"Suppose there was overwhelming evidence that 95% of women were terrible at technology and 5% of women were awesome at technology. There are roughly 7 billion people on the planet, roughly 3.5 billion women, roughly 1.5 billion women who work outside the house for a wage. In this scenario, where only 5% of women love technology, there are 75 million working women who are awesome at technology. According to the Bureau Of Labor Statics, the USA had 1,256,200 software developers in 2016. The BLS also tracks some other minor categories, such as Web Developer, which have about 150,000 jobs. Lump all the sub-categories together, and let’s say there are 2 million such jobs in the USA. Let’s be wildly generous and double the number for the EU, and triple it for Asia. That gives 12 million software developer jobs in all of the advanced and developing economies. So even with exaggerated assumptions about women’s inherent weakness in technology, we still end up with a scenario where every single programming job in the world can be filled by a woman who will be awesome at the job. There is no need for men, at all, in the tech industry."

More to point, women are being pushed out of tech. Women constituted 35% of all software engineers in 1990, but only 26% in 2015 (see above url). Given the rough figure of about 2 million jobs, that 9% difference suggests there are 180,000 missing women from engineering jobs right now. Initiatives like Duolingo help reverse the trend, and therefore should be praised.
