The world has changed with improving technologies over the last half a century, which affected to modern kids. It caused some problems like big abyss between siblings, especially children, and vulnerable relationships in family and society.
The main problem is that technology can affect to a child both positively and negatively, but the last one more common and creates an imbalance. Nowadays, vast majority of children waste their time to watching TV series, playing games, useless chattings, and so on. If a kid has a phone,or a something like this, he will easily distracted by it. However, there are some kids, especially teenagers(but even so, most of teenagers live a purposeless life) who know rational use with access to the technology. They are usually smart, strong and more experienced, which causes very big abyss between them and others. It promotes dividing into social groups which very often represents into conflicts. We can see that in schools where always fittests have been winning, but currently it is even more complicated.
The other considerable problem is that relationships is getting access to the less and less amount of time in children's lives.
Relationship generally needs contribution in the form of time. As was mentioned before, displays and monitors have almost all of kids' attention. As a consequence we have more asocial children than in the past, who can't communicate normally even with the own family. A lot of researches show that asocial children grow into murderers, psychopaths etc. Furthermore, childrens like these usually physically weak , which makes them susceptible to diseases. Finally, this will affect to the next generation, which will more get sick and fear the society.
In conclusion, children have became addicted to virtual life which steals away their personal life and good relationships. They are becoming more unadapted and it causes more problems with health and psyche. To avoid more complicated consequences we must give children our attention, our love and more choices.
