Negative Things about Technology

Technological advances in general are a great thing. Most of them have improved our lives, making things easier for us. For example, I think that smartphones are a great thing and they have improved our lives, allowing us to communicate with our friends and family in a more efficient way than we are used to.
However, I sometimes would like to live in a world without smartphones. There are a lot of people who spend a lot of time checking their mobile phones everyday, people who are very dependent on their smartphones. Let me give two examples of how this can affect our daily lives in a negative manner: I have seen a lot of people having a coffee with their friends in a bar at a coffeeshop who pay way more attention to their mobiles phones than to their friends. Moreover, I have seen people attending to a concert or to a party who were totally focused on taking photos of the event instead of trying to have fun and enjoy the experience with their friends.
I find this kind of sad. I think that a lot of people should practise a bit of moderation in this matter. What do you think about it?

Excellent job, Santi! Mostly just a few small spelling and punctuation changes.

I also changed bar to coffeeshop. In Spain you can go to a "bar" at any time of the day to drink coffee, soda or whatever you want, but in the United States a bar is a place where you go at night to drink alcohol.

I agree with you. I think people are forgetting how to live in the moment because they always have their face stuck in their smartphones! It is sad.
