I think it’s just an indication of how much more addicting technology is than people care to admit. To say that there was nothing fun to do back in the olden days would be false. These days there are way more options that are much more addicting and gratifying. Why play in the park when you can blast people online. Games are designed to build addiction and sure enough it works - kids would rather fame than do anythin…
I think people are saying the opposite. When I think back at all the most fun things I did as a kid, a large chunk of them are totally unavailable to most kids now.
What is there for a kid to do outside now? Most of them could go outside and walk for hours in any direction and not find anything but rows of houses and roads. Likely all of their friends live so far away that walking there isn't an option.
Why play in the park when there may be no park you can get to without your parents driving you there and when you get there you find no one your age or that you know.
