How did technology change the world?

I think your question should be how does technology change the world as it is doing so every hour of every day. You posted this question with a computer which was the stuff of science fiction only thirty years ago. Technology is advancing so fast your computer was probably obsolete a week after you bought it.|||Well, let%26#039;s just think about that. Duh! When I was a child no such thing as colour tv. Now we have computers, mobile phones, www, digital tv, sat navs.............does that give you a few ideas?
