These initiatives will simply not work. Imagine "Men Nurse."
Many women SIMPLY do not code for the same reason many men do not code. Most of us were not exposed to the science as kids, hence step 1 is to make Programming mandatory. Note I say programming and not C.S.. I am an amateur programmer and I can say wit confidence that this is as fundamental as basic arithmetic. Full stop.
I frankly wish they shut down "Girls Who Code" entirely and all the likes. Instead we can put our efforts into teaching everyone to code: "We Code." Because once someone does something as simple as print (2+2)-(3-2) or print $first_name + $last_name or (my favorite) <html><h1>The Website of Me</h1><p>My name is Joanna. This is my first web page.<img src='..'></p></html>, once they do this, there is simply no going back for them.
