What astounds me about this tech is just how quickly it is improving. It seems like it's at least once a month that I'm reading about some grand new breakthrough in prosthetics. It's weird, I remember when Deus Ex: Human Revolution came out I was thinking "This is really cool, but they set it a bit close to be believable. It'll never be there by 2027."
At this rate it might be 5 years earlier than that.
