At the risk of sounding like a conspiracy theorist, this just fits in with every consumer product that's going digital.
They (the government, more than likely) want to have the ability to shut you down & leave you helpless. Cars are now 100% computer controlled: one electromagnetic pulse would disable every single car on the road in an instant.
We all have just about every aspect of our lives handled through our PC's. That can all be wiped out instantly, or shut down to prevent communication.
More & more people are dumping their landline phones for the more convenient cell phones. Like the above, easily shut down or destroyed.
The entire country's financial system is handled electronically.
Now books are going digital .... so when the crap hits the fan, nobody will have any records to fall back on to learn emergency skills needed for their survival.
The ability to remotely shut down your power just fits right into this plan. I think they're up to something. I'm betting that they KNOW that people are going to rise up against them at some point .. sooner rather than later. The more miserable & difficult they can make that campaign, the sooner you will give up & let them dictate your lives.
