A favourite of science fiction authors is to challenge our socio-normative values. It doesn't take an author to do that, but a weaver bird doesn't listen to authors or any numbers of creatures which refuse gender-normative classification. The one with the harp makes the nest and the one that lays inspects it. As to the weaver's motivation, it's worth noting that certain creatures successfully minimize their investment in terms of attracting a mate. As one who has no nominal cause for attracting 'a search engine', except insomuch as my harp has had little use, I come to think that even though many nests are rejected, much to his frustration, he enjoys the activity.
Perhaps weavers are not clever enough to minimize their investment; the same might be said about those who persist with the norm called an engagement ring.
Thus for the frontier called the ring; as to the frontier called the threshold, weaver hens, and those at least as intelligent, would have only one response to a sketch of a nest.
But some people truly don't seem to know the difference between a chick and an egg; which is to say self-analysis is not within everyone's reach. If a weaver hen didn't know which came first she might do her laying on the wing just as an experiment.
Thinking of eggs in the sky, we move them into orbit. But the government funded animal anti-cruelty league wouldn't have us taking birds into a weightless environment. And they have far too many overheads to help fund a space habitat.
It's worth noting that artificial gravity has not been taken to the proof of concept stage. While I'm thus tempted to recommend against science fiction altogether, I don't see any harm if a boy is allowed to make his own selections. As long as they don't stretch believability so far as to suggest we'll see any results to get excited about in our lifetime.
Futuristic scenarios are useful devices for computer games. One of my favourite was one that involved the mining of the planets. In fact I tried that game out with a stereoscopic headset. Once.
Getting people to see things my way is a reminder of a throne that was removed by the sword and a reminder that whether people accept what you say at face value or not is quite improportionate with whether they like to hear you talk or not.
I'll have to use a thesaurus to find a better word than the italicized one, that was assembled in a time of extended peace, in which days people got the idea of getting rid of class as a --. I leave the obvious word out because once we allow ourselves to create new words we don't know when to stop; which gives me a clue as to when I should.
