I think it is possible for a person to change personality when he/she gets too attached on technology?
I'm a gamer and I prefer violent gore games when playing on my computer, I think that affected that way I speak and treat others in a more aggressive way and IT's really not a nice change.
Too much usage of technology and devices can be bad for our health. Some teenagers get less sleep because of computer and cell phone addiction. This will deteriorate your health slowly until you get sick.
