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.
It would be different for alot of people, but me personally i play alot of violent video games and it makes for a great vent for my aggression. I also do associate the even shorter attention span of kids to social media. We are very much used to very short condensed forms of information that anything longer than 5 minutes will eventually be ignored.
