As technology and procedures improve and develop in future, users of cochlear devices might hear at levels superior to those with normal hearing.
Due to the expensiveness of the procedure, researchers might discover a biological solution and make this procedure obsolete.
Because of the relatively small applicable location of the hearing organ, new technology may become viable to implant even 10 times more electrodes as the current 24, as these components tend to decrease in size.
Recipients, due to financial considerations, do not upgrade their implants. However more sophisticated software enhances the quality of sound recognition more economically.
