I however have hopes for the future. Our society is still locked in and "end of history" mentality that makes most of us believe that economically and socially we have reached the end of the road and that all that is left are minor tunings. The next "collapse" or "big" crisis, that can come from anywhere (not necessarily be a purely economic thing), may shake that belief from us.
I don't think we should be digging everything out of the ground we can, but I don't here anybody saying we are about to run out of anything.
Every few years a functional illiterate with disproportionate reach in media thinks that "current reserves of X" is a value describing the total amount of X available on the planet and that this can only ever shrink and will hit zero in our lifetime. The doomers scream and have a tantrum over our impending apocalypse for a year or two, then it fades into an embarrassing silence before repeating with theme Y instead.
Eventually we've rotated through the entire doomer alphabet and we're back at screaming about X again, as is the case with the OP article which I didn't read and never will but can reject in its entirety based on having seen the Doomer pattern a hundred times before.
We are still getting a lot of helium as a by-product of natural gas extraction. If helium gets more expensive, people will make a bigger effort to capture it.
Obviously that hasn't happened.
