Note that the qualification "outdated" has been added by you, not the parent.
One could have easily said "evergreen" or "tried and true" or "resilient" roles.
Also not being reliant on what's enabled by the available technology for major choices is more than about "being prepared in case society collapses".
For one, technology is neutral, it can enable all kinds of things, including things that are bad for society. What should be going should be a cultural/ethical/etc discussion, not a knee-jerk adoption of any new available option.
Not saying that this is the case here, but there's more to being logical than your critique of the parent.
If you want to make the case that the gender roles are not outdated, be my guest.
The parent brought up the idea of society collapsing. Not me. If you have something to add please do, otherwise you are just kicking up dust.
There has been a cultural/ethical discussion going on and a great many people decided that gender roles needed to change. If you 'aren't saying that's what happened here' how is your comment relevant?
All you have attempted to do here is add doubt without adding substance or logic of your own. If you can actually argue your position, go ahead, but engaging in this kind undermining suggests that not only can you not, you are aware of it.
Your other comments on this topic show that your suggestion that you are merely trying to point out that my logic isn't as strong as it could be is a misrepresentation of your view.
At least it's clear what kind of logic you are using.
