If all women everywhere are then I think he's right. What has kept the patriarchy in check has been differing civilizations and cultures. As a society becomes weaker through gynocentric ideologies, outside civilizations conquer the weaker ones. Currently, technology allows for total world enslavement to the matriarchy, that's why they push for globalism so much. I think, once globalism happens then total world collapse happens, perhaps even our species or some survive with far limited technology than what we have today and we start the cycle all over again. Men establish a patriarchy, women slowly chip away, the sons of men slowly forget why the patriarchy was established in the first place and everything that has already happened happens all over again. There is nothing new under the sun.
