Let's compromise instead of bickering about this.
I wear a Cochlear Implant, but I don't always understand speech. I fare well with my own family members and friends that I've known for years, but for strangers--- I can't understand them.
It may work for SOME people, mostly late deafened adults who already know what sounds are like and they adapt easier.
It works for some, for some it doesn't and let's leave it at that. The research that "proved" that it works well probably had more late deafened adults wearing CI in their study group.
But for the deaf culture, we use CI as an assistive device or even accessory perhaps.
A lot of people I know who have CI, they either got rid of their CI or just use it to help themselves lipread better.
Let's end this bickering right now and be friends again.
