Internet is simply a reflection of the world we live in and a person can find both good and bad on it, depending on what they are looking for.
If a child is drawn to negative influences, it will find it on the Internet or elsewhere. It’s a difficult job for the parents to raise their child in such a way that it learns to seek out and feel good around positive people and positive influences.
In my experience, my career and even my hobby, the Internet has been invaluable. The resources I have found have made my job so much easier, I cannot even calculate it. Also, I use it increasingly for shopping. There are some specialty items I would have no way of getting, if it weren’t for the Internet. Some of those items are very important to my health.
It’s really unfortunate that the Internet is also so full of hackers and spammers. But again, these are negative influences which would have found some other outlet, if we didn’t have the Internet. They are simply reflecting a part of our species which is bent on being destructive.
