New technologies, good or bad?

It's a fact that new technologies have caused a great impact and new improvements have been made since last century, mostly in the last 40 years or so but, are they good or bad? Would they help to improve our days or they will turn into something negative? Well, I read an article back in August which said that most teenagers are only focus on their smartphones and that make them avoid real contact with people. That said, I don´t truly think that generalizing would cause any good. There's plenty of people that doesn't feel that dependence.I think It's just a matter of organizing time, moreover if we're dealing with children. But irrespective of this, technologies have improve life of disable people and that's, for me, the most important thing.
