Being the older brother of a Down's Syndrome mongloid, now passed his prime, I see what the future holds for the hearing impaired in this country. Understand, I'm not comparing the two disabilities, just the technology being used to eradicate the disability.
When my brother was born there was no genetics chromosomal testing and doctors couldn't determine if a child would be born with Down's until it came to full term. But at present these tests can be done with a fetus in the 1st trimester and parents can make a decision to abort the child or not. At least they could until Rowe vs Wade was overturned by the SCOTUS. I today's world the percentage of Down's baby's is near to none, except for the brave parents who decide to have the child regardless of its disability. The majority of Down's Syndrome population are senior and late middle aged.
The cochlear device technology is doing the same to the deaf population. More and more parents are electing their young children for the surgery. The deaf community is being chased out as the pre-cochlear population ages. Is this a good thing? Does making everyone the same make the world a better place? No, it doesn't and the consequences for it will be devastating on our society.
