'Getting' peak oil

Found the following quote in this article http://canadiandimension.com/articles/2006/07/07/555/
and it gave me pause:

'Those who “get” Peak Oil typically experience a profound paradigm shift — a reorientation of their thinking about the world. At the core of this shift is the recognition that humankind is entering a period of change unlike any in history.'

It causes lots of questions:
- What does it take for someone to "get" peak oil?
- How good is this definition of someone "getting" peak oil?
- Do I (you) get peak oil?
- Are the Amish the only ones who really get peak oil?
- What should one do if they get it?

I guess that last one is the point of this blog, isn't it?
