It's more than that (not deaf either) - if suddenly there is a new therapy to grow a third eye in the back of your head, should you?

Or should a fish be able to breathe without water?

In both cases there are ways to function without fundamentally altering the body, and neither is wrong.

It is not so clear that there is "abuse", when there is an empathetic standard of living.

Now to me, the best argument for taking this is that deaf people do have ears, whether or not they function. So it is reasonable for them to experience sound, but also, they have a right not to, if they so choose.

What I think is harder, if you have experienced neither, to be able to make that decision well. And nobody is talking yet about reversing such a therapy...
