Am I the only one who sees the elephant in the room? 15-30 is the prime time when women make relationships and men make money. Software engineering needs full time commitmentent and no personal life is a part of the deal. Someone who learns programming only in college will be mediocre at best and FANG doesn't want to hire mediocricy. so women have a choice: go into programming and forget about personal life, because the money they earn by 35 won't help them, or choose personal life and have no time for programming.
