> On the other hand, I think kids are just staying inside and playing with electronics more too. But why are they doing that? Is the neighborhood not stimulating enough?

Taking for granted this is true for the discussion:

Electronics are way more prevalent, stimulating and social than ever before.

Growing up, my indoor entertainment options were basically reading books, reading comics, watching four channels of often rather snowy TV, or doing other random indoor activities like drawing poorly or playing various physical toys/games depending on age. So things like climbing trees were often more interesting even without usually having other people around--I grew up in the country. (Not that I disliked reading in particular.)
