Only tangentially relevant but had a discussion earlier today in which it was pointed out that spaced repetition learning like Anki decks are always miserable since you are constantly exposed to the things you are bad at and rarely see the items that are easy for you. More generally you might observe that it always feels like you suck at things you are trying to improve at because you are (presumably, ideally) challenging yourself.
"What can we do as a society to elevate the status of stay at home parenting?"
Can you explain why this would be desirable?
If the Boubas have an internally consistent definition then the Kikis are right to make them produce it so that a productive conversation can be had, the Kikis would no doubt readily supply their own if asked. I do not understand the instinct to suggest the Kikis are doing something not on the level here, productive discussions require work and sometimes rigor from both participants. If the Boubas are incapable or unwilling of doing their part it is a bit silly to blame the Kikis for not doing it for them. 
If you are imagining that the Boubas do produce an internally consistent definition and then the conversation devolves into whose is "right" then I would agree that both parties are foolish in that instance. 
Another point on your last sentence: in a near or post AGI world one might think that the value of the type of knowledge work (pure design as opposed to manufacturing) Nvidia does might start trending towards zero as it becomes easier for anyone with equal compute access to replicate. Not sure if it will be possible to maintain a moat on the basis of quality in software/hardware design in such a world.
Even if one accepts the premise that the purpose is not to educate children the education clearly still occurs and its effectiveness varries by school depending on a number of variables, many of which are controllable. Given that, you can increase how much the children learn without undermining the "true purpose" of the system, whatever one invisions that to be. To use your example, perhaps the children producing more reports actually does help them learn more. I am low confidence on that particular example but seems very possible to implement systems that increase educational efficiency below some threshold of costing current stakeholders material loses. I think your response here was too cynical.
Throwing in a bit of self reflection here, may or may not be of interest to anyone: I'm a straight cis-male with no body dysphoria but I really like the cutesy-anime girl oriented online trans community and associated culture and have found myself feeling that it would be cool to be a cute anime girl for what I think are similar reasons to those you outline (though I would not want to remain in that state permanently). It's interesting to observe how much I like that culture and would like to fit into those communities. I do wonder if I would entertain the idea of transitioning if becoming a cute young anime girl (or cute egirl, I suppose) was a possibility but I do not think resembling that is possible with my body now, and that's fine as I have no body dysphoria in the first place. I see eboys or softboys or femboys replicating a similar cutesy look in a way that seems half a step more achievable to someone like me and I have been exploring expressing myself in those kind of ways which I have mostly found pretty fun. I can confidently say no aspect of my interest is sexual or fetishy.
It sounds like I am probably ~5 to 10 years older than the OP here so these types of sizable online cutesy anime trans girl communities did not exist for me to be exposed to at that age (and I strongly suspect that I would have bounced off of them at that time), but I was extremely online in 4chan anime circles at that age and too idolized the NHK-esque hikikomori otaku lifestyle, so really quite similar to what OP describes in many ways. I cannot say I remember having any desire to play with gender expression at all until after undergrad, though I think it has been slowly increasing to a still rather mild (but high for a straight guy) level.
