Just because it's Friday, I'm going to be lured completely off-piste by the feminist-baiter.
OFF-PISTE ALERT
So, for much of history, and much of present-day reality, if considered globally, the struggle for mere existence and continuation has been gruelling. If you don't believe me, read "The Bohemians" - the section on cooking in the Edwardian period.
From a Darwinian perspective, which is most important? Making sure the young survive to reproduce or inventing cultural prosthetics (the wheel, political systems)?
Ans: Both.
Of course, those whose job it has been to ensure basic reproduction have been rendered largely invisible and unsung in history. The only monument to their numbers is basically the swelling of the species.
But, hey, it's taken a long, long time (a testament to just how hard it was to ensure that basic survival for sooo much of our history), but now, in some place on the planet (and let's remember, it's only some places) and for some groups, there are enough cultural prosthetics about to free large groups from the basic struggle of reproduction. But it is very, very recent.
Of course, there are women who have contributed to the field of the creation of cultural prosthetics, and of course they are limited in number. It's been said countless times, but they tended to be the ones who were free of the task of reproduction.
Seriously, I hate the fact that your post seems to be oblivious to how important that role was, how vital and time-consuming. It consumed whole lives because it was bloody difficult, but so necessary it was worth the sacrifice of entire lives. We wouldn't be here without it.
Your blindness repeats an enormous historical condescension towards the enormity of that task. not surprising since writing history falls into the arena of cultural prosthetics. As does the task of valuing, sadly.
But I do foresee a future where the former reproducers are going to seriously make a mark in the field of cultural prosthetics.
