I will give you some intresting point regarding technology vs Old time.
Technology
In the generation of technology people are more connected from society and less connected to family.I found ,When we are talking to child they don't want to concentrate on one things because they are busy in multiple task such as social media,games etc.They believe in only speaking not in listening.But listening is the biggest power that could be help in achieving your goal.
Old Time
In old time ie 90's people believe in listening and they learn more from their elders in comparison to new generation.
They spend more time with family, friends and relative and believes in cooperating to each other's.They helped to each others even they are also in trouble.
When you have any problem then you should to tell firstly to your parents because when you and your parents will talk to each other then automatically half of problem solve. Many people are depressed day by day because of work load and hactic schedule of workplace.Afterall you should to give more time to your family.We should to give first priority to our loving family.
In whole world the biggest gift forever is -'Family'.
I am even older lol. and I agree that technology has taken away much of what childhood was all about. When I was a kid we didn't have internet. The games we played were on Atari (before XBox) and had very slow graphics. This meant we were bored easily and we played outside with other friends.
Yes, kids are not listening to elders however in "Western" culture that isn't a result of technology. and playing out side with friends all day without adult supervision is no longer acceptable and so it also takes away so much from kids.
You are absolutely Right ,supervision is necessary.
