About this whole AI taking over the world stuff, while nobody can be certain, it's highly unlikely. EVEN if we were to allow some super computer android deal to made, if it were really that intelligent, why would it have a reason to kill unless we put it there. People always are negative about this. Why can't the AI turn out to be like Data from Star Trek the Next Generation? If it's programmed to be like a human, it would just be a REALLY superior human. And if a computer ever decided to attack, we'd just shut it down. Ya know, just install windows on all androids, and when they go to take over the world their system resources would fall the crap and they'd send out error messages
More or less, my point is even if computers were to rise up as sentient beings, they wouldn't have a reason to kill. They would be more inclined, it would seem, to HELP those who gave it life. Why can't the android be Data or that dude from Millenium Man? Why does it always have to be evil?
p.s.
In the Matrix, the AI aren't all that evil. We got scared, nuked the shit out of ourselves, and they tried to save us. Granted, they eat us, but hey, ya give alittle ya get alittle. If the AI were really evil in the Matrix, they wouldn't have gone through all the trouble to make our lifes seem good. They put us in the peak of our civilization. Pretty nice if you ask me
