I don't know if it will happen like it says in there, but I know that we will run out of oil someday, that's a fact. The questions should be, will we be able to adapt fast enough? And how much oil is really left and how much did we burn already.

And the human race is known to wait until something happens in order to do something about it, so I guess this will hit hard as we won't be prepared.
