We were quite concerned about that when my son was starting college. Every single college brochure he got had girls on the cover and in most photographs.
Even the school he went to. He knew every single female student and none of them were the ones on the brochure.
His school was small with only a handful of female students.
I helped coach a FIRST Robotics team for a few years. Only one girl ever stuck with the mechanical and engineering side of things. The others were incredible at strategy, marketing etc but most never even put a fingerprint on the actual robot.
My daughter is in First Lego league.
She loves it, but I suspect that she will drift away eventually. While she gets a lot from her math teacher mother and I, her talents are not in engineering.
One of the many engineers I trained was a young woman was pushed into it by her mother. She HATED it with a passion. So much I was kind of shocked. So we sat down and developed a plan to get her to marketing and sales, where she is excelling because of her time in the plant.
