I imagine at least some of this would be caused by real or imagined productivity gains from AI tools for coding. The typical executive might have gone from thinking "staff up at all costs!!" to "AI will mean fewer devs doing higher value work". As these decisions have come from the top, the implication around wanting to "increase talent density" feels like there's less room for junior, lower skilled workers. And I can't help but think there's AI tools in the back of these execs minds.
