I personally think much of society has evolved based on some unchanging elements of human nature that are hard-wired in us. Basically, trying to channel our human nature into more positive ways. Ultimately, I think people will find that hard work and community are essential for happiness, and with increased prosperity they will group together into more communal lifestyles centering around things that may not be necessary at that time, but that they enjoy - agriculture, art, etc. Maybe even large groups who completely reject advancements. I think we are already seeing the problems associated with people who are not really connected with anything and that will get much worse before it gets better.
