I see a problem with modern technology: whenever you like it or not, it will one day disappear.
All modern technology is based on oil, and other fossil fuels. When they run out, we can say goodbye to our modern technology.
Careful planning and consideration could have made it possible for it to last very long, but the present techno-capitalist system is sucking out everything extremely fast to move fat nigger's cars, so much that we can expect a collapse in our lifetimes.
That's technically good news, but when we rebuild afterwards, we won't have much left.
Think about what a lack of oil means: no cars, no plastics, almost no electricity, no heaters, nothing.
We will be set back to the 18th century. Obviously we will still have the knowledge of how to make modern tech, but it will be very difficult practically.
I see only one solution: first, we must achieve ethnoglobe at any costs (Turner Diaries style). Our racial enemies will see no problem in sucking everything dry and dumping the chemical trash in the sea afterwards.
Then, our society will need to change drastically: the globe will be organized in a network of autonomous city-states, and transportation will be handled by trains and other public transportation. Planes and cars will be reserved for military use.
The citizen will be taught how dangerous technology can be, and how finite and precious the earth's resources are. We will prohibit littering, everything that can be recycled will have to be recycled, and wasting will be a major criminal offense. It will also be necessary for every citizen to know how to survive and thrive in the wilderness, to keep a real contact with Nature.
Plastics and other polluting materials be prohibited, and the technological level of the cities will be very low.
But we will still need the best technology possible. This means that the state will possess, use and manage most of the precious resources: technological advancement will still happen, probably even faster than today, but it won't be mass produced and democratized like it is today. There will be a few "tech cities" that hold most of the big industry and laboratories in which everything will take place. Technology will not be used to make the population softer and more degenerate like it is today. The Spartan lifestyle will be the norm.
Even if we do all that, we will only push back a few centuries (even millennia if we do it right) the inevitable. After that I see only two solutions: going back to a tribal lifestyle, or space exploration (which seems unlikely)
