I definitely think there's a silver lining (at least here in Russia). My theory is that smartphones reduce street crime and bullying by providing stimulation.
Back in the eighties when I grew up, the world was much, much less stimulating than it is now. Bullies bullied weaker people, hit on girls and tortured animals just to get their dopamine fixes and to alleviate boredom.
Now all the potential bullies have smartphones full of apps. And the homescreen apps they have on their phones are the result of a decade of competitive evolution -- they are apex attention predators. As a result, their smartphones provide them with more than enough stimulation to keep them occupied all day: porn, dating, gossip, news, games, gambling.
As a result, I haven't been mugged in a decade (knock wood). There were a couple of tries, but I just disregarded them.
I say this is good.
