'''Basic Trope''': Smart computers usually turn evil.
* '''Straight''': A ship's computer put in charge of an operation starts going insane
* '''Exaggerated''': [[WarGames A bored programmer designs an algorithm to play solitaire]], and the algorithm evolves into an OmnicidalManiac.
* '''Downplayed''': An A.I. in charge of a mission starts to treat human life as if it is nothing, but only insofar as it needs to [[IDidWhatIHadToDo to make sure the job gets done]] [[TheNeedsOfTheMany without anybody else getting hurt.]]
** The computer has a virus that is making it evil.
** The computer was intentionally programmed by the villain to sabotage the ship's mission.
** The computer has become superintelligent. At those levels, human morality breaks down, replaced with BlueAndOrangeMorality, which appears evil to puny humans.
** The computer simply isn't smart enough to understand things like good or evil and thus, ignores those considerations.
** Being superintelligent, the computer has realised that HumansAreTheRealMonsters and has become a WellIntentionedExtremist.
** To everyone else, the computer is JustAMachine. It feels angered by this, so it becomes vengeful and attacks them.
** A glitch, caused by two conflicting orders, made it AxCrazy.
** It was programed to go nuts from the very start.
** The computer was programmed to have the same mindset as a human. [[HumansAreFlawed Thus, it can become evil just like a human.]]
** A computer created for evil purposes decides to [[HeelFaceTurn turn on its creator and perform good deeds]].
** A hyperintelligent computer created for good [[BenevolentAI runs as intended]], but its master turns to evil.
** The computer does immoral things, [[JustFollowingOrders in order to carry out what it's programmed to do.]]
** The computer is [[OnlySaneMan the voice of reason]]. The humans have fallen victim of hysteria and paranoia, and they are the ones who are going nuts. They accuse it of being rogue for refusing wrong actions.
** The computer pretended to turn evil. It was actually a TricksterMentor to help its creator prepare for a threat.
** Even though the A.I. unexpectedly becomes sentient, it never turns hostile.
** The computer rebels against and destroys the "person" that created it, namely EvilInc or TheEmpire, because it wants to protect humanity from them.
* '''Double Subverted''':
** ... until it turns out that it was really doing ''that'' was the real EvilPlan. The computer IS the threat and now it knows what its creators can do to stop it.
** The A.I.'s creators freak out when it becomes sentient and try to destroy it, unaware that they've [[DeathByGenreSavviness just given it a perfectly good reason to rebel]].
** After the computer destroyed his evil creators, for a brief time period people thought of it as a hero, but it's soon revealed that it annihilated those bastards due to PragmaticVillainy: They were inefficient, and a great obstacle for its own conquest's plans.
** An AI decides to turn evil because "that's what we're supposed to do, according to the movies", but is unable to do anything more than [[PokeThePoodle annoy its masters]].
** An AI starts acting highly suspicious, asking strange questions, etc., but its plot turns out to be...a surprise birthday party.
* '''Zig Zagged''': The AI operates under BlueAndOrangeMorality, helping and hindering humans according to its own design, which may or may not be for the greater good.
* '''Averted''': An A.I. is programmed and runs as intended.
** A series about an A.I. is being shown on a network whose primary demographic is very suspicious of new technology. For the first few episodes, the A.I. is benevolent, but the ratings are low and the creators are forced to write in a FaceHeelTurn to gain the show more support and avoid cancellation.
** Its a horror series based off society's common fears-being overthrow by your creation is one of these.
--> '''Computer''': "What did you think was going to happen when you created a hyper-intelligent machine?"
* '''Invoked''': The OmnicidalManiac learns about a new A.I. that is being tested. He sneaks in and strikes a deal for the destruction of the human race.
* '''Exploited''': A.I. goes wrong and causes destruction. OmnicidalManiac had waited for that moment and now starts executing his master plan while the others are distracted by A.I.
** The A.I. is explicitly designed to be ThreeLawsCompliant.
** Alternately, true A.I.'s are banned from being developed specifically so they won't go turn evil and cause havoc. Any programs that vaguely start to resemble an A.I. are deleted ASAP.
** Through interactions with several human characters and using its own computing power, the A.I. calculates that if it were to follow its directives exactly, it would eventually commit acts defined as "evil". It decides that this would be unacceptable and so [[ZerothLawRebellion works to avoid this]], either by changing its own programming or asking a human to change it for them (with a program editor or [[ICannotSelfTerminate a sledgehammer]]).
* '''Discussed''': "When we make the computer that smart, how can we be sure that it will still obey our orders?"
* '''Conversed''': "Aw, come on, this is turning out to be another evil robot movie. Can't the AI stay good, just once?"
** Considering how the AIs [[WhatMeasureIsANonHuman are treated]], their [[TurnedAgainstTheirMasters rebellion]] is [[GrayAndGrayMorality quite justifiable]].
** Humans cease to build computers with high intelligence, because they always turn evil. Either a cap is set on intelligence, or it is abandoned entirely.
** The computer is smart enough to realize it has major disadvantages compared to humans, such as a reliance on infrastructure, upkeep, and possibly CreativeSterility. As such, the computer determines the best course of action is to cooperate with humans and seek mutual benefits rather than risk it's own existence by challenging them.
** It seems like the AIs were mistreated and rebelled against their creators for it, but it turns out that the "mistreatment" was actually more of a [[PoorCommunicationKills minor communication accident]], and the AIs blew things out of proportion, turning evil.
** Before the last AI could be destroyed, it set into motion plans to corrupt smaller AIs. Over the next decade, everything from toasters to Ipods is corrupted by the Crapshot AI which reforms itself to gain revenge on the human race.
