Female engineers posted their photos accompanied by the hashtag in order to counter the assumption that all engineers are men and look like Mark Zuckerberg. The truth is that most engineers are men, according to a recent study conducted by Stack Overflow that revealed that only 5.8 percent of developers worldwide are Successful Women.
In the United States, most agree that this number has something to do with American culture. The New York Times reported in 2012 that in a test given to 15-year-olds around the world, girls tended to outperform boys in science — the U.S. is an outlier.
Even in adulthood, women pursue science, math, and business less than men. Udemy, an online course platform, reports that only 15.4 percent of their enrollments in development courses are women, and only 11.3 percent of enrollments in IT and software courses are women.
But still, there are women in the technology sphere who are changing the world.
See below for some of the smartest, coolest, and most prolific women in tech.

Of the app, Wolfe told TIME, “This could change the way women and men treat each other, women and men date, and women feel about themselves.”
