Looking over my three, I can see why most would be very reluctant to place me in charge of the world. If I had to sum up the why these three, because I would massively be discounting the lives of those in the present, for those in the future, not leaving them slaves to their ancestors past mistakes and pettiness.
1, An establishment of a ‘guaranteed wage’ economic system, where every human being on Earth has the right to the fresh water, food, energy, and means to shelter and self sustainability required to live at as best a standard of human development as technology allows. And a wage to purchase resources needed to pursue their own sustainability, including the right to operate as entrepreneurs and provide goods and services in exchange from others in mutually voluntary contract.
2, The abolishment of the ‘Nation State’ as we know it, and a return to self governing city states being the largest tolerated form of government outside my world spanning theocracy that has allowed me to enact this.
3, The establishment of a world agenda, that humanity must put the majority of its technological and industrial progress and development toward the establishing of permanent colonies, terraforming, and human modification, to expand human life and habitation throughout the solar system and beyond. Along with the development of cybernetics and artificial intelligence technology so that so-called ‘transcendence’ and ‘singularity’ possibilities for expanding human capacity and ability may be pursued.
