The more I read, the more I feel sad and worried over the future that is coming. I don't know if am just the wrong type but I think the fun in this world is because of the high and lows. Perfection isn't something I expect so much and to even consider perfection by a marriage of human and machines would have disastrous effects on humanity. There's a reason why you love certain people and not really love some others. There is something about them that keeps your closer but when I compare love and happiness with your text above, I think at some point in the future we'll lose what makes us human in the first place.
This is the risk we are continually running but it is not a future risk, it is in the present. So many people act on automatic pilot now that there is actually little difference between human and machine already.
