I tend to lean toward the biology argument too but I do sense a cultural shift, albeit a slow one. The problem with trying to take a birds eye view of wants and desires is that we are forced to rely on surveys. And people are not 100% honest in surveys. They especially are not honest when dating apps survey them. Or maybe they are not honest with themselves. No one wants to shoulder the blame for failing at dating. It's far too easy to throw up your hands and complain about the opposite gender. So yeah, I agree with your top of your game observation.
