bet a lot of it has to do with the internet.
Games for individual players, hours alone, and social interaction through a screen and a keyboard. People are more blunt in casually calling others idiots, and dating rejections take only seconds of interaction.
Feck yeah that’s lonely. GO OUTSIDE and play with a dog.
My youngest has Asbergers.
He tried for years to make friends. No one wanted to hang with the weird kid.
Ironically, he flourish on-line. Had a successful youtube channel, set up servers, gathered friends from across the country. He even has a lovely, very pretty girlfriend (she lives an hour away and they see each other on weekends) and is talking marriage.
It’s a different world and he used technology to his advantage.
But you are correct; there are too many people who live on the computer.
