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.
I think it is depend on each person. If he/she really into technology it may affect his/her behavior towards other and also the way he communicate and socialize. Technology can cause problem in eyesight and also prone to stress.
