It was impossible to hunt enough game to feed everyone, so we invented husbandry and agriculture. Then there wasn't enough arable land to grow food for everyone, so our ancestors invented terraced farming and irrigation.
There's not enough space for everyone to live while being able to get to work, etc., so we invented high-rise buildings. There's not enough forests for everyone to burn wood to heat their houses, so we've gone through many generations of improved heating systems.
Humanity is always on the brink of disaster, but as the saying goes, necessity is the mother of invention. When the stakes get high enough, the market promises riches to whoever can offer a solution. This motivates people to think and look hard for it. That is the beauty of the market.
Search for discussions of Malthus and Ehrlich.
Now, with a centrally-managed economy, the only way to find a solution is through politics. Thus, we now have most of our cards riding on biofuels and ethanol for energy, since so much of the US Congress is in the pocket of Archer Daniels Midland, etc. That's a bold bet, staking so much on one narrow option. Of course we could be investing more in sources like windpower, but that would disturb Ted Kennedy's scenic view.
My point is that the market drives people to come up with the best possible solution. The only other option that's been found is to let corrupt politicians make the choices based on poor information and questionable motivations.
And if hafnium runs out, we'll have a great new business in scraping it off old chips to put on new ones. The atoms aren't going anywhere.
Helium atoms _are_ going somewhere (up!) but we can always get that in small from fusion if we really need it. Fusion is easy as long as you don't care about getting more energy out than you put in.
Over the past few months, I’ve gone from some optimism that we’ll be able to solve the environmental and climatic problems the world faces to complete pessimism.
Even if everyone on the planet were on board with the fact that climate change is real, and it will be disastrous, that soil depletion is happening and is effectively irreversible, it’d still be a hard slog to change it before mass death and possible human extinction occur.
But given that half or more of the planet doesn’t believe it, or doesn’t care, then there is just no chance at all.
So, what to do? Me, I’m going to selfishly enjoy the good times that are left, and support activities like establishing seed banks and archives of humanity’s achievements (because we have done some amazing things) in case there is any resurgence of human life or other intelligent life in the future.
But the hope of humanity even beginning to turn the tide against what’s coming? Evidence suggests it’ll be impossible. There’s too many us -- far, far too many of us -- and not enough who care about what’s happening, or even believe it.
"Lucky for me I'd been off-planet on vacation at the time of the war. There wasn't much to do. All the bowling alleys had been wrecked, so I spent most of my time looking for beer. One day I was out looking for a nice place to build a city for my children when I spotted a mutant in the forbidden zone. I landed my vehicle to pursue and destroy this genetic freak before he could warn other mutants in the underground caves."
This sort of article seems to be what I'd call "reddit bait" in that it brings out these sorts of fruitless discussions.
I found this article from 2008. http://www.physorg.com/news118491348.html It seems reasonable that Helium from the one place in Texas where most of it currently comes from may run out but the article eludes that there are surely deposits in other countries like Russia that haven't been tapped simply because there isn't demand.
Helium will run out in my lifetime. Look it up yourself.
Hafnium is likely to as well.
I'm amazed by the rah-rah capitalism types (not saying you are one of them) on this site who know so little.
