Why are kids content to sit inside 24/7 these days?

When I was 7,8 years old, all I wanted to do was go outside, play football with kids on the street, get a pickup game of basketball going, ride my bike, go for walks in the woods, just explore the outdoors and have fun. I've always had access to video games and a phone, but they do not seem as fun to me. Man, times have changed.
