the 400 year time limit for empires is expiring in the next 50 years tho, i think that it's basically a given that the next empreror is gonna be a nero
it is time for a new centre of the world, but i think that is also a doomed project because very likely we are coming to the end of an interglacial and things are gonna get a lot colder soon, and there could well even be a global scale catastrophe that cuts the human population down, right down, with the magnetic field weakening due to a change in galactic field orientation in our vicinity (the 25000 year cycle, every 12000 is Great Flood scale)
i think the most important thing in the next 50 years for our species is keeping our computers working and our archives in one piece because without that it's gonna be hard to thrive if this next cycle is another millennium of cold like the Dryas
