The Longevity Escape Velocity Calculation Is Wrong — It Assumes Linear Progress in a Power-Law Problem

Aubrey de Grey's longevity escape velocity (LEV) concept assumes that if we can add more than one year of remaining life expectancy per calendar year, we've achieved escape velocity. The math seems simple. But it's built on a linear assumption about progress rates that doesn't match how biology works.

Each additional year of life extension gets exponentially harder. Going from 80 to 90 is manageable with lifestyle interventions. 90 to 100 requires addressing cardiovascular disease and cancer. 100 to 110 requires solving neurodegeneration. 110 to 120 requires fundamentally rebuilding cellular maintenance. Each decade demands solutions to problems that are qualitatively, not just quantitatively, harder.

Hypothesis: The difficulty of life extension follows a power law, not a linear function. Achieving LEV will require not incremental progress but phase transitions — completely new technological paradigms (nanotechnology, whole-brain emulation, synthetic biology) rather than extensions of current biomedical approaches. The "escape velocity" metaphor is actively misleading because it implies a smooth acceleration rather than discrete jumps.

Prediction: Progress in maximum validated human lifespan will plateau at ~125 years using current biological approaches. Breaking past 130 will require technologies not yet in preclinical development.
