O.K. In gatheringlilacs utopia, work would be more evenly distributed, there wouldn't be such a division between the work-rich and the work-poor. There also wouldn't be such an emphasis on acquiring skills whilst still relatively young, and in such intense blocks. You really could dip in and out. I do think that would rely, for a variety of reasons, on a more equitable distribution of wealth, and would help perpetuate that.
I also think that it would lessen the fear of an impoverished life, which I think drives a lot of the current model of trying to squash as many experiences as possible into the younger, childless years as possible.
I think you really would be able to kick off for 6 months/a year, with your child, to some other part of the globe, taking advantage of all those modern possibilities.
I freely admit that this is (a) utopia. Quite possibly unachievable. And a fantasy that is (very) marked by my own standpoint (Western, educated, etc.).
But I put it out there just as a "for instance". And to demonstrate that economics plays a large part in how our current model and conceptualisation of motherhood is determined.
My model is also very indebted to the work of two SF writers (Kim Stanley Robinson and another one) who start out with the idea of "what if humans had very long lives" and then start to envision how that would change human societies and life-models.
I really don't get why asking if we might envision how society might be re-modelled, to be more women-with-children shaped or to take us into account in a more thorough-going (as opposed to "added-on-as-an-afterthought) way instantly labels me as a technophobe. I honestly think that is being read into my posts, quite possibly because the female-body-with-children is over-conceptualised in opposition to technology.
