It's a cultural custom. Over here a few sciences are boys' clubs, being a nerd has been seen as unfashionable for decades. Being a computer nerd or hardcore gamer has been seen by western women as something for sweaty losers who would be womanizers if only they could leave the house. Most girls weren't getting into computers at 5 years old on their family PC and tinkering with random shit and modding their PC, playing with networking, being a skid, that kind of thing. These days this sex divide is far weaker in other sciences like chemistry and so on but CS bucks the trend.
In the east they never had these ideas to the extent that we do. In fact, computer science and IT stuff makes money, so they see it as a good thing to be doing, even women, and so they do it. I've talked to female techies from these places online, whereas their western counterparts are so uncommon it's not surprising to find out they're actually trans "girls".
There will still be a mismatch even over there since the bulk of women's rights are not even a single human lifetime old, and also because women are just more likely to give up a career to care for their children, but the divide is much weaker there.
