Through, the culture is not just what people in tech do. These debates often comes up as accusing men in tech of being worst, but the "I am girl therefore I can't possibly like it, a girl who like tech (cars) have something wrong about her, it is not for me, wow I did not knew women can be programmers you must be smart" is internalized much sooner.

What also definitely does not help are odd ideas about what kind of personality can enjoy tech work. The best predictor imo is willingness to solve puzzles and personality that likes to learn. Meanwhile, people use "playing action games or clash of clans" as proxy. When i was studying, dudes who spend all their time on irc or muds were seen as potential genius programmers, cause they spend all time with computer. Most of them could do only a bit of administration, but they acted confidently.

Different interest thing is cop out. Tech is not magic, interest in it develops exactly like interest in anything else - starting from litterature and art, continuing though biology to astronomy or sport.

Whenever topic came out, it was "women just have different brain and are not naturaly as good". And people truly believed that. So I am kinda glad for "actually women have same aptitude" change, but if you are convinced the child is incapable in x, child will grow less interested in it - even if it is a music.
