> If you're right about the cost of electricity "staying the same" — by which I assume you mean that, in the US, it increases in line with the BLS CPI? Yes I meant real price, not nominal. US electricity is somewhere around a third from coal. I would be interested in a study showing a 15-30x increase in similar-quality construction materials. The fixation on gold makes no sense to me. It's just a commodity, not a super useful one either. Gold's price floats wildly based on people's fears. It's not like everything became 4x more expensive between 2000 and 2015.
