> People's role in society shouldn't be determined by their biology,

Why not (even if only partially)? Biology at the individual level has physical consequences, which necessarily affects the available roles and roles chosen. It makes no sense to expect that this relationship is different in aggregate.

Because your biology doesn't determine your destiny within society and the interests of liberty is not in tying you to it. For instance; a woman is entitled to choose not to have children, for any reason or for no reason at all. While it is a biological fact that only women can have children (or indeed can breastfeed, etc.), it does not follow, as a fact about how we conduct our society, that women are uniquely capable of raising children, or that it is their role within our society to birth & raise children. When we structure our society in an essentialising way, we cause create injustices for both men and women (to say nothing of trans and nonbinary people, who are erased by these essentialized framings, which for instance can lead to them being discriminated against in the adoption process), though women bare the vast majority of them.

You're seriously saying that in a forum dedicated to software engineering and technology?

I'm not sure what you're implying or maybe what you are thinking I implied. Maybe you think I have veered off topic for the forum, despite the topical article under discussion?

I think the suggestion is, humans aren't biologically disposed to fly either, but that's hasn't stopped them (that being the relationship to technology); so why should it dictate our role in society, where we collectively have even more freedom to structure things as we see fit?

That's just an odd statement since there are intrinsic differences in biology between the sexes. You can't ignore them. Heavy manual labor is typically a job for men because males have more body strength.

And until you can find a way for biological males to have a baby, biology is going to determine the role of childbearing.
