what andreyf said. In longer words, what I meant was that as technology advances, we are going to see less and less of the distinction between it and our own skin, or our own blood. Our blood may not even be what we think of blood today, but a synthetic blend of water, nutrients, gases, hormones, protiens, and other items that our bodies need. For example, there was a time when everyone wore spectacles. That technology that improved the wearers' vision was obvious and on the face. Now some people wear contacts, which most of the time are invisible except to the wearer. In the future, our eyes will be replaced with advanced photo optics, night vision, and a frame storage rate much higher than our minds can currently comprehend. We'll play it back like Tivo today, which will also be a thing of the past as well. We'll just play movies on our mind. The goal of the technology is to make itself invisible -- an intangible benefit to the quality of life. The kind of quality you just "get" but don't have to quantify, because it is transparent.
