How it scares and excites me at the same time! I love technology and everything it can (possibly) do. But on the otherside I feel like it makes us less human. On the turnside most changes are creepy and feels like you are losing something. I think it could be certainly needed for the survival of our race and further progression in evolution. The important factor here though is that it is not controlled by companies or governments for control such a stated in your post. Let´s hope for the best!
