Wearable tech brings with it the issue of how to attach all of it to your body. I recall more than one amateur radio operator walking around with a vest on and oodles of cords and radios dripping from his body.
Take that image and update it to this century and you have the SCOTTEVESTthat is made to house all the digital tools you want and connect the wires with bonus "on board" power to boot. I can see a few emergency managers in the future "getting wired" for this type of set up.
Saying someone is "wired" might have a whole new meaning very soon.
