Baby Steps 
 
In both the 'Matrix' and 'Terminator' movies, one of sci-fi's favorite themes — robots controlling the future — was vividly brought to the big screen.
But we all laughed, of course.  Robots, controlling the future?  Yeah, makes for a great book or movie, but there's simply no way it could ever really happen.  People would simply turn the machines off before they went too far.  The flip of a switch!
No problem.
However, just for the sake of argument, and no matter how wacky it seems, let's pretend that it actually could come about and ask ourselves how.  Obviously, we'd really have to stretch the truth at times, but that's what good sci-fi writing is all about.
For example, I guess we'd have to start with something really wild, like the military inventing some kind of "automated battlefield killer robots" or something, and incorporate them into the military arsenal real slowly so the public doesn't become alarmed.
Yeah, like that would ever happen.
Automated killer robots 'threat to humanity'
Intelligent machines deployed on battlefields around the world -- from mobile grenade launchers to rocket-firing drones -- can already identify and lock onto targets without human help. 
There are more than 4,000 US military robots on the ground in Iraq, as well as unmanned aircraft that have clocked hundreds of thousands of flight hours. 
...
But up to now, a human hand has always been required to push the button or pull the trigger.
...
Military leaders "are quite clear that they want autonomous robots as soon as possible, because they are more cost-effective and give a risk-free war," he said. 
Several countries, led by the United States, have already invested heavily in robot warriors developed for use on the battlefield.
...
Ronald Arkin of Georgia Institute of Technology, who has worked closely with the US military on robotics, agrees that the shift towards autonomy will be gradual. 
Okay, so maybe the idea wasn't that far-fetched.
But we'd still need some kind of nefarious way in which all of these autonomous killer robots could be controlled by some kind of crazy, devious 'mastermind' computer, right?  But that would mean they'd all have to be infected by the same malicious, self-perpetuating, self-learning computer worm whose sole purpose in life is to infect the current computer and move on to the next until every microchip on the planet is infected!
Yeah, like that would ever happen.
Microsoft wants to worm its way into your PC
Microsoft is taking a leaf out of the virus writers' handbook, hoping to use friendly "worms" to distribute software patches surreptitiously.
...
Vojnovic said his worms were capable of learning from past experience.
...
The worm starts by randomly probing for an uninfected host and then targets other computers on the same network. If it fails to find a cluster of uninfected hosts it changes its strategy in order to maximize the number of computers it can patch.
Okay, okay — so maybe the idea wasn't that far-fetched. 
But hold on a sec.  These infected autonomous battlefield killer robots can't somehow magically communicate with each other, right?  They'd still need some kind of huge "new generation" military satellite network to link them all together, like that Skynet system in 'The Terminator', right?
Yeah, like that would ever happen. 
Skynet 5B military chat-sat on the way
The British military communications satellite Skynet 5B launched successfully from Kourou in French Guiana at 2206 GMT last night. The spacecraft will complete the UK armed forces' planned new generation of orbital communications coverage.
If you've ever wondered just how those nightmare 'Terminator' scenarios begin, I'd say a few of the key pieces just fell into place.
