I think this only makes sense for high extinction risk. If extinction risk is less than 1 % per century, or less than 10^-4 per year, it would allow for a life expectancy longer than 10 k years. This is nothing on a cosmological timescale, but much longer than the current human life expectancy. If a generation lasts 30 years, it would take 333 (= 10^4/​30) to reach 10 k years. So extinction risk has a pretty small impact on one’s life expectancy, and those of one’s children.
