We have many reasons to be optimistic in this wonderful world. One reason is that we can communicate with people of like minds just about wherever they live on this planet.
Another reason is that around the world today there already exists just about all the technical knowledge necessary for us humans, as a species, to eliminate all the terrible curses which have afflicted us in the past. What we need to do now is to all work together and help each other!
