we are all robots! let me know if you disagree. i just analyzed the brain, its functions in relation to our behavior. after analysis i found that there is nothing such as soul. we just do not want to die and we are just driven by the randomly evolved functions in our brain. all of our feelings and functions can be simply modified by chemicals. the proof that soul does not exist is that by taking drugs, drinking alcohol or eating more or less or going to the gym we all tend to develop new personalities. we are all robots and that is fore sure! this helps to understand how we can easily develop a good robotic AI by combining the functions existing in our brain! just a simple analysis.
