Technology has changed the way we communicate, but it hasn't eliminated communication. The supposed dearth of face-to-face interaction can be traced all the way back to dated pursuits like reading newspapers or playing chess. Nothing really changes. We may find more people blundering down the street staring at a phone screen rather than the sidewalk in front of them, but extrapolating carelessness and (yes) rudeness into some sort of societal collapse isn't an original idea, or even a recent one. Anything beneficial is ignored to portray an army of dead-eyed techno-captives ruining the world, one Tweet/Instagram/Facebook update at a time. It's not any truer now than it was back when people stood shoulder-to-shoulder staring intently at the newspaper in front of them.
