There are 1.65 trillion barrels of proven oil reserves in the world as of 2016.
The world has proven reserves equivalent to 46.6 times its annual consumption levels. This means it has about 47 years of oil left (at current consumption levels and excluding unproven reserves).
This means that the oil is going to run out in our lifetime

Update: It is infact not true (or just partially true), because it only considers already known oil reserves that can be pumped out with current technology.
There is more oil that can potentially be used as technology and infrastructure advances, so the estimate of 50 years is wrong.

“Peak Oil” they used to call it. Lots written about to collapse of everything after Peak Oil. Been predicted since at least 1970’s.
Now we need to run out for our own good.
Peak oil was about conventional oil. Had we not discovered other sources and methods for extraction then we likely would have run out. And running out isn’t accurate, it’s just that oil becomes harder to extract and thus too expensive for regular uses.
There are many things that were predicted as a collapse factor that we then innovated solutions to break past those barriers. We’re too smart for our own good, because each time we find new ways to keep going we make things worse and get ourselves even more into a dead end. When we do “run out” of oil of any type, which will happen at the growing rate we use it up, will we be smart again and find replacements for all the things petroleum is used for (not just fuel)? One important one being fertilizer to make food grow in our otherwise barren soils. Fun fact: people need to eat to live. Most people in the world, especially the western world, exists and survive because of food thanks to oil.
Lastly, we would have done so much better post-collapse if things had happened naturally with a smaller population and less damage to the environment. The higher you fall, the more it will hurt, and we’re damn high now compared to the mid/late 20th century.
In other words, we did hit Peak Oil and that’s what caused the development of things like fracking, oil sands, and deep ocean drilling.
Peak oil was reached locally, not globally. Enough need to drive innovation, but not all of the fun aftereffects predicted.
I point this out as “peak oil” was more than just “no oil”, and I don’t want that lost on the young ones. It was about the collapse of everything dependent on oil.
Otherwise yes.
You are correct. It is worth reminding others that humans nearly went extinct twice.
