Not really. I cited insects as being a very successful non-emotional bio-organism as compared to humans having demonstrable emotions. Where does the difference occur? If you are visualizing some mechanical "arrangement" producing the ability to feel emotion, you are on the wrong path, IMO. I introduced insects and more advanced species as an evolutionary ladder toward the ability to experience emotions in living organisms. Lets look at the differences between insects and humans to see what humans have which allows us to experience emotion. Once we know how "emotion" is generated in biological organisms, we can look at ways to build this into AI. AFAIK, there is no machine which displays true emotional (chemical) responses. Look at mechanical arrangements in machines all you want. That's not where you are going to find the secret of emotion. Before you can artificially imitate life functions, you better understand what it is and how it functions in organisms which DO posses these life functions. We cannot magically invent our way out of these physically reactive biological functions. We need nature to teach us!!!!!
