A bunch of SJWs are wrestling with it. Silicon Valley is doing just fine.
When women wanted to become doctors, they fought their way into med school, fought to earn a proper education, fought for credentials, and fought for equal standing amongst male doctors. When women wanted to become lawyers, they similarly fought their way through the system. Same goes for every other job women wanted to do. Women fought their way to get the jobs they wanted. Some of those fights took decades.
In tech, jobs require less qualifications than working as a doctor or lawyer. You don't need to spend years getting a masters, PhD, or going through a post-doc program. The pay for high-end IT workers can reach the same amount as the pay for low-end doctors or lawyers. The work environment in IT is often better than what doctors or lawyers encounter. Yet, tech companies can't give away the jobs to US women.
Why? Answer that question and you get to the root of the problem.
Women like to help. They'll help people, animals, forests, the environment, etc. But in general, they're not interested in working with machines. Machines don't need help. They don't care about making the next hipster app. They could care less about the coolest new programming language. They don't give a shit about all the things that cause religious wars in the tech community.
Most women don't want tech jobs because they find the work meaningless. Having done a great deal of the work myself, I'd also throw in soul-crushing. I've spent years developing apps for companies that ultimately went bankrupt. The product of my years of work? Gone. Thrown away. Has my work actually helped anyone? Hard to say. Probably not. Definitely not directly. Not in any meaningful sense. Say, I spend 3 months improving the performance of an app. Then users login half a second shorter. Big whoop. Do users even notice? Do they care? No, probably not. Does it really improve their lives? Definitely not.
When tech companies start doing truly meaningful work, then women will beat down their doors. Until then, all this effort to attract women won't matter.
