Speaking as someone who was completely deaf, then half-dead and has been slowly losing his hearing over time, no. No, it's not worth it. Being deaf sucks, because very few people know sign language and when I tell people that I'm partially deaf they suddenly talk louder as if that's going to solve everything. As you grow older and hard of hearing, you'll also experience losses in the pitches that you can pick up, so Chop Suey now sounds great, but over time you'll be adjusting the volume higher to compensate for the loss in the pitch levels you can pick up, so you're just accelerating the process.
I would give anything, to be able to hear in stereo and without issue.
Also, with more people choosing to work past their traditional retirement years to 70 or even 80 years of age, having functional hearing at that time will be to your benefit. No amount of surgery will bring it back once those nerves are deadened.
Mine's just come round for the day to annoy the crap out of me for the next four hours. Sigh.
! Somethings are just worth suffering for. Music would probably be one of the best.
