What separates animals from humans is that humans can reason. Reason is what makes humans human, correct? For robots, there is no reason. There is only computing which is the correct way to do things. In other words, a robot can do something that receives more gain than loss. Where does this leave for us humans. Can we be grouped as some people are animals and others robots? Where does the label 'human' fit in? Us humans have evolved, robots as well, but not in the biological sense. Is it possible that us humans are evolving with the evolution of knowledge? If so, How do we know that what we bring to the world is good for the world and for us. Consider global warming, the first person who created the car and the group that created plants did not know what global warming or even the concept of it. In addition, how can we know what is ahead of us when the economy tells us what to think and by helping preserving the world we are destroying the economy. Consider if we were to spend as much money which is equivalent to the U.S.A debt to prevent global warming what would be the best choice of action? Help the world or help the economy? With this in mind the previous does this describe where the label 'human' fits in? Everything seems credible whether its in the TV, media and science. Where does our knowledge fit in? This is what i would ask to 'John doe' in the tv series of John doe. What i am really asking is that were we better off as caveman or what we are today.
