Gender roles still exist

[Basman]

They are just more advanced now.

Majority of people in elder care, teaching, kindergartens, etc. are women. Majority of people in infrastructure (housing, roads) and security (military, police) are men. Gender roles still exist today in practice but instead of a majority of a male/female population having those tradition roles, a minority specialize into those roles. Instead of all women caring for their kids all day, a minority of the women care for the kids of all the other women as their job. Same with the military and construction workers.

You could say it is just an expression of genders expressing a preference for certain industries, but I really think it is just a more advanced version of traditional gender roles, what we have today. It is less rigid, it is more effective as people can specialize and increase productivity, and it is more free as you are no longer strictly defined by your gender. 

It is just a more advanced version of the previous system. I don't believe traditional gender roles where truly abolished, instead it was upgraded and made better to what we have now (and more obtuse and indirect as well).
