We are the last humans on Earth!
Therefore, it is not surprising that our relationships have changed. We moved from the country to the cities and the process is still continuing as Agri Corporations acquire more land and displace more and more humans to the cities. Today, we no longer live in open farm lands like in former times where the urge was to build empires. Today we are crowded in enormous ant holes of 10 and even 20 million. In the old days men and women were expected to conquer the land, to spread seed like the sands of the desert, to be fruitful and multiply. That mentality is gone. So is the economy that nurtured those relationships and those ways of thinking. We can't have 10 children in an apartment! Much less on such meager wages! The unemployment of today is structural, not cyclical. It was predictable that technology would displace workers to the unemployment lines. Are the unemployed going to have 10 children?
The typical family of the hunter/gathering days was the clan, that of the Age of Agriculture was the patriarchal, that of the Industrial Revolution was the nuclear family and the current one of the Age of Services is the bachelor and single parent. The family type has gone from many members to one. We are becoming solitary animals in a sea of millions. We don't even know the names of our neighbors any more. If Calhoun's Utopian Experiment showed one thing is that before our species disappears, our relationships WILL be broken. No matter what! It is unavoidable. Intelligence is not an antidote to extinction. If it were, an intelligent species would live forever.
Interestingly, the homosexual and asexual mice appear towards the end of the process. The females not only become more aggressive and wean their children early, abandoning them to their fates, but end up not engaging in sex at all. The males lose interest in the females and begin to take care of themselves, to look pretty. These mice spent so much time grooming themselves that Calhoun dubbed them ‘the beautiful ones’.
Humans are no different. Despite our intelligence and technology we cannot avoid the disintegration of our relationships and the imminent extinction of our species. That's what's happening today. That's the big picture.
