Agree.
This is chilling to hear. Sometimes I really hate the industry I work on. We're really destroying mankind, and it's not in the ways most people predicted. Even Huxley's Brave New World looks optimistic compared to what we're doing.
Smartphones are just the final nail to the coffin. Before smartphones, TV had already killed a of people's sociability (and radio did a lot of damage before TV as well). The book "Bowling Alone" was written well before the era of smartphones.
I was just on a weekend beach trip with friends and, at the end of the day, we considered playing some card games, but frankly we all wanted to just chill on our phones in bed for the last hour of the day, and we chuckled that we would have opted for the card games back in the days without smartphones.
It’s hard for going out and socializing to compete with solitary smartphone time. And it’s easy to avoid ever doing the former, especially once you need it the most.
