On Wikipedia i find 'It is argued that several up to now hopeless medical conditions might benefit from such procedure.[9][15]'.

Many people's initial reaction is disgust. Which i don't blame them for. But what if we can move past this? It might be a great medical advancement.

doesn't it just replace it with another (nearly) hopeless condition? success presumably means total quadriplegia - and this exacerbated most likely by 'total body rejection' - or maybe even 'head rejection' depending on who is in control!
