Fictional technology is fascinating in the sense that on one hand, it's pure wish fulfillment -- the writers can create the most awesome devices imaginable and don't have to worry about technical limitations or feasibility. But on the other hand, so much of it is almost laughably flawed. Take movie robots, for instance. They can think and love and perform amazing feats, and every kid wants one. Yet if they were built and sold by a real company, they'd be yanked from the market within minutes due to their glaring design oversights. For instance ...
5The T-X in Terminator 3 Is a Serious Downgrade from the T-1000
The T-1000 in Terminator 2 truly has no weak point (in fact, we're not sure where its crucial circuitry even could be, let alone where it might be). This is because it tap dances between solid and liquid form at will, meaning that physical damage is something it hands out like Darfur fliers at a coffee shop but can never actually experience. The only reason Schwarzenegger is able to destroy it is because someone built a pit of lava next to the Los Angeles freeway, a scenario Skynet probably read through streaming tears of hilarity before dismissing it from the T-1000's contingency programming.
So in Terminator 3, the evil robot must be even more hardcore terror-awesome than the T-1000, right? They wouldn't bother to waste our time with a sequel 12 years later without coming up with a cyborg so tit-shatteringly badass that the T-1000 would hang posters of it on its wall, right?
"I'm here to kill John C- why are you laughing?"
What we got instead was the T-X, a machine utterly inferior to the T-1000 in every conceivable way. Both could change their appearance and deliver menacingly deadpan compliments about peoples' vehicles, but while the T-1000 could shape shift into literally anything it touched of equal mass (even a goddamned patch of floor), the T-X was strictly limited to different variations of the same hot woman. There's even a scene where it inflates its human female breasts to more effectively coerce someone, and while we agree that this can be a useful ability, it maybe isn't as universally effective as being able to dopplegang virtually any person on the planet.
But that's not even the most severe design regression. The T-X, like Schwarzenegger's moldy old T-800, has a physical endoskeleton. If Skynet can make a time traveling assassination machine out of liquid metal, why would it ever build one out of anything else? The T-1000 could not be harmed by anything -- it shrugs off bullets, grenades and explosions without a scratch. Arnold takes the same abuse, but comes out looking like he got raped by a Tyrannosaurus, because he has a permanent solid-state structure. So why would a sentient supercomputer overlord read the performance reviews of those two models and decide "Whoops, scrap that 'mimetic polyalloy' bullshit, clunky metal horror-bones are definitely the way to go"?
Yeah, that's much, much better.
The T-1000 essentially has no limitations as an infiltration unit -- as we've already mentioned, it can mime pretty much anything, but beyond that, it can get in and out of any place it wants simply by engaging "puddle mode" and sliding through whatever narrow entrance point is available. It wouldn't matter if the only way into a building was a tiny hole in a 10-foot concrete wall, it could just turn into liquid and drip the fuck in. But the T-X, which is supposed to be the T-1000's upgrade, has all of the physical limitations of a standard non-robot person. If there's no door, it has to either bust a window or gas up its breasts and try to jiggle its way through security. The T-1000 could come in through the damn water fountain.
Finally, when the T-X has its climactic battle against Arnold, this happens:
"Shit, I'm stuck!"
"Oh, wait, I forgot -- you're totally not invincible."
That's Arnold grabbing the T-X by its spine. He holds it in place long enough to detonate his own power core and destroy them both. It is literally the only reason the evil machine gets defeated -- Arnold is pinned by a door, so if the T-X didn't have a physical structure for him to wrap his meaty cyborg fingers around, he would have been helpless to stop it from killing his BFF John Connor. For comparison, here's what happened when he tried that same nonsense on the T-1000:
It totally didn't work, because you cannot punch liquid. If Skynet had improved upon the polyalloy design for the T-X (or just sent another fucking T-1000), it would've just poured through Arnold's fingers like rain and left him sitting underneath that door like a jackass. The only "improvements" the T-X seems to carry are a leather pantsuit and a built-in flamethrower, because if there was one problem with the previous two Terminators, it was their inability to kill human beings with their bare hands.
"Screw liquid metal, I totally need this flamethrower."
4The Transformers Have No Way of Detecting Each Other
In the three movies, we see the Transformers masquerade as cellphones, radios, cars, planes, construction gear and (somehow) slutty women. The point is, they adapt to their environment by blending in appropriately -- for example, Optimus Prime doesn't turn into a big rig when he's on Cybertron because nobody on Cybertron knows what the hell that is. They are also continuously at war, so regardless of where they are in the universe, Transformers should have a healthy suspicion of anything mechanical that isn't walking around on two legs and speaking with some hilariously racist affectation, or at the very least have some method of distinguishing which taxicab is a robot in disguise and which taxicab is just a taxicab. Their survival depends on it.
But they don't have either of those things. At all.
"Ooooooh, now I see that that car was more than meets the eye."
In fact, the Autobots go through most of those movies as if they've completely forgotten the fact that the Decepticons exist and constantly stumble blindly into ambushes that would be obvious even if the film wasn't about Transformers. Like here:
"I'm just a normal building-size truck. Also, this is the radio talking and not me. Shit."
That truck would be suspicious in a Lethal Weapon movie, let alone in a trilogy about giant camouflaged robo-monsters from beyond the stars. Yet the Autobots cruise right on into this construction zone, which is literally filled with Decepticons like Truckasaurus up there, and have no idea they're in trouble until the Decepticons start playing the theme from Road House.
These two factions have supposedly been at war for centuries, in a conflict spanning entire galaxies, and yet after all that time, they still have no way of spotting each other? They can't build some kind of scanner or even, like, tie a bell to any dubious machines? We're amazed that they aren't just destroying every car they see at this point, let alone allowing any to pull alongside them.
The best example comes early in the second film, when Alice (who is a Decepticon that has somehow managed to disguise itself as a girl that looks more unwashed than Megan Fox) hitches a ride with Sam inside Bumblebee, his Autobot protector. Bumblebee literally has a Decepticon inside his body that is actively trying to murder his friend and he is completely oblivious to its presence.
"Can I borrow some paint thinner and a washcloth? Soap just ain't doin' it this time."
What's most baffling is that there are definitely ways to detect Transformers, because the humans do it all the time. The Transformers have been on Earth for like two damn years and human beings have already figured out ways to track them using heat-seeking devices and scanners for the radiation that they apparently emit.
"Your testicles have literally melted from cancer. We can't tell if the cause is the robots, Megan Fox, your Strokes T-shirt or all of the above."
And that's just what the humans have figured out so far. The Autobots and Decepticons have been locked in their robo-clash for centuries and they have nothing. Technical institutes back on Cybertron really need to get on this shit.
