Perfectly okay for you to inquire, and since I am OP here that makes any hijacking okay....
I had normal hearing until the age of 11, and was stricken by spinal menigitis. As a result my auditory nerves were damaged and all my hearing was lost. Prior to the implant operation in early 1996, the doctors told me there was no assurance I would regain any type of hearing, their testing revealed I might, but they could not be sure. Although the operation was technically a success, any sound input provided to my implant was badly garbled...like you took an entire group of various sounds and jumbled them up and fed them into my implant.
So, what I basically heard was pure NOISE, with nothing recognizable. About lip reading--that is my only method of communication, and I am very skilled. Thankfully I was able to hear for 11 years, meaning I had learned speech, and was a very avid reader. Those who are born deaf must struggle to learn speech and reading...I was VERY fortunate in that regard.
I can well imagine what you and your friend discuss as regards the future...the way communications and electronics have rapidly advanced is just amazing. I have carried a Blackberry since 2001, and had someone told me in the year 2000 that someday I would be able to communicate with others, and surf the Internet anytime, anywhere, using a device that fit in a shirt pocket, I would have privately thought they were crazy.
