⚡️AI is liquidating the time value of human expertise. A professional career used to be an intertemporal contract. You sacrificed years learning something difficult because time created scarcity. Ten years of accumulated judgment could not be downloaded overnight. AI is collapsing that delay. When five days of elite reverse engineering becomes twenty minutes of machine cognition, the machine has done more than automate a task. It has destroyed the waiting period that made mastery scarce. The old equation was: time → experience → scarcity → bargaining power Now that chain is breaking. The expert does not suddenly know less. The world suddenly needs fewer experts. That is the rupture. And once this spreads across professions, the ladder itself starts to hollow out. Fewer juniors are needed to become future experts. Fewer mids are needed to support seniors. Eventually, the senior becomes a supervisor of machine cognition rather than the primary source of it. Then the machine begins absorbing the supervisory layer too. Civilization trained people to delay gratification in exchange for future scarcity. Study longer. Specialize harder. Accumulate knowledge. Become difficult to replace. AI is beginning to invalidate the final promise in that sequence. That is why the “learn plumbing” joke lands. He just watched the market price of a decade of cognitive accumulation collapse in front of him. AI is turning human expertise from durable capital into depreciating inventory.
