I wrote a story of love post supermortility, the coming age where death by aging is no longer mandatory but is a choice. I've also written on how interactions between people will change as apparent "age" is decoupled from temporal age, what I've dubbed the coming age of oscillating senescence. When a 200 year old looks no older than a 28 year old different cognitive dynamics of interaction are possible between people of vastly different levels of wisdom and these will effect society in unknown but I think ultimately interesting ways.
Another reality under the age of SHI will come as Love, often claimed to be lasting "until death do us part" actually escapes the boundary of mortal death events the true value of the emotional connection defined by the word will changed. I wrote about this in my post Loves New Meaning.
A further reality though in such a world where the SHI provides all our needs and goes further to satisfy the bulk of our wants it is interesting to think about how present distinctions of class, defined mostly around access to liquid capital that facilitate those differences will change radically.
Some aspects of class will remain but the relative percentages will shift, the poor classes will simply disappear as the SHI will provide basic and beyond basic needs to arbitrary desire for almost all. A portion of "poor" still will exist however as some will chose to eschew the blessings of the SHI fabric in lieu of living "naturally" such individuals exist in society today and there is no reason to think that this philosophy will be made obsolete once SHI is in place.
Another class are the people who by virtue of mental illness inhabit the poor class state, these people will find them in the state by virtue of their pathology.
Toward the middle of the class pie the low to upper middle classes will normalize to a common affluence as people satisfy their personal needs and wants via the optimal production of the SHI, this "class" will mostly consume the poor as mentioned previously save for the mentioned exceptions on the high end a similar persistence may likely exist.
The desire for human beings to socially challenge one another for position in relationships or politics will continue to find a sector of the affluent unsatisfied with just having the ability to be at parity with others. The desire to be perceived as "better" for the reasons mentioned will still assert and in a way drive the seeking of more distinction markers of a separate class.
As the vast middle consumes the bottom and top into a consensus of affluence across society the mixing of social, ethnic and religious DNA between what were formerly distinct classes will be *accelerated* to yet unseen levels. These effects will be very good toward the mollification of xenophobia and radical entrenchment that threatens our very survival to this day. This thus presents itself another critically important consequence of the formation of the Self Healing Infrastructure.
