Today technology is very important in our life because it´s used for almost everything. But as everything it has good and bad things.
In my opinion, depends that what do we use it for; technology can be dangerous or useful.
Actually, the web is one of the most dangerous places. Also, as an addiction, it has many consequences on our health, like obesity (due in a sedentary lifestyle), attention span, insomnia,etc.
In my life, I think that technology is a useful tool, because I can be communicated. And it´s very important in my education, I can access books I can´t buy. In conclusion, it makes my life easier.
