Save me a piece of that corn for later

I heard on the radio about this guy that thinks the world is on the brink of a change. He was saying how when people are living in history the general perception is that every change is slow. There are people that point out the real history does move slowly sometimes but is broken with periods of great, quick change.  We are about to experience one of these he says. 

I wonder what will happen? What will the future hold?
