I don't see it going away anytime soon either. Honestly, I believe I could have worded this question much better. I think complementarianism is still very much a thing in Christianity and I don't have a problem with complementarianism in most regards. I've just noticed some changes in regards to gender in Christianity, some for the better and some not.
I think that as long as men and women are physiologically different, there will be those that use this to support the "practice" of complementarianism.
I think it is human nature to gravitate towards believing that if someone is different than you, they just might be better than you, and the defense against that is either covert or overt racism/sexism. The more adult a person is, the less likely they are to go there, though.
I will say this about that, though, and it has nothing to do with who is "better": When I was in sales in the 70's, I was VERY successful. I won a ton of sales contests. I actually gave classes to my co-workers on how to treat and speak to men vs women - at least at first until you get a feel for the attributes of the individual. Same with all other attributes, e.g. age, attire, etc.
When it comes to cultural stuff, the bible speaks in generalities. I think it's a mistake to take those generalities literally. Rather, they are instruction to someone that may be young and is still trying to grasp concepts that people over 40 understand as simply a part of how human culture works.
To use something I figured out at Boeing 21 years ago: There are three types of managers.
1. "By the book" managers. They get to first or maybe second level management and that's it. They are not decision makers. They do what "the rules" say, even when individual cases may need a "creative" response. I once read a story about a scientist being amazed watching ants excavate an ant hill. They would take a piece of dirt and walk it ten inches from the hole and drop it, and go back for more. He thought that was "intelligence". But then he saw them digging out an entrance in a vertical rotten tree and, though they could have just stuck their head out and dropped the dirt to the ground, they walked out ten inches from the hole and dropped it. They were not using intelligence. They were using pre-programming and nothing more. They were not decision makers.
2. Managers that break the rules at the wrong time. They get fired.
3. Managers that use the rule book as a guide, but take risks and sometimes break the rules because they "intelligently decide" that following the rules would not be the correct course of action in certain situations, and those decisions help the company "bigly". They become CEO's.
I aspire to be like number 3. I'm an imager of God (as we all are). He gave me a rule book (the bible) as a guide, but also a brain, which is exemplary at making decisions. When all you do is what the rules say, you're not really a decision maker.
But that is also "next level" thinking.
