Sounds like there's truth there. Researchers said similar things about television, and i think there was truth there as well. In the US and many of the "developed" countries there is increased concern with children who have trouble concentrating in schools. Teachers and psychiatrists call this Attention Deficit Disorder, and treat it with medications.
I remember when I was younger I'd spend hours with books, or drawing. Skill development requires concentration and daily long term engagement, with a piano, car engine, books, painting, ballet practice, etc. I found that a lot of doctors here in Japan had mastered a musical instrument when younger. I think that patience and perseverance- concentration and effort - are learned this way, naturally. This can be a positive outcome of the arts and hobbies...
Two hundred years ago people had to focus on creative projects, built their own homes, sewed their own clothes, carved furniture, went fishing... Now we go shopping.
There's definitely a down-side to modern life.
"As Buddhists, we should aim to develop relationships that are not predominated by grasping and clinging. Our relationships should be characterised by the brahmaviharas of metta (loving kindness), mudita (sympathetic joy), karuna (compassion), and upekkha (equanimity)."
