To the casual HN reader - my recommendation to you is to neithet laugh at nor dismiss out of hand analyses such as this (even as logic intrinsic to them merits as much picking apart as any other analysis one sees everyday on HN).
Robin Hanson's description of long-lived stars (usually strongest in infrared - i.e. the 3 stars our eyes lack the spectral response to see for every 1 star that we do see when looking into the night sky) significantly updated my priors on the likelihood of intelligent, non-human life roaming about the cosmos.
Do those red dwarves have the heavier atomic elements necessary to make diverse biological interactions, on a planet geologically active enough to protect the biosphere with a magnetic field?
I recently encountered a description of how Earth relies on the remnants of some interactions between stellar remnants which would have been far rarer early on, even if red dwarf stars were present for so long.

tl;dr: Red-dwarf stars have been around -- with all that goes with that.. -- for much, much longer than our sun.
