โIโm writing unit tests because I have to. They just confirm that my code works, which I already know. They are tedious to write, and often stop working when I change the implementation of the system. Maintaining unit tests is often difficult and takes a lot of time out of my day.โ

Jason GormanCircleCI's analysis of 28 million CI workflows confirms the same picture the DORA data shows. While feature branch activity's up significantly, the median impact on *main* (i.e. release) branch activity's net-negative 7%.
Only the top 5% of teams saw significant gains. The top 10% flatlined at 1%.
For the average team, AI slows them down overall.
Told ya!
What 28 million workflows reveal about AI codingโs biggest risk
In our last issue, we shared a preview of data from our upcoming 2026 State of Software Delivery showing that the promised AI productivity boom isnโt all hype. Throughput across the CircleCI platform increased 59% year-over-year, by far the largest productivity jump we've ever recorded and a clear i
