Obviously, you can say that the amount of interest by the two sexes is not the same, but apparently there was more interest by girls back in the 1980s. Why is it different now? That seems to be the question that no one is asking.
To be clear % is a bullshit statistic. In the 1980s CS was teeny tiny. In the 90s all of my friends wanted to go into CS because they wanted to make video games. So in the 80s there was probably a broad academic interest which attracted both men and women just like chemistry or biology or engineering. And then in the 90s you suddenly had a huge influx of video game geeks wanting to learn how to make a video game. That large influx of programmers who probably would have been screwed got the luckiest break in 100 years and an entire industry exploded around them giving them employment opportunities outside of programming game engines.
I can't think of anyone who went into CS who I went to highschool with who was talking about how excited they were to go into CS and learn how to program mobile apps.
In my degree program (Visual Effects and Animation) it was almost exclusively male. The women in the program joined because they loved pixar movies and wanted to do animation. The men mostly loved star wars and wanted to blow shit up. Almost all of them will end up green-screening corporate talking heads. A lot of these niche industries like CS are similarly bait and switch teasing a career in something awesome and then delivering a homdrum run of the mill job.
We need to find the CS equivalent of "Video Game Developer" to attract women. Because "Hey you can work on the database that drives Facebook!" isn't really attractive to highschool boys let alone higschool girls looking to pick a major and doubling down on recruiting using purely practical factors doesn't work.
So to answer the original headline's question. I would say no, probably not. CS has successfully attracted a lot of men by using Boy-Focused games (guns and explosions). So I would suspect the best approach to women is exactly the same... deception and trickery to make CS seem relevant to the things they already like.
