1. Death as an evolutionary feature
Many commenters argue that a limited lifespan is not a flaw but a necessary trait shaped by natural selection.
“we might find out the hard way that having an expiration date was a feature of our species, not a flaw.” — moralestapia
2. Societal and ethical concerns about radical life extension
Participants worry that dramatically extending life would exacerbate inequality, empower tyrants, and strip life of meaning.
“If something like this ever becomes a practical application on the organismal level, the octogenarian dictators of the world will rejoice.” — layer8
3. Practical limits make true immortality unattainable
Even if aging were halted, accidents, entropy, disease, or biological trade‑offs (e.g., cancer) would eventually cause death.
“Curing aging doesn't stop death entirely. There's still the attrition of living in the physical world. Some portion of the population will trip and break their necks every year.” — idle_zealot
