New METR research reveals that AI‑assisted coding tools actually slow experienced developers by 19% and increase debugging effort by roughly 50%. The study also highlights a rise in security flaws and a gradual erosion of core programming skills as engineers become dependent on AI output. The video dissects these findings, explains why AI‑generated code often skips refactoring, and warns of a "janitor" role where developers clean up machine‑produced messes. It concludes with a Tactical‑Architectural‑Human framework—a three‑step system designed to keep AI on a leash while preserving developer expertise.

The video opens with a personal crash that jolted the speaker out of a complacent CTO mindset and frames seven subtle habits that can silently wreck a developer’s career. It positions these habits as industry‑wide symptoms rather than individual failings,...
