The problem with this framing is that it treats a mass exodus as if it were selective pruning. Losing 10,000+ STEM PhDs in weeks isn’t a quality filter. We’re hemorrhaging institutional capacity. We lose researchers who understand decade-long datasets, technical experts who can evaluate contractor claims, and people who can actually critique scientific literature when making policy decisions.

Where’s the evidence these specific 10k were the low performers? The more likely scenario is that better performers left because they have options, while weaker performers stayed. If the issue is quality, you’d want systematic performance review, not mass departure driven by factors unrelated to competence.
