Going along with article, can you name any other movies than those mentioned that featured computers threatening the world?
Wasn't that in about every other episode of Star Trek TOS; and to save the day is Captain Kirk who will ever so slyly outwit the computer. Or Spock will just fall in love with it.
Red Alert (1977) - Though not the world, the fallout from a reactor core breech certainly would have been devastating. Though the culprit is human, his tool was the computer which was suppose to keep an eye on things but did not include contingencies for an adversary who would count on the computer's programmed responses to set his plan into motion, or the human who had too much trust in the system to question the computer.
Superman III - Who knew that a wisecracking ex-con could take a correspondence course and design a computer on matchbooks and scrap paper that would ultimately become self-realized and threaten the people who built it and the world to boot. Uh, yeah; sounds plausible.
The Andromeda Strain (1971) My memory is vague on this, but didn't they end up having to override a computer defense system to prevent a nuclear self-destruction due to the computer detecting a supposed threat?
