I specifically said that the situation in CS was better, because industry does such a good job competing for PhDs. When I was finishing my PhD in CS 15 years ago, doing a post-doc before applying for a tenure-track position was pretty rare, and only done if you felt that you'd benefit from it in some way. My friends are in the sciences, which has far fewer opportunities in industry. They're not going to end up in ad-tech either way.
