You are just flat out wrong. While IQ alone is not a guarantee of success, other qualities like work ethic, goal orientation, etc., are every bit as important, all other things being equal, high IQ DOES correlate to greater success. It is possible that one study that you saw did not show this, but this has been studied a lot, and ALL the studies I have seen show a correlation.
You missed my point entirely. My point is that the price mechanism ensures that resource consumption is always sustainable. As resources get scarce and harder to extract, the price rises. The rise in price can be HUGE. Right now we burn coal and oil for instance, for energy because it is cheaper than the alternatives. If demand increases outstripping production sufficient to cause a price rise of only a factor of three, oil and coal will no longer be burned for energy, as the alternatives will be cheaper. This price point would be reached LONG before there is 'no more' coal and oil. The same principle applies to all other resources.
We never get to the point where were run out of things that get scarce. Instead we find alternatives. The price of the alternatives might well be high, but they will be cheaper than the original resource. The higher prices in turn serve as a break on consumption. A free market ensures that the system is sustainable. Only to the degree that states attempt to intervene in the price mechanism, or societies that simply never had such to begin with, can you wind up with a situation in which resources get completely used up.
A climatologist, likely with a political agenda, a math grad student, and a political science BA, put together a model that shows that if growth trends continue in a finite system, the system breaks. No shit sherlock! Except that such growth trends do NOT continue. Any increase in resource consumption results in an increase in price. Any increase in production results in a reduction of price. If the system gets to a point where consumption outpaces production then the price rises, and it can rise a lot! This results in people using less of the resource and finding alternatives.
Any such models that are built without the input of an economist should be automatically discarded as being total BS.
There are 2500 tons of gold mined each year on earth with a total supply of 165,000 tons already mined. It will be quite a while before asteroid mining will make any appreciable dent in this supply, and until it does, it won't have much of an effect on it's price.
Meanwhile, the most money to be made from asteroidal material won't be their importation to Earth. It currently costs $10,000. a pound to put material into orbit. I expect virtually everything mined off planet will actually be used for off planet construction and manufacturing, including gold.
It was a few decades ago, but in my teens I had occasion to spend a weekend at a fireman's weekend where a great many and varied workshops were being given on any number of esoteric aspects of firefighting, and some of the more mundane. I took some of the mundane workshops on forest fire fighting and such. But I made my weekend more of a relaxed affair so I would have time to wander and see what everyone else was up to.
One group was busy creating fire tornadoes, and putting them out. But what I am referring to here, is nothing at all like what is featured in this video, or anything at all like Hollywood has ever dared venture.
The group was training in how to assault oil fires and extinguish them with a water hose, which is no mean trick. To make matters more complicated for them, dead center of the oil fire was a husk of tanker truck tank. This sat in the middle of a concrete pool ~10 meters square (30' x 30'). The pool was filled with six inches of water. The instructors would dump a full oil drum of oil into the pool, creating an oil slick that covered the entire surface. The training crew ready, they would toss in a match.
Now THAT is a fire tornado!
The result was a literal tornado of fire, a veritable solid pillar of flame that would do Moses proud! Thirty feet in diameter, this vortex roared so loud you could barely hear the shouted commands of the fireman as they assaulted the monster. It ripped and twisted, the spiraling cylinder reaching easily a hundred feet or more, straight up. The flame was dense red, and so intense there was nothing opaque about it. Pure fire, at it most intense.
I sat there for hours watching as they put it out, and lit up another, over and over.
