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.
That finding comes from our Q3 2026 Dev Barometer, a survey of 705 developers and 41 CTOs. 67% report spending more time reviewing AI-generated code than they did 12 months ago, and time spent learning AI and new tooling has more than doubled.
Writing code got faster while judgment did not get any easier, and judgment is where the work sits now. 72% of developers say AI assists with at least a quarter of their code, against 33% a year ago. Code volume increased while the share of the week spent producing it decreased, which means more output moving through the same set of people qualified to approve it.
78% of the CTOs we surveyed increased investment in review and validation over the same period. The layer that used to be absorbed quietly is now being funded on purpose.
The job did not get lighter. It moved up a level, and that is a different kind of engineer than most job descriptions were written for.
