Do we need pain in artificial limbs? I'd say no. What's the worst that can happen? If you ruin the bionic, you can replace it. Walk through all the fire you want, all you're losing is money.
Well, we do need some sensation in it, like feeling if something is hot or cold, mechanical failures on external body parts could be easily indicated aswell but what about internal ones?
Like a mechanical lung or heart. They will have to have some backup systems just incase of failure, but you have to be notified about something like that pretty much right away.
I'm not sure that machinery fine enough to replicate organic movement would ever be cheap enough to be in widespread use. Worst-case scenario, it could end up being a class thing that only the wealthy or outright rich could afford. I'd imagine that upper classes being physically superior wouldn't do much to shrink wealth gaps, either.

That said I'd be fine with this to an extent, I mean we already have artificial hearts and I've heard stories of us being close to having functional prosthetic eyes, so I can only imagine bionic limbs on the level of Deus Ex being not too far off.
I would gladly get artificial organ and limb replacements if they performed better then what I have. The biggest interest I have is will it be possible to replicate the human brain?
Well, one thing that modern engineering can do and mother nature can't would be omnidirectional limbs. You can only move your arms and legs in a fixed direction and range of motion because of the joint construction. A mechanical limb would have a full 360 degree range of motion without any limitations.
And yeah, wish we were closer to being able to replicate the brain, but it should be interesting to see if we can develop an actual self aware AI or replicate our brain first, though, those 2 things are very closely related.
Artificial limbs can even create a sense of touch.
But they are not so good as to replace a fully healthy bodypart, they are only replacements for lost limbs. I'm unsure wether or not we'll actually come so far as to make mechanical limbs that could be superior to real ones, because as we all know, all things mechanical require maintenance. And technology this advanced probably needs to be replaced. Your real arms last your entire life, while a mechanical arm might have to be switched and maintained many many times.

Then it's pretty much just a question of money and willingness. If you're willing to pay for the rest of your life for maintanance and upgrades when necessary to be able to walk faster, see better and whatever else. Also, prostethic eyes that would enable you to just zoom in on things, take pictures, wouldn't degrade like biological ones as long as it doesn't malfunction and whatever else. I know I'd love something like that and would get one in a heartbeat if possible. :P
I wonder how long it'll be before synthetic spines/discs can be created and feasibly installed. If you can replace the spinal cord, you can replace anything, not to mention the obvious implications for spinal injuries.
I eagerly await installing wheels in my feet so I can cruise around without walking.

Ridiculous concept. Even if human augmentation was possible, imagine the bills for maintenance of the non-organic parts, the trips to the shop every now and then. AND FOR FUCKING WHAT ?! So you can lift 100 kilos or run faster ?!
