Twelve months ago, 12% of developers told us AI wrote half or more of their code.
We put the same question to 705 developers in our Q3 2026 Dev Barometer, and that number is now 42%.
@carlfranzen covered the findings for @VentureBeat. 🧵
AI is now saving developers 13 hours a week in coding, nearly double last year, but almost none of it has become free time.
The hours went into harder work: deciding whether what the tools produced is correct, and owning that decision.
Same question, same methodology, and twelve months in which AI assistance stopped being an experiment for most developers and became part of how the work gets done.
The number changed, but where those hours went turned out to be the bigger finding.
Cut headcount to capture AI savings, and the work those roles were doing doesn’t disappear. It reappears, informally, on your senior engineers and operators.
