You sir, have been watching too many movies.
The reality of this happening ? umm.. maybe, but not in our life time (certainly not mine)
But its good to think about the future brings for out future selves
When Apple starts building FaceTime into a Smart watch would scare me ...
Its would be like MacGyver. Now all we need is a paperclip and elastic band, and we can get out of any situation..
