someone is always in need of a limb somewhere on there body because they have gotten injured and have to have it amputated or they have a disease of some sort that has spread to a limb and have to get it amputated. In those unfortunate cases, people really need the Technology to replace their limb and function as if, whatever limb was cut off, behaves like the normal one. To have someone WANT the doctor to cut off a perfectly functioning limb, and replace it was some technology is just a crazy idea to me. I know I like my body parts, and if they’re functioning just fine I’m going to leave it that way. Plus it would be offensive to some people who actually need it but can’t afford it at the moment. I think the thought of voluntarily getting one of two or all of your limbs cut off for technology is ridiculous. It is your body and you can do whatever you want to it, but be real, why would you do that?
