I did my research for a year before deciding on CI's, you need to do some too. And, do NOT let anyone pressure you into it.
Oh sorry if I left the impression, that I am personally affected. Actually I am a normal hearing person with great interest in that question.
My opinion: Don't bother with the CI. Baseballboy is right. Our brains are "mapped" while we are learning sounds at young ages, and once we get older, our brains can't adapt as well.
I am interested if it actually ever worked for someone.
In comparison with seeing, visual acuity which a child never had before the age of around 5, the brain can never learn to understand later, even with best possible refraction (glasses). That is called
Amblyopia.
For example, let's suppose a child has from 0 to 18 years, -5 dioptre, never glasses. Such things still happen in poor countries. With 18 he finally gets glasses with -5 dioptre. He would see a bit better. Anyway, he still wouldn't be able to see at least 70%. Amblyopia.
If that's not the same with hearing that would be somewhat remarkable. And perhaps helpful for a few people?
If you've been 100% deaf since birth, you've adapted to being deaf, you will always be a deaf person, so why bother trying to hear now, especially if the outcome is not going to be very good?
I can think of a valid reasons:
- you are going to or already became blind or sight loss
- it's interesting for the people who are deafblind right now

Also for the 100% deaf since birth case:
Under the premise that what I am asking is even possible and chances for success are high enough and disturbances not too much,
as a normal hearing person I'd feel, that even bilateral CI should be seriously considered. Even if you never can understand speech. From my viewpoint it's already a lot gain if
- you can determine if someone you can not see approaches you (someone behind you in line or someone behind you warning you not step into something)
- you can hear and locate cars, runners, bikes, siren, etc.
- it helps you with lipreading
- music perhaps
