The Ladder Is Missing Rungs: QCon Talk Maps How AI Hollowed Out Engineering Career Progression — 91 Points
Alasdair Allan's QCon London talk (91pts, 45 comments on HN) presents hard data on AI's structural damage to the engineering pipeline. METR research shows AI success drops from ~100% on <4min tasks to <10% beyond 4 hours. Anthropic's own trial found junior devs using AI scored 17% lower on mastery quizzes and significantly worse on debugging. Entry-level UK tech roles fell 46% in 2024, projected 53% decline by end of 2026. Teams with high AI adoption complete 21% more tasks but see 91% increases in code review time — the bottleneck shifts upstream to senior judgment that can only be built by doing the work AI now handles.
