## Scope

49,009 responses from 177 countries, fielded 29 May to 23 June 2025, and self-selected: respondents were recruited through Stack Overflow's own channels, so this measures the people who answer Stack Overflow, not a random sample of developers. It is recorded against reviewing machine-written code rather than against writing code, because what it measures is the volume driver and the verification response, not who writes what. Both halves belong here: 84% use or plan to use AI tools (76% a year earlier) and 51% of professional developers use them daily, while favourable sentiment fell from over 70% in 2023 and 2024 to 60%, more developers actively distrust the accuracy of AI tools (46%) than trust it (33%), and the most experienced report the lowest rate of high trust at 2.6% against the highest rate of high distrust at 20%. The stake cuts both ways and that is unusual enough to state: Stack Overflow's own traffic is what AI coding assistants displace, so the adoption finding runs against its commercial interest while the falling-trust finding runs with it. The survey does not say what the tools were used for, whether any review took longer, or what any of it changed about shipped code.

## What this means

A worker-adoption record on reviewing machine-written code: the work exists because generation got cheap, and this measures both sides of that at once — 84% of 49,009 developers use or plan to use AI tools and half the professionals use them daily, while the people with the most experience report the highest distrust of the output. Volume up, confidence down, on the same page of the same survey.

## What it does not show yet

Worker adoption is not employer deployment: this counts what individuals reach for, not what an organisation put into its process. It is a self-selected sample recruited through Stack Overflow's own channels, and it does not say what the tools were used for, whether review took longer, or what changed about the code that shipped. Distrust is a stated attitude, not a measured error rate.

## How to verify it yourself

Take the last five changes your team merged and mark which ones contain code no person wrote line by line. Then compare how long each sat in review against the same five a year ago. The survey measures the thing driving the volume; your own repository is the only place that says whether the review load actually moved.
