By "more women needed in technology", what it appears to actually be advocating is "more women needed in designing products for women, because men are condescending in their design of female-oriented products".
... and ok. Then the author follows it up by saying "it's basic economics! More women will buy your products!", but doesn't follow that up with "and so market forces will make it happen!". But whatever. If you want to try and change how an industry talks to your group, have at it.
But then also the author has taken the time to produce a cartoon book telling young women to go in to computers and technology, because (from the image provided) apparently all young women ever hear is badly-spelled messages telling them that they should focus on home economics (untrue) and that programming generally involves working in dark cubicles (sometimes true) and being a nerd (all too true). Why doesn't the author already know that ...?
Because the author, and head of this campaign ... isn't actually a woman in technology. She's a woman in advertising, who has decided that more women need to be in technology. Not her, just other women. So how does she know that women can thrive in technology? How is she able to legitimately address their concerns? It all feels a bit condescending towards ... people in technology. "Here I am, a person outside of your field, telling you that you talk to women all wrong, and I'm going to fix it with a swish advertising and graphics campaign".
If you want the message to be taken seriously, get Marissa Meyer to say it. Bring me the opinion of Danese Cooper. Shouldn't tech role models come from, ya know, tech?
Conclusion: the message I probably agree with. Diversity of every sort in technical teams is a great thing in my previous experience. But what the hell is this article about, and who is this advertising exec to tell deliver it?
