Speaking to point 2, I think it's likely that with a large number of people no longer feeling work stressors, we will gravitate towards meatspace small communities not substantially different from tribal communities or villages.
Those models of living were both very successful during periods of human existence when there were fewer hours devoted to labor.
The outputs from those communities will mostly just be self existence and social cohesion.
There will probably be a renewed interest in philosophy, theology, math, chess or other stimulating intellectual pursuits that have no direct economic stimulation. I think it will actually be a fantastic time to be an academic.
Many humans are very good at avoiding boredom through intellectual or artistic pursuit and for the rest there is neighborhood gossip and/or skydiving.
