Well as you describe the ideal state it sounds as described by historians of perhaps Ancient Egyptian Dynasties or perhaps Ancient Greece or maybe even smaller society’s such as Irish, Norse or even Indian or Pagan society’s. Whether that was truly as described by historians is another matter.

It will eventually will return to that when this timeline runs its course. Of corse it will start out much more primitive, primitive meaning just not as developed yet, and will get back to the state you describe.

There is no stoping it or changing direction in which society is headed. Some society’s will have less far to fall others, Western, will have further to fall. The way you describe may sound like an ideal state and perhaps for a time it maybe, but there is always a before and after. The question I find interesting is how to pass any knowledge into the future or perhaps that is not possible and that it is just a constant loop through these same cycles.
