jmd's theory sounds plausible.

I've also heard the interpretation that since she is a full body prosthesis, it is meant to illustrate the detachment she has to her sexuality which sounds plausible although I hate to read too much into literature.

Might just be titillation, Japan is certain not shy about injecting sex into its anime. According to here, the manga series creator had a history of sexualised manga prior to GitS:

I think this is a lot cooler than it sounds....so
*promote "cheap" stylish futuristic bionic prosthesis.

I'm not worried about a loss of humanity or w/e - Are amputees somehow less human because they use a prosthesis? I don't think so.

I'd be more worried about a divide forming between those that can afford to enhance themselves, be it through implants or some sort of genetic modification, and those can't. One would hope that this technology would improve the lives of all humanity and not create a society with a rigid hierarchy with almost no social mobility.

From the article:
For Barnes, the device needed to be able to take cues from the human body. The lab designed a prosthesis that uses a technique called electromyography to pick up on electrical signals in the upper arm muscles. By tensing his biceps, Barnes controls a small motor that changes how tightly the prosthetic arm grips the drumstick and how quickly it moves, vital skills for a drummer.

The researchers then added another layer of complexity: a second, autonomous drumstick on the robot arm (see photo). This second stick, controlled via its own motor, uses a microphone and an accelerometer to sense the rhythm Barnes is playing, as well as music from any nearby musicians. An algorithm then produces a new beat with a complementary rhythm and melody, modelled on the music of jazz greats like John Coltrane and Thelonious Monk.

With this extra artificial intelligence, human and machine combine to make Barnes a kind of "superhuman drummer", Weinberg says.

My first thought: This looks shitty for an expensive hand prosthesis. But it's meant to be simple and robust as well as easy to rebuild.
No sensors are build in, it works a lot simpler: By bending the wrist fingers flex.
As far as I understood, design will be in public domain in the future.

Hair prosthesis will help you if you get cancer, you selfish whiner.

That's a very realistic-looking left arm prosthesis he's got there.

I've heard about cases like this. They are usually caused by an infection. I've seen one case where an old man's entire face is a cosmetic prosthesis except for one of his eyes. I think it was caused by a mold infection inside his nasal cavity and everything basically had to be removed to keep it from spreading. The strange thing is that the strain of mold was essentially the same kind that forms on old bread and it ended up inside and taking root in his nose.

A real important reason of why mold in the home is taken so seriously.

If you look closely at his right hand, you can sometimes notice a flesh-colored glove. It's a prosthesis - he lost most of the hand when a prop stick of dynamite exploded while he was holding it. And he still hung on to that clock tower.
