For a growing majority of cognitive tasks, the economic value of a human is not just lower than an AI. It is negative. Humans are "metabolic engines" requiring food, sleep, and management. AI is "non-metabolic labor" requiring only electricity. When AI outperforms humans at a fraction of the cost, "a human is not just more expensive than an AI; a human is a liability." --> human value lies in defining worth, not creating output. [[Defining worth > creating output]]
