And you know what it is even more infuriating, the people that create those apps and those devices do not let their kids interact with them and even send them to schools in which it is forbidden to use a phone at all, this should tell us what we need to know about how dangerous are those devices to underage people, and yet many parents do not take the time to think about this as they are too busy with their jobs to give any kind of meaningful attention to their kids.
Reality in life nowadays, parents are too busy to make money in hope that they can provide a better future for their kids, materially they can fill that up but mentally they are forgetting the important part of growing up, proper guidance is at risk since the technology is really emerging and many factors are influencing the young minds of his generations.
I like your comment about those who created such app, but the chance that they are not letting their own kids to play or to use the apps, not sure about that statement.
It may seem difficult to believe but it is the truth, as we know the center of the development of technologies like that is Silicon Valley, and you may think that in the schools near Silicon valley all kind of technology is used on some of the most exclusive and expensive schools you can find, but you will be mistaken, in many of those schools it is forbidden to use any kind of smartphone or similar technology and instead they use the traditional means of learning, and the majority of those which attend those schools are the kids of those which develop those apps and devices.
