Not so surprising, but I'm not so sure it's a re-wiring of the brain. Like any skill, if you don't practice face-to-face interaction your abilities will not improve and any existing skills you have will likely atrophy. I, myself, long for a future with no human interaction, but it would probably be tough to continue my teaching career;)
John K. Mullen reporting …Digital Natives Are Slow to Pick Up Nonverbal Cues:
If you're a digital native, you should be aware that the internet may have partially rewired your brain in such a way that when you meet people face to face, you're less capable of figuring out what they're thinking.
No, I'm not joking. There's a significant amount of scientific literature on this. Compared with people who didn't grow up using computers and the internet, you may be slower to pick up on nonverbal cues such as facial expressions, tones of voice, and body language.
