: The takeaway seems to be "look, a small number of people at these companies have vile beliefs" which is so true of pretty much any company on Earth that it's essentially meaningless; the author wants to, but doesn't actually really manage to, make this about tech in particular.
There was one interesting bit that definitely made it about tech:
Such bias may be particularly rife in Silicon Valley because of another of its foundational beliefs: that success in tech depends almost entirely on innate genius. ...a 2015 study published in Science confirmed that computer science and certain other fields, including physics, math, and philosophy, fetishize "brilliance," cultivating the idea that potential is inborn. The report concluded that these fields tend to be problematic for women, owing to a stubborn assumption that genius is a male trait.
I haven't been immune to this particular bias. As I've gotten older, though, and raised a child, I've realized how much of my own ability to solve complex problems depends on plenty of sleep and lack of distractions. As a young white male who was "the smart kid" and expected to do smart things, I was given - much more than I realized then - the freedom to focus on learning and developing my problem-solving abilities. Everyone else had confidence that I was smart, so I got that confidence, too, and the privileges that came with it.
Now I'm learning how much work - cognitive load, emotional and physical labour - goes into raising a child and keeping house. Being smart under these conditions is much, much more difficult. My family was poor, but growing up I was still given the privilege of being allowed to think about challenging, interesting problems, and I was able to turn that privilege into a series of well-paying tech jobs. Did I have some innate problem-solving ability? Sure, maybe a bit. But I'm willing to bet that a lot of people have that innate ability, but never get to exercise it, never gain confidence in it, because it's assumed that they'll be doing non-technical work. They're the wrong gender, or the wrong colour, or they give off the wrong cultural signals.
Whenever this topic comes up, I think of the best example of true genius that I know: Euler, it is said, "calculated with one hand while bouncing a baby on his knee with the other." If anybody in tech thinks they're a genius, I give them that challenge. If you've only produced brilliant results and done smart things while being insulated from distractions and responsibilities, then there are probably a whole bunch of women and people of colour who would've done better than you had they been given, from childhood till now, your privilege.
