Technological advancements are all good, because knowledge and discovery are never a bad thing. It is only when you introduce a human vice, such as greed, into the mix that technology's impact on society can become a troubling thing. That being said, the transistor is the single most influential technological invention and its impact on society has been that many other inventions used it to change our world forever.

A Mixed Bag

As some technology caused horrible injuries to men and women in war zones, with the bombs, increased firepower and chemical and germ warfare it brought about, some led to new and wonderful ways to heal and repair the human body, ease pain and suffering and clone new life in labs across the world.
