The Jewish religion is extremely gynocentric, their bloodline is traced through the female.
Robot waifus with wombs essentially erase judaism as their lineages end or are relegated to old matriarchies that will be allowed to exist. They'll basically become reservations.
She's right to be very afraid as the few jews that still exist will have to do what they hate the most: labor. Last time they had to work, they invented a new word for it (holocaust) and promised to never again work.
