Aubrey de Grey, Michael Copeland
Aubrey de Grey established the Strategies for Engineered Negligible Senescence (SENS) framework to shift gerontological focus from slowing metabolic decline to actively repairing seven specific categories of cellular damage that cause death. Drawing on his background in software verification, de Grey advocates for high-risk therapies like stem cell treatments and bacterial enzymes, arguing that current funding systems inadequately support such transformative research. He contends that these biological interventions, alongside future technological alternatives, will extend human lifespan without exacerbating overpopulation, citing rising planetary carrying capacities from renewable energy and artificial meat production.

Aubrey de Grey: "The cost effectiveness of anti-aging research"
Aubrey de Grey proposes a "maintenance" strategy within the SENS framework to systematically repair seven categories of cellular damage, challenging the inevitability of aging by targeting its biological root causes rather than treating individual diseases. This approach aims to achieve "longevity escape velocity," a threshold where therapeutic advances outpace degeneration to eventually reduce mortality from aging to negligible levels comparable to accidents. By shifting billions in global healthcare spending toward preventative rejuvenation, the strategy promises to extend healthy lifespans significantly while mitigating economic costs and addressing ethical concerns regarding overpopulation and identity.
