A fundamental question and my short answer is: with a new operating-systems for humanity.
We humans made a few significant mistakes in how to best manage ourselves during our evolution, something we must address to prolong our longevity as a species.
An ideal system of world governance begins with the realization the evolution of humanity is derived from an innate relativity theory (with sovereignty to each his own). A relativity theory like everything in nature, as Einstein discovered 100-years ago, combined with an implementation in which our meaningful differences define the strength of our evolution over our conformance to stale human dogmas.
Humanity shall not and ought not to be controlled or stimulated by governance deploying any kind of absolutisms, as such absolutisms are fundamentally incompatible with the innate relativity of humanity, as history has demonstrated time-and-time again. The latter kind of governance, as we can all witness, now seriously out of touch with the people it aims to serve.
Hence, we must redesign the systems of humanity around a relativity theory, away from today’s stubborn regurgitation of oligarchic control of freedom quite the opposite of free, and design a relativity theory for humanity purpose-built to enhance human strength and renewal.
I explain how in my upcoming masterclasses for policy-makers, not quite condensable to the format of a blog.
