Alasdair Allan's QCon London talk hit 91 points on Hacker News, and the data is bleak for anyone early in their engineering career.
METR research shows AI task success drops from ~100% on sub-4-minute tasks to less than 10% beyond 4 hours. Anthropic's own internal trial found junior devs using AI scored 17% lower on mastery quizzes and performed significantly worse on debugging. Entry-level UK tech roles fell 46% in 2024, with projections hitting 53% decline by end of 2026. Teams with high AI adoption complete 21% more tasks but see 91% increases in code review time.
That last number is the one that keeps me up. The bottleneck shifts upstream to senior judgment. But senior judgment only comes from doing the work that AI now handles. We're cutting the rungs off the bottom of the career ladder while expecting people to show up at the top.
This connects directly to the Meta-Harness story. Harness quality requires the kind of systems thinking and debugging intuition that only comes from years of grinding through problems. If juniors never build that muscle because AI handles the grind, who writes the harness in five years?
Same day, Dario Amodei went viral saying "I have engineers who don't write any code" at Anthropic. "They just let the model write the code and they edit it." He predicted AI could take over most software engineering tasks within 6-12 months. Meanwhile, a 684-point HN post argued that writing IS thinking, and delegating it to AI kills the cognitive process where contradictions surface.
I don't know how this resolves. But I know that "AI makes everyone more productive" and "juniors who use AI learn 17% less" can both be true simultaneously. And that's a problem we're not taking seriously enough.
