Well advancement is actually not on the teenagers but at a global level as whole because the world itself is the one that have actually advanced to the stage that it's even possible for a child to not be or go to school and still get the basic and proper knowledge of things that he would have been taught there because technology has advanced so greatly but the thing about good inventions also is that there is always an equal opposite side as same as the positive.
But the problem is that the initiative to learn in children or adolescents is lacking so it will be very difficult if not guided properly, yes we know that any knowledge we can get easily in this fast internet era but the problem is how they use the internet itself.
Teenagers are more susceptible to anything that is enjoyable such as gambling and because of that they are also very worried about getting into gambling because having a bad gambler mentality before they can mature will be very difficult for him in adulthood, and that is what is very worried about a teenager or child who already understands internet technology, they don't read the bad effects and good effects usually and they only access what makes them happy they will do it happily, besides gambling also another example is playing video games is also included in one that must be worried about today's teenagers apart from gambling.
Playing video games is probably the biggest for parents today since as early as 8 years old, kids are already playing games like the Roblox and if they discover more games where they could wager money it will be another game to get addicted to. As they grow older the bolder they could become in wagering how much they have.
Maybe choosing which school for your kids will help your kid's development and will not stray to gambling because they learn it from the teens inside the campus. There were schools prohibiting kids from using phones on their campus AFAIK.
