Fears of AI displacing jobs overlook decades-long declines in labor force participation driven by falling birth rates with a twenty-year lag. Machines are primarily filling workforce gaps created by retirements and demographic shifts rather than displacing active workers. Synthetic labor removes traditional GDP ceilings tied to population growth by allowing productivity to compound independently of human workforce expansion. This decoupling creates an "Economic Singularity" where economic output no longer depends on demographic trends, fundamentally altering long-term growth equations.
