I've had the idea for this thread for maybe a year already, but now I figured the time is right.
So, what will be the key elements in this decade that will set the conception for future generations and ourselves? In other words, like the topic says, what will we remember the 2000's for? For example, we remember the 80's for awful (no offense) hair metal, the 70's for disco music and the 60's/70's for the Vietnam War.
I think some crucial things are obviously the Internet, 9/11 and the invasion of Iraq. I'll leave the rest for you to speculate.
