What are your opinions??

Computers and satellites are so integrated into our lives, that any disruption to their operation would cripple society as we know it.
Air planes, trains, delivery trucks, and the military all depend on GPS tracking to operate. World wide communication would cease.
The stock market would have to stop trading, banks would freeze assets, ATMs would not work, credit cards would not work, and the only currency you would have available would be the cash in your pocket.
The bright side is, that most of the really critical systems in the world have a redundant structure. If one part of the system fails, there are 10 or 20 other systems that would kick in and take over.
Aside from something catastrophic, like an E.L.E. (http://en.wikipedia.org/wiki/Extinction_event), we don't have anything to worry about.
And if a E.L.E. did occur, technology would be the last thing on most people's mind.
