[ExI] it was the best times, it was the best of times

[John Clark]

Eugen Leitl, aka Dr. Doom, showed us a graph purporting to show that
because of worldwide shortages copper prices are going through the roof:

and it is a ugly graph no doubt about it, but if you look at a more recent
copper price graph that shows the last 5 years in greater resolution things
look much more cheerful:

Today silver costs $22.41 an ounce, 33 years ago in 1980 silver cost $49.45
an ounce, adjusted for inflation that would be about $138 per ounce.  And I
still haven't heard from Eugen if he's accepted my bet about a worldwide
uranium shortage by 2020.
