Simon–Ehrlich wager - Wikipedia, the free encyclopedia: "It's not clear if Ehrlich consulted with economists. If he had, the flaw in using commodity prices as the best way to understand biophysical limits might have become obvious. Many economists understand the principle of substitution and the dynamic influence of technology with respect to commodity prices. For example, in the absence of any new technologies, copper prices would indeed be expected to increase as growing economies demanded more copper to meet the needs of expanding communications networks and plumbing infrastructure. Technological changes mitigated much of this expected demand as fiber optics replaced copper wire networks and various plastics replaced the once ubiquitous copper pipes throughout the construction industry."
