I believe cell phone have impacted the relationships people have with each other. People no longer have to hone their social skills in person because they get most of their human interaction through text. I believe this is particularly troublesome when it comes to job interviews as an individuals face to face interaction won't be as good as they were maybe 15 years ago. Phones make it easier to schedule and set up events, but once the people show up to the event they tend not to talk to anyone they didn't come with or know. You can't truly sense emotion through a cell phone, and people will often avoid try to avoid awkward situations and just talk over the phone, making it more difficult to read people. So cell phones make people more awkward, less emotionally sensitive, and antisocial.
