Did I say I want to mock them? Tell me more about your ability to foretell the future....
Your OP is openly mocking, and it has nothing to do with "telling the future". It is simple reality. Something will come, a supercaldera, a comet, disease, scientific accident...
If we are not ready to deal with it technologically these people will survive while those of us who are not survivalists will not.
Humanity has suffered a near extinction in our short existence on this planet?
When was that?
Here is a link you should read:

Roughly 70,000 years ago, give or take a few thousand years, an enormous eruption occurred in what is now Sumatra, leaving behind Lake Toba (the crater lake pictured above). The eruption coincides with a population bottleneck that is often cited as the reason for the relatively low genetic diversity across Homo sapiens sapiens. Research suggests as few as 2,000 humans (actual homo sapiens) were left alive by the eruption and its aftereffects.
2,000 total humans on the planet after one volcanic eruption... and that is just one of the events. Earlier events nearly killed off the Homo genus several times. If any one of them caused full extinction rather than just a population bottleneck (that one with 2,000 humans is one of epic proportions), we would not exist today.
I watched it on the Smithsonian Channel a while back, some show with Hawking stating that the only way to ensure our survival is to spread humanity to more than one solar system.
However events like
this one happen, pretending they don't exist is just foolish. That particular event linked there killed of 90% of all animal and plant life on the planet...
