Yes there are population biases in the hiring and funding data. No one denies that. What he said was "the top x% of the tech population". The tech distribution as a whole is already skewed. If talent was independent of race, you'd expect an equally skewed distribution at whatever talent threshold you set. That's how conditional independence works. His statement is implying that is not true, and that if you set the talent threshold high, you get a different racial distribution. That's a very important distinction, if that is indeed what he's saying. I really think this is what he's saying, because he's explicitly stating that large companies that recruit nationwide should be have a population equal to the skewed nationwide tech population, because they higher only "the top x% of the tech population". Not confounding geographic reasons (i.e. someone doesn't want to move away from their family), but specifically talent reasons.
