Are we really running out of helium?
One part of this I've never understood: I'm often told that I shouldn't buy or enjoy helium balloons, as it's a waste of important helium. But such a balloon costs almost nothing, if helium is so scarce and so important, shouldn't that be reflected in the price?<p>At least that's how stocks work. If something will be in high demand/price in the future, it will shift and be in high demand now.
