I'll just throw a few ideas into the pot here.
To change the world for the better, and to strive for a truly STO environment I think firstly we would have to get rid of the education system as it curently exists. I mean scrap it completely and start from sctatch. Children from a young age need to be empowered with REAL knowledge starting with:
. Philosophy/Theory of Knowledge
. REAL history which would include the terrors of war/slavery/tyranny
. Psychology so that children can begin to get a handle on their own and others behaviour from an early age
. Social Anthropology. Teaching children the history and value of culturally different humans is crucial in my opinion to a STO environment. So much of the trouble on this planet appears to stem from an almost innate fear of
difference and the inclination to identify with a particular social/racial/religious group from on early age. Of course this is propagated by our parents and a multitude of institutions throughout our lives.
. Knowledege of Psycopathy/Ponerology pure and simple
. The crucial importance of treating all beings in the lower densities with the utmost honour and respect because of course we are all aspects of the Divine Cosmic Mind.
Of course this would all have to be tailored and made palatable to young minds at various stages of development! You get the idea though and I do honestly believe that a completely radical over-haul of what children are subjected to can give a 'better world' a fighting chance. After this, things become rather complicated because even after such an education (the ethics of which would have to be practically demonstrated by the adults in society), individuals are free to choose other paths which may be at odds with those that have been presented to them. We then have the issue which has plagued every piece of theorising on Utopia in history: What kind of bureaucracy/power stuctures must exist to regulate the system?
