Often technology is shown in science fiction on TV and movies with very little real effect. People can teleport from place to play or cut through walls with laser swords without thinking about the repercussions of how this would effect everyday life. Some of those changes would be good, these are the ones which would be far to dangerous for modern human civilisation.
10. Flying Cars
These are one of the less dangerous of the dangerous inventions on this list because in large part the people who got killed would be killing themselves. Still, if you've been on the road recently you know just how bad of an idea it would be to allow these people a flying car. Also, imagine your parents trying to understand how to program the AI which ran it if we went that way. My
parents still have trouble with the TV remote.How it could be good
- long lines of cars in perfect formation of cars in long rows, floating traffic lights, and getting to work far faster.How I imagine it
- They have finally worked it out so that the constant fender benders and bad driving don't get me killed in the chaos of the sky where thousands of cars go in thousands of different directions, i get in my car type in my destination and halfway there the engine dies. I plummet to my death. You think it's annoying when you have car trouble now, try it at 10,000 feet.
Microscopic robots which are already being worked on. They can go inside the human body or create machinery thousands of times smaller than any human could hope to. More importantly they are able to copy themselves so that you don't have to constantly replace them.How It could be good
- People inject themselves with these devices and can heal in seconds, become super strong and smart. aging stops, computers become thousands of times faster thanks to micro circuitry, and nearly anything can be made by these tiny helpers.How I imagine it
- Assuming again that the grey goo scenario in which nanites reproduce until everything on earth is a nanite won't happen I go to the more annoying problem with these, adware, spyware and viruses. You think that pop ups are annoying on your computer then imagine what happens when hackers start to put them into the nanites which are improving your vision, constant popups advertising Viagra which you won't need because the nanites have already made you perfectly health but which they continue to put out because 1/20th of 1% of the population still fall for them.
This technology appears to be possible at some point in the future. New tests have found that they can bend light around people. The technology today makes the person inside invisible and isn't completely useful but it's likely to happen at some point.How it could be good
- Everyone gets a great view. You could observe wildlife without interfering with them.How I imagine it
- Security cameras are bad enough when you can see them. Now they are everywhere and you can't see them. No one one has any privacy anymore and every military weapon is completely invisible. You have to go through infrared scanners to get into everything.
7. Weather Control
Since people began to predict the weather they have thought about what it would be like to be able to control it. From the space shuttle being delayed due to weather to thousands of weekends ruined the idea of being able to control the weather is a great idea.How it would be good
- It only rains at night when everyone is asleep, there is never a drought, snow days are planned weeks in advance and no one is ever killed by hurricanes or tornadoes because they are harmlessly routed into empty sections of land.How I imagine it
- No need for wars, we don't even have to use tornadoes lightning. We simply just turn off the water for a few years. People starve to death and the land turns into a desert and that's all assuming that our messing with the weather doesn't cause huge unexpected changes in the weather in other places.
Push a button and get anything you want. A replicator rearranges matter into anything you want.How it would be good
- No one ever goes hungry and you get what you want every meal. Saves hours a day and you never have to go to the store because you can simply push a button.How I imagine it
- I don't really care that the economy collapses and every Wal-Mart in the country is closed, but you think Americans are fat now imagine what happens when you can eat anything you wand anytime you want and you never have to leave your home.
4. Artificial Gravity
Who knows how gravity really works but at some point it might be possible. this isn't the minor technology that it typically is seen. being able to control gravity could change everything.How it would be good
- those flying cars might not fall out of the sky, we could move huge amounts of cargo with anti gravity hand carts and space travel becomes cheep as we simply turn off gravity and float into the sky and walk around the ships like we're on earth once we get there.How I imagine it
- Want to destroy a building you don't need explosives or planes, simply adjust the gravity on one part of the building. Any technology this revolutionary is going to be used not only by our military and others and that's all assuming that someone doesn't alter the orbit of the earth or rip apart the earth with it.
3. Time Travel
Zipping up and down the time stream is problematic in TV and movies because of how complicated it is so it hardly seems any point in explaining how it would be dangerous which is why it's not higher on the list.How it would be good
- History could be revised to a more correct vision, we could pull people who are about to die out of time into ours to keep them alive without changing anything and collect lost masterpieces.How I imagine it
- We don't need the butterfly effect or time criminals to cause problems. How I see it is that we step into our time machine power up the ten nuclear reactors which power it and jump backwards through time and find ourselves millions of miles from earth because for those entire thousand years the earth has continued to move and even if we solve that the government uses it to spy on not only on what you're doing now but what you've ever done.
Orbiting satellites can be used to get from anyplace on earth to anyplace else as well as getting into orbit cheaply.How it would be good
- I've always wanted to visit the pyramids and walk the streets of Jerusalem. Americans would actually begin to understand the rest of the world. Troop moment becomes much faster and cheaper and they can go home at the end of the day.How I imagine it
- You think security is bad now imagine what it would be like when people can teleport in. Concerts, sports even movies become next to impossible to sell tickets to and money disappears out of every bank in the country. Sections of buildings are teleported away collapsing the buildings. Every trouble in the world becomes a local problem so the instability of any place in the world becomes a problem for everyone.
The most dangerous technology ever thought of. Step into any world you want, live out your fantasies. Become James Bond or explore the stars without ever leaving your home.How it would be good
- This ends most of the problems of the things on the rest of the list. People don't have wars anymore because they can just go into a world where everything is the way that they want. Every skill can be practiced until you're good at it, doctors become experts without having to learn on the job and people are happy all the time.How I imagine it
- Holodecks become universal and 9 and a half months later
the last human child is born. People never interact with anyone directly. At best they enter into massively multi player online holodecks where they talk to other virtual people. Research stops because you don't need to invent things that actual work when you can program it into your holodeck. No one cares about success they already have everything they want. The human race goes out not with a bang but a whimper, but at least they are happy doing it.
