#278 - AI Does NOT Replace Junior Developers, Here's Why

Description

Every headline says AI is eating developer jobs. But spend a week in production and you’ll see the opposite: brittle code, flaky tests, and tools that look fast until you actually ship something.


In this episode, I break down why the “AI replaces engineers” story sells so well—to investors, to execs, and to lazy headlines—but falls apart in the real world. We’ll talk through a Cornell + METR study showing seasoned devs got 19% slower using AI (even though they thought they were faster), and why that tracks with what I’ve seen on real teams.
