As I recall we've had about a decade of oil left for the last 50 years so I guess we always will.
So watch out. The end will come without warning. You'll be driving down the road and your car will stop. Out of gas. You'll walk to a gas station to see a sign: "Completely sold out". You'll look around and every single car and truck will be stopped except for the electric ones because no body in the world generates electricity by burning oil.
Sounds silly but lots of people swear by it.
The point of peak oil is that we won't run out, but we will find the cost rising from now on, and at some point oil will no longer be considered a resource. Then we crash.
