Exactly. We're already headed down that road.

If someone came up with artificial vision for the blind (like Jordy in Star Trek) would we prohibit it or embrace it?

If someone came up with a natural looking artificial hand for people who had lost a limb (like Luke in Star Wars) would prohibit it or embrace it?

Obviously we would embrace it.

The question becomes: would we allow the replacement of healthy body parts with artificial ones to "upgrade" them? Sight, hearing, smell. We'll be able to significantly improve them with implants in the future. But should we?

Good points, all.

As far as "But should we?"... Yes, we will.

There is a difference between restoration and enhancement.
I think it is ok to create ways to restore humans physically, so they can enjoy full lives.

Otherwise, the most we should be doing is creating the best environments for people to be their natural best.
