I think the way people solve them is that they have pre-programmed robotic invisible hands doing everything for them.
Shhhhhhhh.
Anyway, what I used to do if I couldn't solve them (this was when I was around 12) was I'd take it a part then put it back together. It's better than taking off the stickers.
why do people think that when someone knows how to solve rubik's cube their smarter then most people in the world?
They assume that you didn't look it up on the internet (or learn it from somewhere else), because they don't know there is a certain pattern to it. My fastest time is 50 something seconds, But I haven't done it in a long time, so I'm probably very slow.
I agree with you. And there are websites where you can learn the solution.

Probably because a lot of people can do just a face of the cube, or because these people don't want to spent hours trying to do it. Or because is a puzzle which is, for lots of people, very very difficult to solve.
