It seems unlikely we will have any sort of effective governance for this (look at our current political system). At some point someone will invent AI that lets them gain an extreme advantage of some kind (financial, political or military). This accelerates current inequality and leads to revolution. Post revolution a new AI is created to manage earths resources for the benefit of all. Whatever AI is created will be flawed somehow and will eventually cause great damage to the human race. Alternative AIs will be created to improve or combat the incumbent AI and a sort of evolution of AIs will occur. Although AIs originally were created to optimize for the human race, survival of the fittest leads to AIs exploiting loopholes in their objective functions to find ways to replicate and hoard resources for their own survival. Humans will still be accomodated to some degree, but in more and more unnatural and distorted ways.
