As a software developer, and someone with a degree in electrical engineering, I don't think the author understands what coding is.  
As far as the gender gap, go to any software seminar, and you will see the ratio of men to women.  From my experience it is way less than 25% women.  I find it interesting that there is a push towards STEM.  The fundamentals are still math and science, and have been around for many decades.  You still need to learn these if you are to understand and use 'coding'.
