 Asset manager Jeremy Grantham wrote that if the Simon–Ehrlich wager had been for a longer period (from 1980 to 2011), then Simon would have lost on four of the five metals. He also noted that if the wager had been expanded to "all of the most important commodities," instead of just five metals, over that longer period of 1980 to 2011, then Simon would have lost "by a lot." He concluded, "So, please "Cornucopians," let's not hear any more of the Ehrlich-Simon bet ... Ehrlich's argument was right (so far)."[12] 
 :The link provided still doesn't work. Even if the link works, there are just but one problem with this source: Saying that Simon would have lost in a longer period does not prove anything and is quite irrelevant to the wager in question. The wager was set in 1980 and ended in 1990, if Simon had agreed to extend the wager by 20 years then this would be a different story but he didn't. The article already mentions this under the section "Aftermath" with a much better source (the Economist) and a more NPOV description. Jeremy Grantham certainly didn't prove "Ehrlich's argument was right", he was just taking cheap shot at Simon who clearly didn't (and couldn't since he was long dead) bet on the prices of 2011.
