Adoption and confidence are different measures. This result describes respondents’ stated trust in accuracy, not an independent quality score.

The survey links that frustration to the debugging burden created when plausible output needs careful correction.

DORA lists work such as writing code, summarizing information and explaining code among those tasks.

The DORA finding reports respondents’ experience of improvement, rather than a controlled comparison between teams.

DORA found that many respondents expressed some trust, but the strength of that trust was often low.

This is a modeled association in DORA’s research. It does not mean AI alone caused the result for every team.

GitHub reported that the number of public generative-AI projects grew 98% year over year.

GitHub’s figure reflects contribution activity in public generative-AI projects, not all software development.

Developer surveys and platform activity show that AI is now part of ordinary software work. They do not establish whether a particular change is correct, whether a generated test checks the behavior that matters, or whether a passing result would detect a meaningful regression.
That is where a release review becomes specific. Teams can use AI to move faster, then ask which behavior changed, which failure would matter, what the test asserts, and what the available execution evidence actually establishes.
Speed can produce more code, more tests and more apparently reassuring green checks. The useful next question is not whether an AI tool was involved. It is whether the test makes a relevant claim about the changed behavior, and whether the team has evidence strong enough for the decision in front of them.
For a practical companion, read Code Coverage vs. Test Coverage, inspect the published evidence example, or try the free local behavior map.
Methodology and sources
This page compiles published figures from Stack Overflow, Google’s DORA research program and GitHub. Each statistic retains its original source, publication date and stated scope. Survey findings are reported as survey findings, and modeled associations are labeled as associations rather than universal causes.
