I am agreeing with you and I am a big believer in technology. Thanks for the links you posted. I also believe stem cells will be a major player in the next few years and within 10 years we will see treatments done to improve hearing.
Don't discuss other's quality of life, just discuss your own. I will say that I am thankful for great HA technology that has given me access to more sounds/speech. I will be thankful for great stem cell technology that will further improve on my hearing.
The truth is no one yet knows when clinical trials will begin for restoring hearing or to what extent hearing will be restored. It may be possible that a 20db restoration on hearing will be achieved in 10 years but could take 50 years for hearing to be restored to normal or even 100%. I am going to be realistic and ask for 20db improvement in my hearing. It's great if I get more than that but the first 20db matters the most as this is the point where my audiologist said I will hear perfect with HAs.
For instance, I hear at only 40-45db at 1000Hz but with a 20db improvement and with more powerful HAs down the road, im looking at hearing 10-20db at 1000Hz aided. Normal hearing is 25db or better. Of course id like more but I certainly won't be disapointed hearing better than 25db. An improvement is an improvement
