On a serious note I definitely think there's a lot of people who misuse communication technology. I've lost count of the number of couples walking along with one (usually the dude) or both tapping away on their phones like the other person isn't even there. Not to mention the endless number of people who won't look me in the face while I'm serving them because they're playing Candy Crush or drivers (and cyclists) who still think it's appropriate to talk or text while using the road. However I think a lot of that is bad human nature and overall and the benefits more than outweigh the costs.
This past week, on my insistence, me & my mum pitched in to buy my gran a new laptop. Among other features it has a decent hi-def webcam in it. I made sure to show her how to use Skype before I left - there's a newly arrived great-grandchild in the US she hasn't been able to see yet but with this tech she'll be able meet her, easily and for no additional cost, for the first time. It's something we take for granted as a pleasant novelty now but that's a specific instance when these tools become invaluable. If dealing with a bunch of grumpy Facebook-obsessed idiots is the trade-off for that, it's a pretty good deal.
