Yes I agree that the next-gen is addicted to mobile phones and tablets. But the fault lies in the too parenting. The parents should not to let kids or siblings get addicted to devices in very young age.
Things are made to be addictive and attractive in this age. Keeping your siblings away from such an effect is very important for their future. Let them handle such devices only after they attain a specific age, you know, when they mature.
Apart from that, video games can be addictive too. Now there can be many reasons for compulsion for video games, but the best theory I like is that Video Games are made to be won. Say Rohit is a 13 year old boy who plays video games, we will take Call Of Duty MW2, now in real life he is an average kid, but in CoD he is MLG PRO, in school his grades are average but in CoD in every match he pulls up a double digit killstreak, in real life he is not really good at maths or sciences and for this he is punished, in CoD his clanmates hail him as a war hero.
From the above example we can say that Rohit gets:
1.Sense of satisfaction from playing CoD.
2.Sense of Importance from his clansmate.
Now the question comes, should he quit CoD?
Why should he? He is pretty good at it, no one should stop doing what they are good at. He is happy playing CoD and he would not hesitate to play a match or two even if he has to give his finals tomorrow.
On the other hand In Real Life(Short IRL) Rohit is not good at maths or sciences, he is shouted upon and punished. He will have to work hard to get back on track in science or maths plus he might still get abuses for you know trying, I have seen many of my fellow classmates who are weak in maths get punished or abused upon because they really really failed at even trying. They have to do something that makes them happy and in this case, Rohit is sure to play CoD.
For Rohit, CoD is his escape goat from the bad reality he is living in. He plays it because he feels happy, it makes him look badass when he bags in 20 straight kills and dominates the match. His parents won't like because they might not understand why their son plays so much of video game and so they are unable to undermine the root cause.
And very very quickly, Rohit's attention will shift from reality to virtual world of videogames where he lives happily ever after.
And then he becomes an addict.
Oh wait this post is for tablet and mobiles.
Well the above example can be applied to them too.
