"Who controls the past, controls the future" - George Orwell

To me, this quote has a bigger meaning than you realize. My interpretation of this quote what ever happens in the past can change the future in many, many ways. A good example of this is the short story "A Sound Of Thunder" by Ray Bradbury. In this short story, technology has gotten to the point where time travel is possible. The company, "Time Travel Inc.", uses this machine to travel back in time to hunt rare animals. One could go back in time and hunt buffalo when it was plentiful in the old west. Well, the main character, Eckles, wanted to hunt dinosaurs. to be more specific, he wanted to hunt and kill a Tyrannosaurus Rex. But something goes wrong. Eckles didn't realize what he was up against and chickened out at the last minute. He then wonders through the prehistoric jungle and steps on a butterfly. When they return to the future, they discover that time has forever changed. America is now run by a dictatorship instead of democracy. Even the way we spell things changed. All because a guy stepped on a mere butterfly in the past. That is a good example of a butterfly effect, don't you think? If you step on a butterfly, you change the future for the worst.

The Veldt (Found in the book "The Illustrated Man")

Technology isn't a threat to our society. At least, not yet. It has led us to new discoveries. To cures that were, before the technology we have today, unknown. But it can get out of hand. "The Veldt" is a perfect example. In this short story, a family of four decides to buy a fully automated house, complete with a nursery for the children. This nursery is the main problem of the story.  It takes the imagination of whoever occupies the room and puts it on the walls, creating your own virtual-reality dream world. Add that to the house that does every single thing for you, and you get a very lazy, spoiled family. But one day the parents get sick of their children's spoiled behavior and decide to turn off the house and take a vacation. Big mistake. Instead of immediately leaving the home after packing, they decide to let the children play a little longer in the nursery. The parents were murdered by the children's dream world, thinking that when the children called for them, they were in trouble and needed help. See how out of hand our own creations can get? In my opinion, we should limit ourselves to the amount of technology we use. That way we will avoid becoming lazy and spoiling ourselves to the point of no return.
