Research from DX CTO Laura Tacho, based on 121,000 developers across 450+ companies, reveals that while 93% of developers now use AI coding assistants, productivity gains have plateaued at roughly 10% and ~4 hours saved per week. AI-authored code now accounts for 26.9% of production code, up from 22% last quarter. Onboarding time has been cut in half when measured by time-to-10th-PR. However, outcomes diverge sharply by organization: well-structured teams see AI as a force multiplier, while struggling organizations find AI exposes existing flaws rather than fixing them. The key insight is that AI adoption alone doesn't drive results — real impact requires organizational-level change management, clear goals, fast CI, good documentation, and leadership support.

Something doesn’t feel right about this. 121k devs from corporates - ones that pushed for AI assimilation? Doesn’t that skew the statistics somehow?
I’m not an AI doomer, but I cast a huge doubt on these polls

Totally agree with this. Almost every developer I know is using AI now, but I don’t really feel a big productivity jump on existing/legacy applications.
Where AI really shines for me is new projects — when you already have a prebuilt structure, clear scope, and fewer constraints, the speed-up is obvious.
On mature codebases, AI helps, but it can’t magically fix architecture, process gaps, or tech debt. That still depends on the team and the org.

I am surprised who are those 7% developers that are not using AI!? At this point, everyone is using AI. Even the devs like Andrej Karpathy are using AI, or vibe coding to be exact.

Senior developer + AI = more code in minute
Junior developer + AI = same code as AI can without developer

we also use calculators, a mobile phone etc. whats the point of confirming the obvious. My mom is not a dev and she uses AI… And more, I don’t save time with AI, I add more time to do more things so in practice I work more
