again - see my previous post. Can blind people VERBALLY communicate with the hearing world? If the answer is yes - then there is no double standard going on here. There's no comparison at all. It's apple-orange. Blind people ONLY need to learn how to use braille when reading.... in fact - they do not have to learn how to read anyway. They can just get by in hearing world just by listening and talking. Paralyzed people can do this too. Look at the world - it's full of illiteracy and yet - they can get by.
Deaf people cannot do this. They are at great disadvantage. We depend on ASL and reading. Something that hearing world don't do.
We've already see what happened to deafies when these wonderful technology were invented. What makes you think this biotechnology (which may or may not happen) can do a miracle?
Beside.... with advanced HA & Cochlear Implant.... why so many inconsistencies among deafies born-deaf? Kinda funny that this problem can be easily fixed with a non-technology tool.... it's called ASL
