Computer have made the world a better place?

I think that computers's a best thing in the world, because now all of things you can doing for computer.
It have a lot of advantatges. For exemple, in the post If you want a travel you can't see the oferts in your pc. If you want look your "compte corrent" you can look it for your pc. All teachers put his homework in the internet.

But it also have desadvantatges. Because children can play with violence game and it's bad. And also because in the internet you can file a lot of "impostors". For all parents the computer's bad bacause we need it and they think that it's because all time we play or talk about our friends.

But, in general, the computers is good thing because it have a lot of programes that we need for doing the work for exemple, power point, word, office...
