Science fiction movies give us a glimpse at what could be better worlds. Worlds with flying cars, bartending robots, and ultra-powerful weapons so awesome that you couldn't help but grin even as you were getting annihilated by them. But even accepting that every one of these devices are possible, the consequences of using them would still be a freaking nightmare. For example ...
7The Matrix Would Be a Troll's Wet Dream
One of the rules established in the Matrix series is that, since we're all living in a computer simulation, anyone can write a program that affects the rules of the "game." It's exemplified by the scene in which Tank pops in a floppy disk (because this world ended in the mid-'90s) and Neo instantly gains the ability to do gravity-defying kung fu. It's like turning on a cheat code. The idea continues when Trinity learns how to pilot a helicopter in the same way, and Morpheus gains the ability to make those sunglasses stay on his face without the ear parts.
His nose is really sore.
That's the whole seductive appeal of the franchise -- most of us would probably accept living under the thumb of an evil artificial intelligence if it meant gaining the occasional ability to hack the very universe into awesomeness.
As long as you're on the right side of the hacking, that is.The Horrifying Downside:
In the first movie, the number of people who have this reality-bending ability is tiny, and they're all anti-Matrix freedom fighters using their abilities to free minds (even if, you know, they're leaving hundreds of bystander corpses in their wake). But if we generously accept the two sequels as canon, then after the third movie, the machine overlords allow us the choice to remain in the Matrix if we feel like it (because let's face it, the world outside kind of sucks). So anyone living in the comparative comfort of 20th century virtual reality is still subject to the rules of the game. Rules can apparently be hacked by anyone who has the time and dedication.
And those people are inevitably assholes.
Now there are all sorts of people living outside the Matrix -- anyone who chose to drop out and live in the cold, dark real world. So how do you think those people would feel about the ones who chose to remain in the pods? Remember that the first people with the urge to break out were all hacker types -- what do you think that crowd would do with their newfound powers? Imagine a reality in which the denizens of something like 4chan are actual gods, able to hack in at will. Imagine you suddenly start jacking off in the middle of a business meeting because someone from a higher plane decided it would be good lulz.
Take the blue pill and you see cat pictures all day. Take the red pill and you poop pretty much everywhere.
Hell, the software even allows a user to take over the body and free will of anyone inside -- the agents did it all the time. Imagine what they'd do with that power. If we were forced to choose between an advanced artificial intelligence or the whims of bored Internet teenagers dictating our lives, we'd probably say bring on the robots.
6 The Avengers' Helicarrier Would Destroy Everything It Passed
Heroes in the Marvel cinematic universe have two distinct advantages over regular folks like us: magical superpowers and technology that seems to be about 50 years ahead of what's available to everybody else. Take the helicarrier, for example. As the name suggests, it's an aircraft carrier that flies like a helicopter, an advanced fortress that can go wherever the heroes need it, while likely chopping up several thousand birds in the process.
"Half our operating budget comes from selling 'chicken' for McNuggets."
Of course, what geeks are interested in is whether it's technically possible for such an immense aircraft to exist, even with SHIELD's seemingly unlimited budget. And the answer is yes! If you don't mind obliterating everything between it and the ground.The Horrifying Downside:
In order to keep something as massive as the helicarrier afloat, you'd have to achieve a level of downward thrust that would peel the very flesh from the bones of anyone standing underneath. Scientist Phil Plait, who blogs as the Bad Astronomer, figured out the physics and concluded that, in order to keep the helicarrier in the sky, you would need a power supply equivalent to a trillion watts, which is enough to power a billion homes. But that's no big deal, since they've got Tony Stark's arc reactor (or something) to power it.
We think we just figured where Stark's hordes of illegitimate children go.
But the problem is that no matter what's powering the engines, the physics don't change: to stay afloat, an equal amount of force has to be pressing downward. But where standing under a helicopter would merely mess up your hair, the downward thrust of the helicarrier's rotors would basically scour the earth clean underneath it. It'd look like when you use a leaf-blower on your lawn, except the leaves are houses and shopping malls and screaming civilians reduced to a viscous red sludge.
This scene ends right before the ocean turns red and scores of dead dolphins float to the surface.
That would also kind of render the helicarrier's cloaking ability useless, since it could be located by following the massive hurricanes that follow in its wake. In short, if the government were to create an aircraft like the helicarrier, they wouldn't need to arm it with missiles -- simply fly it over a war zone and let physics do the rest.
Speaking of which ...
