Terminator comes to mind haha.
Also How easy would it be to control a country if every one is hooked up as one massive system.....in theory you could control people, I dont like that Idea.
It is very interesting to think that we are coming this far in science but at the same time (to me any way) I find it disturbing to think of every one patched into the same "mind" , I feel it would make it to easy to control other people. Just my thoughts on every one "downloading" themselves into a computer as was mentioned.
