The pace of technological change is frightening, and touch nearly every aspect of our daily lives, but none quite so deeply as the field of cybernetics. That is, actually grafting technology onto our bodies. Beginning to merge with our technology, essentially becoming cyborgs.  Sound farfetched? It probably shouldn’t. Even today, we can use technology to improve nearly every part of our bodies, and what we can improve today, we can outright replace tomorrow.

According to Ray Kurzweil, the director of engineering at Google, the biological parts of our body could start to be replaced by mechanical ones as early as 2100. We’ll also be able to use technology to boost our brainpower by as much as a billion-fold, assuming that our brains (which are enormously complex computers themselves) abide by Moore’s Law, which states that the power of computers doubles, on average every two years. This, coupled with enhancements in the area of 3d printing are already rocketing us down that road.
