Does anyone worry about the fact that many of us not passing on our biological legacy?

MGTOW is the enlightened path and whatnot, but our ancestral line dies with us if we don't have kids. A lot of us are intelligent, capable people, and our genetic line is dying whereas Tyrone's and Stacey's are being perpetuated into the next generation

That's not to say MGTOW parents are always capable of raising good kids or raising kids who go the MGTOW way, but is our worldview inherently self-limiting since it involves a clause of literally not duplicating ourselves like others do?
