I think social media is worse for society than tobacco. Tobacco shortens peoples lives, social media is destroying society. We'd ultimately be better living harmoniously but only until seventy than in civil war and mass upheaval.
Lol if you take the number of annual gun deaths in the US each year, you arguably are still in a civil war. 40000+ of your own killed each year just from guns alone. You kill more of yourselves each year than was lost in the entire gulf War of 1990 to 91.
Your way off. Haven't seen ice cream and fast food be responsible for anywhere near as much suicide and detrimental mental health as social media. Folks generally use ice cream to bring you out of that mood not drive it home.
