You are both right, some teenagers are behaving irresponsible with learning new things and there are some who have learn things that I never had the chance to learn at their age but these teens easily go bad.
You put them on the right part of technology, after learning and thriving into a almost pro personnel they will leave the good route and venture into crime world of the Internet, talking from the little experience I have seen here, even the kids that have good parents still went bad.
It seems we are reaping what we sow in terms of kids this days, everything seem too rushed, today education are rushed on them, and we will all say that they have sharper brain than us, that's why you will see a 15years old kid trying to make life changing money.
When I was this age I don't even have the time to think about money, today parents are worse as some of them are even expecting their sons of 15 to start earning money home.
You've raised very fundamental issues with your response. Two things or let's say three factors are the root cause of this bad behavior and habits shown by teenagers today. The first is bad parenting. The second is peer group influence while the last one is the overexposure of these teenages to several viral videos and contents on the internet especially on social media platforms.
Bad parenting has led plenty children into unethical dealings and bad behavior because of the poor mindset imparted on the kids. Bad parenting has led many kids into unnecessary family pressure, lack of love and discipline as well as over conservativeness. These amongst many of other reasons are why teenagers learn bad things easily without having any accountability check whatsoever.
Peer pressure is the second factor that has seriously influenced the character of teenagers, including those who came from decent family background. Imagine a teenager engaging in uncouth activities without the knowledge of the parents through the influence of their friends. Due to the youthful exuberance that's mostly exercised by teenagers alike, many copy bad characters and engage in unethical activities from their childhood friends or peers within the school community.
The last influence is almost like a silent killer, it infest the lives of teenagers even under thorough good parental care and discipline. It is almost the devil people don't know that has really turned the lives of many saints to otherwise as a result of the overexposure to illicit and unethical contents online without them even noticing the adverse effects it comes with. Sometimes makes you feel almost impossible to identify the cause and remedy the solutions.
