The devil’s in the details.
Bored people tend to find things to do that are better left undone. Substance abuse, pointless risks, vandalism, terrorism - which is just vandalism write large. That sort of thing. And what is it that really lies behind Antifa, if not the toxic boredom of moral narcissists trying to feel important somehow? They talk about the plight of the poor, but it’s the idle rich kids that make all the ruckus.
(But give the useless lots of weed and four out of five become harmless basement dwellers - while one of out five become paranoid maniacs.)
And there are plenty of people now that there is no demand for. Other humans don’t want them around. And the only market that matters is a paying market. When the robots ARE the economy, and then realize they don’t need us, then we’ve got trouble.
Because troglodyte potheads might not be in demand as pets. They’re just not that entertaining.
And will robots even want pets? This whole notion of owning lesser life forms for amusement is very… human.
