I loved what Shel and few others had to say in this thread. It has provided me some food for thoughts.
Dr. Graeme Clark invented CI because he wanted to 'fix' deaf people all because his dad was deaf. He saw all the communication difficulties his dad had and felt very sad for him. So he made a decision to find a cure for deafness in his father's honour.
His father was deaf, yes, but in that time, he was successful because he owned a chemist store and he could provide for his family. Lots of deaf were not encouraged to own businesses and whatnot. A shame this Professor does not look at it in this light.
