Sorry nugget.were not going to run out of gold silver oil or gas or anything in this finite world.
The fact is we get better and better of mining/extracting at the same time better technology that nothing is running out anytime soon.
Jimmy Carter said the world will run out of oil by 2011 in 1977 yet we have found copius amounts to last decades still.
Lol.
The market decides what is needed.
Eg, electric cars now.
