The author suggests that when these average statistics propagate into life decisions and employment preferences, you end up with an equilibrium with less females in these roles.

You write 'This can be used again to claim women don't belong in those roles' but the author did not use this to claim such a thing! 'I know several women' precisely coincides with what the author wrote. Again, he pointed out multiple times throughout that he was not generalizing but was merely looking at average trends.

In the aggregate, this is objectively true based on my observations, and you can see this exact same sentiment passionately expressed by feminists.

> ...there are some roles they might not be able to perform.

This part is your mind playing tricks on you. You have certain beliefs, and you are trying to find anything to confirm them.

You have misunderstood what the author was saying, I would suggest because you are not trying to understand it, but rather are trying to find examples to substantiate your worldview.

> Strip away his science and his words

....leaving us....your imagination?

That's absurd. You're not even interpreting his comments at face value. You're attributing a subtext to them that only exists in your imagination.

>Strip away his science and his words, he's a misogynistic techbro

What an absolutely hateful and sexist comment. It amounts to: "strip away his message and judge him by what identity group he belongs to"
