@quinn yes, I'm with you. Smartphones have not created behaviours, desires, fears or conflicts that haven't existed before. They haven't changed the core drivers and expressions of human nature. They're not the cause.
OTOH, I remember as a teen being really glad I got to go home at the end of the day, away from those bitches who tormented me. Now kids carry their bullies home in their pockets. Now their terrible decisions get memorialised and shared. Phones make some bad things worse.
