I think that society develops more and more into a digital world. I agree that we need a bit of control, but overall, games and other digital stuff develop peoples's mind.
Imagine a child of 3-4 years old, 50 years ago, compared to a child, same age today.. much smarter, much more aware of the multitude of things in this world. Some may say that education may be the differentiation factor, but i also think the logical is much more complex, and games contribute at this fact.
I've seen parents who denied cell phones, tablets to 10-12 years old.. it's a mistake in my opinion, it's like raising a handicapped child.. they will not integrate very well in the future society.
Supervise your child, control a bit what is he doing, but let him discover the digital world because that is the world he will live in. Thanks for sharing this article!
