It will be electronic. A guy walked up to me today and said "Hey, you're that guy who..." and then he gets this real blank look on his face, proceeds to pull his phone out of his pocket, pull up facebook and walks away. -_- :zombiefalldown::zombiefalldown::zombiefalldown::zombiefalldown::zombiefalldown::zombiefalldown::zombiefalldown::zombiefalldown: It has already begun.
If you ever want to perform a terrorist action on America...just come up with a way to shutdown all cellphone towers. Even if you didn't affect a single other thing I'm convinced most of the population under 40 would be curled up under their bed in the fetal position.
There was a Ray Bradbury Theater episode in the 80s that postulated a future world where every single person would have a personal communications device, and they'd be talking on it 24/7. The main character got sick of watching everybody being self-absorbed and ignoring each other in person, and started destroying peoples' phones. He was arrested for murder! I saw the ep a few months ago on DVD. It was scary it was so spot-on.
