"AI" stands for artificial intelligence. That implies advanced mental faculties. As such, one would expect AI characters in movies to be among the smarter cast members. Be careful of preconceptions, though, as that's not always the case.
The silver screen has indeed given viewers numerous mechanical characters with AI cores, but that hardly means they're intelligent. It's the complete opposite in many cases. Some of these AI individuals display such stupidity that audiences wonder whether all the lights are on upstairs.
7 "Pops"- Terminator Genisys
In case the stupid title didn't give it away, Genisys is easily the dumbest Terminator flick. That reflects in its cyborg protector. The resident T-800 rescued Sarah Connor as a child and has essentially raised her to adulthood. Sadly, it's failed to grasp any human behavior during that time.
"Pops" is somehow more awkward than previous Terminators. He makes all sorts of silly observations for the sake of stupid punchlines. He also has huge lapses in logic thanks to the sloppy script. For instance, to stop the AI apocalypse, he sends the heroes forward in time to the day before it occurs. After all, who would want a thirty-year head start on preventing Judgment Day? They can pull it off in a few hours. The self-evident stupidity never occurs to Pops; maybe he is obsolete. Schwarzenegger's inability to say the word "cellular" only cements that impression.
6 C-3PO- Star Wars
This mincing robot has been in Star Wars since the beginning, but many fans wish he wasn't. C-3PO is a protocol droid: he speaks countless languages and knows the most minute details of etiquette. It's a shame he has no clue how or when to use them.
Common sense eludes 3PO throughout the saga. He's utterly naive to how people behave or what they want. This often gets him into trouble, which others have to bail him out of. That would be bad enough, but the droid has no interest in learning from his mistakes. Instead, he goes on longwinded lectures about how everyone else is the problem. He never shuts up, so you'll be praying to the Force for someone to shut him down.
5 Dot Matrix- Spaceballs
In all fairness, this flick is a spoof of Star Wars, meaning the droid isn't supposed to be bright. Still, that doesn't stop Dot Matrix from embodying 3PO's worst traits. She has no filter nor street smarts. Instead of a hyper-intelligent machine, she's Princess Vespa's gossiping BFF. As such, she has no shortage of surface-level observations and pedantic comments. Luckily, she's not nearly as annoying.
Much of that comes down to the tone. Once again, it's hard to get mad at this character when she's deliberately played for laughs. The Joan Rivers persona also helps sell the humor better than 3PO ever could. Regardless, it's inconvenient having to lug her around like a suitcase.
4 Data- The Star Trek: TNG Movies
The Star Trek movies with the Next Generation cast exacerbate many of the characters' worst aspects. Most cringeworthy is Data, who was barely tolerable as he was. Now, the Enterprise's resident android has regressed to the mindset of a child.
Fans endure awkward interactions aplenty. He recalls comments made years prior with no context, and he's easily amused by the silliest things. He can't even comprehend basic lines of thinking, making him easy to manipulate. It's as if the past seven seasons never happened.
3 Wall-E- Wall-E
Here's a rare positive example of a dim AI. Wall-E is a trash bot left on Earth after the humans migrated. He's the sole sentient thing around, so his only standard for behavior comes from old films. This naturally makes him clumsy when courting fellow robot Eve.
Poor Wall-E doesn't even understand her mission to find a habitable world. He spends most of the film being whisked along by whirlwind events. He just wants to please his new companion; saving the human population is simply a lucky side effect. True, his bumbling efforts usually do more harm than help, but it's hard to fault him for these mistakes. The little guy doesn't have a selfish gear in his body.
2 The Autobots- The Transformers Series
By contrast, it's easy to wish ill on these hunks of junk. The super-sized Autobots of Michael Bay's Transformers flicks are supposedly waging a war against the sinister Decepticons. Unfortunately, they have little to no initiative, always deferring to the humans. These people are all as dumb as bricks, and that makes the Autobots equally dumb for following them.
Even when taken on their own, these mechanical monstrosities aren't exactly pillars of intelligence. Viewers sit through the empty speeches of Optimus Prime, the topical lingo and unfunny gags of Bumblebee and the others, and the bizarre racial stereotypes that occasionally pop up. Through all this, they get a good idea of the Autobots' mental and emotional depth (or lack thereof). It makes all their bluster about advanced alien civilizations sound like hot air.
1 Guy- Free Guy
Despite appearances, the Guy of Free Guy is actually a revolutionary AI created by a pair of indie game developers. Sadly, he's stuck as an NPC in a Fortniteclone. He says the same things and performs the same tasks day in and day out; he's only there for players to kill during a bank heist mission. Thankfully, he soon wakes up and slowly learns about the real world, discovering his own talents and aspirations. That's not to say it's a smooth journey.
Guy is still the same goof with a positive attitude. He stumbles around his interactions with real people like Millie. The only time his silly grin fades is when he inadvertently beats a tough enemy. Here, he's shocked at his actions and doesn't know his own strength. Like real people, though, Guy learns from his mistakes. His development is like raising a baby. He's clearly trying, and you can respect that.
