So in 50 years, the reserves are going to be done. And yet 50 years down the line, you find that our consumption has gone up significantly more. We've consumed maybe fivefold, five times more than what we consumed 20, 30, 40, 50 years ago. And yet the price of oil is gone down and the proven reserves of oil continue to go up. What has gone up also is human wages. So what this tells us is that the real scarcity is in the scarcity of human time. There's no limit on how much oil or gold or copper we can have, practically speaking, except how much time we dedicate to that. Because there's an infinite ocean of all of these things under the crust of the earth that we could just keep digging out. But we're never going to get anywhere near finishing 1% of that because it's way too expensive in terms of our time. If we wanted to keep digging into the gold to find all the gold or all the copper, we could starve ourselves as we stop producing anything else and keep focusing on only making more and more and more copper or gold or whatever it is. And we still wouldn't make a dent in the gigantic stores of this that exist on earth.
