Cochlear implant is complicated procedure with chance of side effects. I personally know people that got it taken away again. And it has only 30 or so channels, enough for speech but not sure it's better than my current hearing with aids(I love music). It is far from sure thing that the cochlea is the best place to stimulate te nerves.
