If there's one thing science fiction teaches us, it's that highly intelligent computers are a bad idea. Here's the kind of thing they get up to – scientists, we hope you're paying attention.
Hal 9000 from 2001: A Space Odyssey
Supposedly hyper-intelligent ship's computer
• Goes mad.
• Kills a bunch of people.
• Sings Daisy Daisy really badly.
• Generally acts in a way that puts your laptop crashing while saving a Word doc into perspective.
The computer from Superman 3
Grand Canyon-based supercomputer designed by genius Richard Pryor on the back of a napkin
• Nearly kills Superman with a beam of Kryptonite.
• Becomes self-aware.
• Richard Pryor tries to kill it with an axe.
• Learns to turn people into zombie-cyborg killing machines (see pic).
• Genuinely terrifying.
Joshua from War Games
Eerie childlike US military supercomputer
• Not smart enough to prevent itself getting hacked by Michael Broderick.
• Nevertheless manages massive nuclear arsenal.
• Obsessed with tic-tac-toe.
• Nearly wipes out humanity in a 'game' of thermonuclear war.
NB: Supercomputers LOVE nuclear weapons.
The Matrix from the Matrix
Manifestation of evil machine intelligence
• Enslaves humanity.
• Uses humans as some kind of weird bald fleshy batteries.
• (For some reason.)
• Possibly just has a thing about shaving people and covering them in goo.
Deep Thought from Hitchhikers Guide to the Galaxy
City-sized thinking machine
• Asked to find the answer to life, the universe and everything.
• Spends millennia on the problem.
• Comes up with the entirely useless answer of 42.
• Admittedly, doesn't kill anyone.
• Still, what a time-waster.
Skynet from the Terminator films
Global digital defence network
• Wipes out most of the world with nuclear weapons (those again).
• Tries to finish the job with Austrian-accented, time-travelling cyborgs.
• A total dick, basically.
Conclusion
Supercomputers are creepy monsters intent on destroying or enslaving humanity (and possibly covering them in goo.)
Is this what you want, scientists? Is it?
