Robots Replacing Human Jobs
A lot depends on how we handle things.
As the cost for basics needed simply to live approach zero, our ability to simply provide those basics improve as well. Do that, and people could be more free to pursue more of the tasks that automation cannot replace, reducing their cost as well. Everyone benefits in the long run that way, save those who derive pleasure from having more than everyone else. (Care to guess how much I care on that front?)
Or they could find themselves abandoned, cut off, and starving, until population shrinks to the new labor requirements.
I have to believe that people will refuse to allow the second option.
