Background & analysis
On November 1, 2026, DEV Community published an article citing a controlled study by Anthropic. The study asked 52 mostly junior engineers to learn Trio, a Python async library, and found that the group using an AI assistant scored 17 points lower on the follow-up quiz than the group that wrote the code by hand. The gap was widest on debugging questions, the article notes, which are the kinds of problems engineers get paged for at 3 a.m. The author describes it as the best-controlled study of its kind they have seen and concludes that, in this experiment, developers using AI performed worse. The article also links the finding to recent discussions about SREs losing incident-response skills as AI takes over alert triage and runbook execution, framing both as instances of the same skill-degradation problem.

A DEV Community post cites an Anthropic controlled study in which 52 mostly junior engineers learned the Python async library Trio: those using an AI assistant scored 17 points lower on a follow-up quiz than those who wrote the code by hand, with the widest gap on debugging questions. The author ties this to recent discussion of SREs losing incident skills as AI takes over alert grouping and runbook execution.

How is heat calculated?About the methodHide
Heat counts how many independent sources covered a story in the last 48 hours: one source counts once no matter how many posts it published, decaying with a 24-hour half-life. What ranks first is what many people are talking about.
