I hope for the future that the world will be so pacified by then that there will be no more such wars as before. Until then, it should be a matter of course in the "developing countries" that people can adjust peacefully to coexistence and design their lives with the right technology in such a way that everyone receives a reasonable standard of living, i.e. the right educational opportunities, sufficient food, etc.
These countries manage their raw materials themselves and are reliable trading partners for the "industrial countries".
The technology is so advanced that solar power can be stored in sufficient quantities, so that "Dunkelflauten" can also be overcome over several days and in winter.
Especially in the desert areas, the solar power harvest will be so good that all people on earth will have their livelihoods, so that it would not be necessary to invade other peoples in armed conflicts.
