Greetings from a more ancient dinosaur. I remember when houses had only one phone, in a central hallway, and we had to pick up our letters at the Post Office. And long distance phone calls were cheaper at night.
But I'm laughing. This question reminds me of a newspaper cartoon of a wedding where bride, groom, minister, and members of the congregation are texting one another throughout the ceremony even though they're all in the same room!
Technology can get in the way of person-to-person contact only if we let it. We're not taken hostage by our computers. They don't own us (do they??). We are in charge of them.
I like computers. I generally like e-mailing better than telephoning (because I can contact a person at midnight without being disturbing). I like FB because I can wave at people whom I unhappily never see any more. I also like anonymity sometimes (e.g., Mamapedia). If you knew me, you probably wouldn't care what I think about this question! I also can Skype with my family members who live across country, and when my son is sent away (with the Army) his family actually get to see him. That's wonderful.
But it's definitely not a replacement for real people. I love being right with my family. I like to meet with friends. I love talking to neighbors. I like to get together with my relatives. Why not do it? I can FB my neighbor across the street at 10 p.m., but I actually TALK with her during the day.
I don't text. People who will communicate only by text will accommodate me or not communicate! Conversely, I will phone people who prefer being phoned. I will even write snail-mail letters. Communication methods have expanded, not contracted; it's too important a thing to say, "My way or not at all."
