There's a difference between known unknown with high variance and known unknown with low variance. As I understand it, astrophysicists have a non-controversial model for how much gold is present on earth. Geologists probably have a reasonable model for how much gold is easily accessible.
- saalweachter 6y agoThe last time I looked into this, the mined gold supply seemed to be increasing at a fairly steady 2% per year, over the last N decades I was able to find good data for.
