This is a strange OP arguing against something nobody has, to my knowledge postulated.
It’s like saying AIBU to say that black is not white, it is black.
If OP was prompted in her argument by my humble od, let me say that was not what it was about, as perhaps more careful reading might reveal, but also prompted by Shakespeare's Seven Ages of Man whose theme is the cycle or circle of life. Birth, childhood, lover, soldier, justice, “senior citizen”and at the end of his life, facing death
I felt there was room for a female take on this premise, after all, not only boys and young men go “unwillingly to school”or become “young lovers”
My starting point was that there are certain stages in a woman’s life, certain milestones as it were and most of us on GM have experienced those. At this juncture in my life I am perhaps in more contemplative mood than usual.
I too had a successful career as a secondary teacher and HoD but when I retired I did not for a moment kid myself that that was my sole raison d’être. Or indeed that I was not ENTIRELY replaceable and replaced.
But you only have one mum.
What can be more important to the continuance of human life on Earth and to society than the birth of each successive generation and the responsible upbringing of our citizens?
If all that mattered was our professional lives then we would surely be happy to be euthanased instead of a leaving do (and think what THAT would save the country’s finances !)
Life on Earth is dependent on procreation , our legacy might be a painting or work of literature but what lives on is the genes.
Apologies of course if this is way off the mark of what OP intended, but arguments and empty rooms spring to mind.
