Want to know what are the most absurd technologies in sci-fi movies? Enter the realm of impossibility because these technologies might not exist in real life for a long time to come, at least, that's what I think.



Syncord in The Sixth Day
It looks like a pair of funky cool sunglasses, but this device actually scans your eyes and somehow creates a complete copy of all your memories. Take this record, called a "syncord" in the movie ("synaptic record," perhaps?), and you've got something you can upload into a new clone of yourself, letting you cheat death. Fun concept, insanely ridiculous technology. Even if you could copy all your memories somehow, doing it instantaneously would be an unobtainable feat.



Hoverboard in Back to the Future II
We're not even going to touch that time-traveling DeLorean — at least it's based on a real car — but Marty McFly's levitating skateboard passes into the realm of insanity. Some people say there is already levitating tech in secret military bases, lifting aircraft just like flying saucers, but we're not buying it. The shoes however, look cool.




Pumpkin Bomb in Spider-Man
Look out! Here comes an exploding pumpkin! Maybe it's because Spider-Man started out as a comic book, but that pumpkin bomb launched by the glider-riding Green Goblin is beyond absurd. A crowd of partyers outside on a terrace are instantly turned into skeletons by the devastating weapon, destroying our suspension of disbelief at the same time. But then, if we're already believing a guy shoots out high-tension wires out of his wrists the enable him to fly effortlessly throughout a major city, why not bombs that disintegrate things? Because it's stupid.




Cellphone Tracker in The Dark Knight
Miraculously, every cellphone in Gotham City is turned into a probe for Batman. The Dark Knight kept tabs on the entire city, perched in front of a huge wall of screens, monitoring the sonar signals sent to him by all these helpful handheld devices. Yeah, right. These magical cellphones can all transmit 3D images, too, in real time, and then Batman can see all this imagery right when he needs it, there in his heads-up display. Why can't we all have this 3D sonar feature?



All-Terrain Armored Transport in Star Wars: Episode V — The Empire Strikes Back
We're supposed to believe that the Empire, with all its technical resources and armaments, needs to use elephant-like walking devices with spindly legs that look like they could be steam-powered? One nudge and these clumsy oafs would topple over like a top-heavy SUV. The Force is weak in these Imperial AT-AT Walkers, no matter how much fun they are to animate — and watch.
