Are new technologies positive?

Technologies nowadays are really important for our daily activities. We use them all the time, especially the Internet. But are they really positive?

On the one hand, they are very useful in order to solve doubts and questions that we have. For example, on the Internet we can search some recipes in order to cook something special, or we can hava a look to some photographies of a country that we would like to visit in a future.
Moreover, they help us to disconnect of our worries, and they make us have a good time.

On the other hand, they are a bit dangerous. That's because when we start to use our mobile phone, for example, we first think that we are going to use it for five minutes, but it is never true. We spend a lot of time using technologies in general, maybe more than we should.

From my point of view, I think that technologies are very useful and positive, but we have to take care and use them carefully.
