Jan 21 2011 11:56 PM Hyuuga, I am paying attention to it. I work closely with critical infastructure and network security specialists on a weekly basis. Online portals for paying your bills have no control or connection to the actual systems - interally within these companies, there is either a complete physical separation or logical separation with authentication procedures to actually pass the request for service/cancellation to actually happen. There is not a single system on the other end of the line that "rules them all" within even a single company - they are separated by either human input or computer security. The encryption levels commonly used requires more computing power than currently exists in the world to break in real-time - and as more computing power becomes available, higher-level encryption is used.
Having "one key" to control these things within a single company, let alone multiple companies, would be considered almost criminal negligence by the company involved, severe ignorance by the network security personnel within the company, and a high risk behavior by any sort of risk assessment. It would take millions of people with the IQ of retards running every major company in the world for such a stupid decision to be made. Even then, a sociopathic CEO would block it because it isn't even a financially smart move because the risk is too high!
Now, say a company comes along and decides to create a unified experience and tie all this stuff together. Guess what: its a glorified liason service, nothing more. These companies would not allow another company priveledged access to their systems...they could send REQUESTS to those companies on your behalf, but that doesn't gain control of their system. If a company was big enough to become what amounts to the global conglomerate and have everything under one umbrella, politics would even get in the way! That kind of monopoly is not permitted in many countries.This doesn't even get into the required computing power to even run a malicious AI of the level shown in this movie, let alone the major advancements in AI development necessary to even sniff at it.
I could write pages upon pages upon pages of hurdles that you have no idea even exist. Your mentioning of DVRs (glorified recording service, not two-way communication), and the military (the military mantains physical separation only linked by human interaction between critical systems and outward-facing internet-capable systems) signifies that you are severely misinformed on the topic. You should not say things people will read and interpret as truth if you yourself do not understand the topic at hand.
