Why don all Deaf people have Cochlear Implants if they cure deafness?
Cochlear Implants are not a cure. They are also extremely invasive. There is an increased risk of illnesses such as Meningitis when someone has received an implant and of course there are lifestyle changes such as a prohibition from scuba diving past significant depths, etc, which require the recipient to make relevant life choices. Implants have blessed many people, especially individuals without hearing or sight. They don’t restore sound as we know it to a deaf person, but rather give someone a mechanical sound which they have to learn to re-interpret. Some deaf individuals love CI’s and others have no desire to have them.
