Testosterone in men has been dropping for decades, testosterone in women is rising. We are literally witnessing a reversal of the roles between men and women. From patriarchy we are slowly entering matriachy, and we are already in a gynocracy. Basically men still "rule" but at the ground level, women have far more social power. Being an aggressive muscled up alpha isn't being selected for anymore because it doesn't help in todays society. It just gets you arrested. The modern survival mechanism is instead being highly social, extroverted and aware of how to navigate modern society.
Also in terms of looks women don't like overly masculine looking men anymore, they want prettyboy tiktok mofos with feminine features (this is also due to the change in hormones in women because it has been proven that as women have more estrogen they prefer masculine gigachads more but lower estrogen females prefer prettyboys, so as women get less estrogen and more test, they will prefer prettyboys more).
