A dire prediction, indeed. How did the Security firm Internet Identity’s president and CTO Rod Rasmussen come to it?
He came to it by virtue of the devices we have which communicate with themselves and with other devices by blue tooth and via the internet. Rasmussen pointed to remotely programmable pacemakers and vehicles. These could be hijacked.
Actually, his “idea” is hardly new. It was in an episode of “Homeland”, last season.
Also, security breaches in the computer controlled infrastructure (gas, water, electricity, traffic lights, etc.) aren’t hard at all to imagine. Stuxnet did it, and that malware (and subsequent generations of it) are “out there” already. Is it really hard to imagine drones (which will become increasingly popular and available) being hijacked and used for nefarious purposes?
Your Cisco 7900 VoIP phone can be used to spy on you (link) as can your networked printer, etc. Serious? Well, President Obama has one on his desk. The more devices, the easier it gets. Information theft is (now) more the way that crime is going, but lethality is a possibility which should not be forgotten in the age of cyber terror.
Will this happen? I don’t know (just thought of ZubaZ typing code... 
).
I do know that man has never passed up the opportunity to use technology for evil.
